The soil properties reported in areas with different management provide useful information about the systems’ operation, state of conservation and resilience. In this way, this study evaluated physical properties and organic matter dynamics of soil under different plant covers in seven areas consisting of: five areas under ecological restoration (REC1 to REC5), an areas with native vegetation (MATA) and a sugarcane crop area (SC), all located in State of Mato Grosso do Sul, a transition area between the Cerrado and Atlantic Forest biomes. Samples were taken at the 0-10 and 10-20 cm layers and were analyzed for soil density (Ds), macroporosity (Ma), microporosity (Mi), total porosity (PT), weighted mean diameter (DMP), aggregate stability index (IEA), and the particle sizes of organic matter. There were no differences in DMP between the areas, however, sugarcane crop area and areas under ecological restoration (REC 1, 3 and 4) had high values of density and microporosity and low contents of the fractions of organic matter, which can promote a greater restriction to the root development of plants. Among the areas under restoration, REC1 and REC5 presented physical conditions with higher similarity to the native vegetation area. Changes in the physical soil properties and parameters such as Total organic carbon (COT), confirmed that the restoration practices applied improved the soil quality.

Soil quality can be defined as the ability of a soil to function within the limits of ecosystems (natural or cultivated) to perform one or more functions related to plant sustainability and productivity, maintain or improve environmental quality and health promotion of animals and man (Karlen et al., 1997). The sustainability of an environment can be estimated by the evaluation and monitoring of soil properties that are sensitive to changes through use and management over time, from which the evolution of soil quality is evaluated (Nascimento et al., 2014). Understanding the interactions between plant biodiversity, soil properties and their impact changes can be useful in restoration actions in degraded areas (Mueller et al., 2014) in the long term, and serves as an important tool to monitor the state of conservation of natural ecosystems, because they allow to characterize the current situation, to alert to situations of risk and, sometimes, to predict future situations, especially when adopting native vegetation as reference (Cardoso et al., 2011).

Studies have demonstrated the importance of indicators as a mechanism for understanding the quality or state of conservation of several systems (Aragão et al., 2012; Moline and Coutinho, 2015; Cherubin et al., 2016). Among the physical properties, aggregate stability has been used worldwide as an indicator of soil quality (Duchicela et al., 2013; Spaccini and Piccolo, 2013; Stott et al., 2013; Karlen, 2014; Zornoza et al., 2015) due to its crucial role in stabilizing and protecting carbon in physical processes related to water and air dynamics, and providing resistance against soil erosion (Cherubin et al., 2016), as well as being an essential property to plant development, because it describes the desirable physical conditions in which the soil is friable and contains a set of pores that allows the movement of water and air that contributes to the germination and emergence process of seedlings (Niewczas and Witkowska-Walczak, 2005).

The content and dynamics of soil organic matter (MOS) are also properties representing soil quality and that can be altered with soil use and management (Guimarães et al., 2013). A soil with good quality should not only present high levels of MOS, it also needs a balance between the stages of organic matter decomposition (Caetano et al., 2013). The components that can be considered as good indicators of soil quality include the labile (with lower degree of decomposition) (Loss et al., 2009) and stable (high degree of decomposition) fractions. By means of the particle size fractionation of MOS it is possible to quantify the COp and the organic carbon associated with mineral (COam) (Cambardella and Elliott, 1992), which are efficient fractions to identify changes resulting from soil management practices or the replacement of natural areas by agricultural crops (Torres et al., 2014) over the years.

From the practical point of view and considering the environmental interest, studies on changes in soil structure (Portugal et al., 2010) and soil organic matter dynamics induced by the soil management is of major importance to understand the effects of use and land occupation, adoption of support restorative practices and help in understanding ecological processes advocated by the ecology of restoration.


Study area characterization

The study was carried out in the municipality of Rio Brilhante, State of Mato Grosso do Sul (21°48’ S/ 44°32’ W). The soil is classified as Hapludox Eutrophic, and is of clayey texture (Embrapa et al., 2013). According to the Köppen classification system (Cwa), the climate is characterized as humid mesothermal, hot summers and dry winters. The study areas consisted of a remnant of native vegetation, with floristic physiognomy of a transition area between Cerrado and Atlantic Forest, which was adopted as a reference area and identified as MATA, and five areas under ecological restoration (identified as REC1 to REC5) and an area of sugarcane crop (SC).

The sugarcane (RB86 - 7515) planting was performed with conventional tillage using harrow plow, one sub soiling to a 0,45m of depth and a leveling harrowing. During the planting crop was used NPK fertilizer (05-15-10), and to the annual cuts the replacement was done using NPK fertilizer (30-05-25) in the rows of the crop. To the cultivation of sugarcane ratoon crop operations was carried out between the rows, to minimize the effects of soil compaction caused by intensive traffic of machines in the harvest. At sampling (rainy season 2014), the sugarcane crop was at the fourth mechanized harvest.

The areas under restoration were originally established in a seasonal semi-deciduous forest and replaced by pasture (Brachiaria brizantha), managed in a ten year-period, and later by the sugarcane crop for two years. After this period, areas were allowed for environmental recovery. Due to the location, fragments destined for recovery were identified as REC1 to REC5, with the adoption of natural recovery and planting of native forest species, such as Myracrodruon urundeuva, Schinus terebinthifolia, Handroanthus avellanedae, Machaerium stipitatum and Dabergia miscolobium, among others, in the area identified as REC2 and natural recovery in other areas. In all areas there was no mechanical intervention and fertilizer application.

Experimental design

Soil density (Ds), total porosity (PT), macroporosity (Ma) and microporosity (Mi) were calculated using undisturbed samples collected with Uhland sampler in steel cylinders (Kopecky) with sharp edges and internal volume of 100 cm³ at the layers 0-10 and 10-20 cm, with four random replicates in each layer in the evaluated areas.

To evaluate the aggregation and stability of aggregates and carbon fractions, four small trenches were dug with the aid of a straight blade to allow the removal of soil monoliths in the 0-10 and 10-20 cm layers in each area studied. Samples were stored in plastic bags of 10x10x10 cm that allowed the storage and transportation without major damage to the samples.

Laboratory procedures

For the determination of soil density and total porosity (macroporosity and microposity) according to the methodology described by Embrapa (1997). For evaluation of aggregates and determination of their stability, we adopted the procedure of Kemper and Rosenau (1986), modified by Salton et al. (2012).

For the determination of total carbon content, an aliquot of each class of soil aggregates obtained was completely ground and sieved through 0.150mm mesh sieves, with a subsequent weighing of 0.150g of this aliquot for dry combustion analysis (TOC- L, Shimadzu®).

The evaluation of the MOS fractions (COp and COam) was performed using the particle size fractionation method described by Cambardella and Elliot (1992). The carbon stock in organic matter associated with mineral (COam) was calculated by the difference between the COT and COp (> 0.053 mm) (Torres et al., 2014).

Statistical analysis

The obtained data were subjected to the Shapiro-Wilk test to check normality and the Levene’s test to check homoscedasticity. Data that presented normality and homoscedasticity were tested by analysis of variance (ANOVA), and the means were compared by the Tukey’s test, at 5% significance.

Data of the analyzed variables were also subjected to Pearson correlation and multivariate analysis, among which, principal component analysis (PCA), using the Vegan package in the software platform R (R Development Core Team, 2015) and cluster analysis, using the furthest neighbor method (complete linkage) and Euclidean distance to describe the similarity between evaluated areas.


Changes in soil physical properties and Distribution of soil aggregate classes

At the 0-10 cm layer, the lowest values of soil density (Ds) were observed in the area with native vegetation and the largest values, in the sugarcane crop area. The areas under ecological restoration presented intermediate values, however, it is noticed that REC1 and REC5 presented values closer to the area MATA (Table 1). Our findings corroborate Silva et al. (2013), who found lower values of Ds in native vegetation area. According to the authors, this fact may be related to higher carbon contents, as observed in herein (Figure 1A), and by Blum et al. (2014) evaluating the physical properties of a Typic Hapludox subjected to a no-till system. It may be also related to the great biological diversity (Gama-Rodrigues et al., 2008), favored by the deposition of diversified plant residues.

FIGURE 1 Total organic carbon (COT), particulate organic carbon (COP) and organic carbon associated with mineral (COam) in the 0-10 (a) and 10-20 cm (b) layers (n = 4) of a Hapludox Eutrophic in Rio Brilhante, State of Mato Grosso do Sul. REC1 (area under ecological restoration 1), REC2 (area under ecological restoration 2), REC3 (area under ecological restoration 3), REC4 (area under ecological restoration 4), REC5 (area under ecological restoration 5), SC (Sugarcane), MATA (fragment of native Seasonal Semi-deciduous Forest). Different letters for the same fraction of soil organic matter are significantly different by Tukey’s test at 5% probability. 

Nevertheless, based on the critical values of Tormena et al. (2008), who consider critical values of Ds above 1.16 for clayey soils, and Reichert et al. (2009), values above 1.35 as critical for the establishment of the root system of plants in very clayey soils (62% clay), only the area under native forest did not present values of Ds potentially restrictive to development of plants in the surface layer.

In turn, at the 10-20 cm layer, the results indicated that the restoration areas REC2 and REC3 presented high values of Ds, not statistically differing from SC. The other areas under restoration (REC1, REC4 and REC5) presented intermediate Ds values, not differing from the native vegetation and sugarcane crop areas, which presented statistically lower values. Adopting the criterion established by Reichert et al. (2009), REC1, REC5 and MATA did not present Ds values that could impair the root growth of plants, since they are associated with soil clay content. On the other hand, the substitution of native vegetation for production systems probably induced soil compaction due to the increase in Ds values and Ma decrease, as pointed out by Cherubin et al. (2016).

Based on the results of macroporosity of both layers, it can be observed that REC1 and REC5 were not significantly different from MATA, reflecting in a better state of physical recovery of the soil. The other areas under restoration (REC2, REC3 and REC4) showed similar values to the sugarcane crop area (SC), indicating unfavorable structural conditions to the full development of plants, when adopting as critical the values below 0.10 m³.m-3 (Taylor and Ashcroft, 1972).

The volume of micropores in the superficial layer was high in all evaluated areas, except for REC1, which presented statistically lower values. In the subsurface layer, the lowest volume was observed in MATA, followed by SC. However, greater microporosity does not necessarily imply restrictions on plant development, since the soil conservation status should also take into account the values of macroporosity, soil density, penetration resistance, among others. Thus, analyzing the set of physical variables measured in this work, the areas MATA, REC1, REC5 presented a better state of physical conservation of the soil.

Values of total porosity ranged from 0.44 to 0.52 m3. m-3, reflecting good physical soil quality in the surface layer, according to Kiehl (1979), who considers that the ideal distribution of total porosity is close to 0.50 m3.m-3. At the 10-20 cm layer, REC2, REC4 and SC presented statistically lower values in comparison to the other areas evaluated. In these areas, in both layers, it can be inferred a greater restriction to the root development of plants, since the values of total porosity in these areas are result of the low macroporosity and high volume of micropores and density value that imply a greater degree of soil compaction. In MATA, the good distribution of total pores may be associated with root system diversity (Calgaro et al., 2015) and the edaphic community, input of organic matter of varied composition and absence of machinery traffic (Mazurana et al., 2017;), which has significative effect on soil compaction (Feng et al., 2019) in agricultural systems.

In the areas under ecological restoration, besides the forest species, grasses are important in the addition of organic material and soil restructuring (Assad, 1997; Talema et al., 2019), since they have a root system capable of forming continuous channels of pores, water storage in the soil and soil decompaction (Marchini et al., 2015), a fact that may have contributed to the process of restoration of soil physical properties in some restoration areas.

When analyzing soil aggregation in different areas, the results indicated no significant difference in the values of DMPs and DMPu in both studied layers end little variation in the sites (data not show). Clayey soils with predominance of grasses, without turning over and with constant input of carbon, in general, present good aggregation. This can be related to the root system of plants and to the degree of soil consolidation due to its lower mobilization (Veiga et al., 2014). Moreover, researchers have reported that high carbon contents (Loss et al., 2014), clay and root production result in higher DMP values (Vezzani and Mielniczuk, 2011).

Salton et al. (2014) stressed that larger and more stable aggregates are the result of increased biological activity, including the growth of roots and fungal hyphae and the presence of residues of plants, insects and other organisms. Under these conditions, more complex and variable structures are formed, including macroaggregates. In this context, Fattet et al. (2011) and An et al. (2013) verified the importance of roots in soil stability and demonstrated that herbaceous species are very efficient for the stability of soil aggregates.

Changes in soil organic matter fractions under different plant covers

The total organic carbon (COT) presented a different behavior among the plant covers, with values significantly higher in MATA (41.49 and REC5 (32.83 and lower in SC and other restoration areas which showed no significant differences from each other in the 0-10 cm layer (Figure 1). At the 10-20 cm layer, there was no difference in COT concentrations between the studied areas.

The highest COT values registered in MATA and REC5 may be related to the greater diversity of plants and density of tree species, which result in greater input of plant residues to the soil (Alcântara Neto et al., 2011), the texture and temperature, as reported by Cherubin et al. (2016). This demonstrated that the replacement of native vegetation by sugarcane crop resulted in a reduction in the COT content by 41.21% in the surface layer, however, the conversion of the sugarcane area into areas under ecological restoration promoted increases of 21.32%, 13.53%, 17.01%, 9.14% and 34.60% in REC1, REC2, REC3, REC4 and REC5, respectively, suggesting the existence of a dynamic process of soil improvement.

Reductions in COT levels were reported in the literature as a result of the conversion process and the low carbon input in the system due to the low productivity of dry biomass and inadequate management (Cherubin et al., 2016).

The results obtained in this work corroborate with Batista et al. (2014), which verified that productive systems have lower COT contents when compared to native vegetation (Savana), suggesting incomplete cycles of decomposition and humification of organic matter, thus causing carbon losses during these processes when isolated from sustainable agriculture practices (Naresh et al., 2018).

The concentration of carbon in the particulate organic matter (COp) ranged from 5.38% to 11.65% of soil COT in the 0-10 cm layer, with higher contents in REC5 and MATA (Figure 1A). At the 10-20 cm layer, the COp contents ranged from 3.29% to 9.59% of soil COT, with higher values observed in MATA, followed by REC2 and REC5 and the lowest values in CN, REC1 and REC4 (Figure 1B). The negative effect of soil tillage on the particulate fraction of MOS was verified with the reductions of 48.03% and 38.22% in SC when compared to MATA in the layers of 0-10 and 10-20 cm, respectively; thus it represents an efficient and sensitive indicator for detecting changes caused by management. Due to its sensitivity, the particulate fraction can be used as an indicator of soil quality in which changes in soil COT have not yet been of great magnitude (Conceição et al., 2005, Naresh et al., 2018) and indicate changes in labile carbon resulting from changes in soil use (Loss et al., 2014).

Regarding the organic carbon associated with minerals (COam), in the superficial layer, the highest content was found in MATA and the lowest, in CN, REC2 and REC4 (Figure 1A). At the 10-20 cm layer, it was observed that the use and management of the soil did not affect its proportion (Figure 1B). As COam presents a much slower cycling, as for its formation and decomposition, it is necessary a longer period for the alteration of the management systems to have effect on the carbon content of this fraction (Bayer et al., 2004), as verified by Trivedi et al. (2015), who underpin that the abundance of genes involved in the recalcitrant carbon degradation did not change due to the adopted management practice, indicating that carbon storage in the soil can remain unchanged in the long run. Spaccini and Piccolo (2013) highlight that small disturbances on soil from the reduction of tillage methods inhibit the aerobic microbial decomposition of the soil organic matter and, therefore, limit the degradation of soil aggregates and consequently the losses of organic carbon of the system.

Multivariate analysis on physical properties and organic matter fractions of the soil

The explained and cumulative variances of the first two main components extracted in the principal component analysis (PCA), in both layers, accumulated and explained the greater data variability (77.96% and 80.83%, respectively). In this way, as the contribution of the other components was minimal, these were not considered in the analysis.

The areas under ecological restoration, sugarcane crop and native vegetation influenced soil physical properties, as indicated by the different groups formed in PCA (Figure 2). The sum of the variability retained in the components explained 77.96% of the original data variability concerning the effects of the different areas on the physical variables of the soil, in which PC1 and PC2 retained, respectively, 49.98% and 27.98% of the information of the surface layer (Figure 2A). At the 10-20 cm layer, the sum of the variability retained in the components explained 80.83% of the original variability of the data, in which PC1 and PC2 retained, 47.47% and 33.36% of the original information of the data, respectively (Figure 2B).

REC1 (area under ecological restoration 1), REC2 (area under ecological restoration 2), REC3 (area under ecological restoration 3), REC4 (area under ecological restoration 4), REC5 (area under ecological restoration 5), SC (Sugarcane), MATA (fragment of native Seasonal Semi-deciduous Forest). 

Analyzing Figure 2A and its respective axes, in the upper left quadrant of the vertical line are the ecological restoration areas, REC2 and REC4, while in the lower left quadrant are REC3 and SC. The areas REC5 and MATA are in the upper and lower right quadrant, respectively. In Figure 2B, restoration areas REC2 and REC5 are in the upper left quadrant of the vertical line, MATA in the lower left quadrant and REC3, REC4 and SC are in the upper and lower right quadrant, respectively.

At the surface layer, areas under ecological restoration (REC2, REC3 and REC4) were more strongly associated with Ds and MI contents than with the other physical properties of the soil, and it can be inferred that they are areas that present a greater restriction to the root development of plants due to the possible higher degree of soil compaction. REC5 and MATA presented better physical conditions of the soil in the superficial layer, since they were associated with PT and IEA and the organic matter fractions (COT, COP, COam) and MA, respectively, corroborating with Batista et al. (2014), who observed association of the oxidizable carbon fractions with Savana area.

The best physical conditions of the soil at the 10-20 cm layer were observed in the group formed by MATA and REC1, and in the group formed by REC2 and REC5 that were associated with high values of MA and IEA, PT, COT, COP and COam, respectively.

With the hierarchical clustering analysis for the set of physical properties studied and the organic matter fractions without distinction of layer, it was possible to divide two interpretive groups (Figure 3). In this analysis, the areas under ecological restoration, sugarcane and native vegetation were grouped according to their degree of similarity, classifying them into homogeneous groups, confirming the distribution of areas in the PCA.

FIGURE 3 Euclidean distance dendrogram based on soil physical properties in areas of ecological restoration, native vegetation, and sugarcane crop. REC1 (area under ecological restoration 1), REC2 (area under ecological restoration 2), REC3 (area under ecological restoration 3), REC4 (area under ecological restoration 4), REC5 (area under ecological restoration 5), SC (Sugarcane), MATA (fragment of native Seasonal Semi-deciduous Forest). 

In the interpretation of the similarity matrix between the areas, a cut was made in the Euclidean distance at seventy eight, allowing a clear division of groups ordered by means of the set of physical properties and the fractions of organic matter, constituting the group GI, that encompasses the data representing the areas REC1, REC5 and MATA, and the GII group formed by REC2, REC3, REC4 and SC. Nevertheless, when cutting the Euclidean distance at forty-two, demonstrating the areas with the highest similarity, four groups were formed: I and IV represented by REC1 and CN, respectively, were isolated from the other areas, group II formed by MATA and REC5 and group III represented by REC2, REC3 and REC4. The formation of groups with a greater degree of similarity corroborate the concept that the soil management can influence the behavior of the physical properties of the soil, consequently affecting the system resilience.

The clustering analysis of the areas based on the degree of similarity, without taking into account the soil layers, allowed to infer that the areas under restoration present different dynamics regarding the restitution of integrity parameters, since only two of the five areas under restoration studied showed greater similarity with native vegetation area and the others presented greater physical restraint of the soil and greater similarity with the area of sugarcane crop.

These results allow to infer that the reduction of the cultural management and gradual increase of the plant diversity by restoration practices and successional process are followed by greater deposition of plant residues with varied composition and protection of the organic matter of the soil associated to the improvement of the soil properties and quality. These factors are important and related to the increase of resilience in these places.

The modern production, especially in tropical countries, need to be supported by sustainable practices that are important to the environment preservation and protective to human and soil health. Conservation agriculture practices increase soil quality, providing sustainable food production with minimal impact on the soil and the atmosphere (Naresh et al. 2018).

The adoption of management strategies in the area of sugarcane crop, such as the maintenance of straw, application of organic residues as complementary fertilization, adoption of minimum tillage and no-till together with the control of the agricultural machinery traffic can collaborate for the soil fertility, soil carbon sequestration and mitigate deleterious impacts on soil physical properties (Cherubin et al., 2016).


The analyses applied to data of physical properties and fractions of soil organic matter indicated that the traditional soil management resulted in changes in the soil quality, leading to increased density and microporosity, which may reflect higher compaction and attenuation of physical protection of organic matter, as well as surface runoff of water, low infiltration rates.

Among the areas under restoration, REC1 and REC5, in general, presented physical properties and organic matter fractions of the soil with greater similarity to the native vegetation area, which indicates that in these areas the intervention was most efficient.

The restitution of soil integrity parameters in areas that underwent replanting of vegetation cover by planting native seedlings or suspending management with agricultural activities has its own dynamics, even in relatively close areas, with similar soil type and classification, suggesting interactions associated with biological activity, deposition and behavior of organic matter in soils.

The cultivation of sugarcane resulted in changes in soil quality.

The restitution of soil integrity parameters in areas that have undergone replanting of vegetation cover by planting native seedlings or suspending management with agricultural activities present their own dynamics, even in areas with relative proximity, type and classification of soil , suggesting interactions associated with biological activity, deposition and behavior of organic matter in soils.

In spite of the increasing demand on the issues about the importance of recovery of forest resources and the need to preserve them, especially those with specific functions and occupying areas of permanent preservation, the studies that guide and evaluate the restoration of these areas are still insufficient due to the complexity of the ecological processes involved.
