Abstract

DALCHIAVON, Flávio Carlos; CARVALHO, Morel de Passos e; MONTANARI, Rafael  and  ANDREOTTI, Marcelo. Sugarcane productivity correlated with physical-chemical attributes to create soil management zone. Rev. Ceres [online]. 2013, vol.60, n.5, pp.706-714. ISSN 0034-737X.  http://dx.doi.org/10.1590/S0034-737X2013000500015.

The socioeconomic importance of sugar cane in Brazil is unquestionable because it is the raw material for the production of ethanol and sugar. The accurate spatial intervention in the management of the crop, resulting zones of soil management, increases productivity as well as its agricultural yields. The spatial and Person's correlations between sugarcane attributes and physico-chemical attributes of a Typic Tropustalf were studied in the growing season of 2009, in Suzanápolis, State of São Paulo, Brazil (20°28'10'' S lat.; 50°49'20'' W long.), in order to obtain the one that best correlates with agricultural productivity. Thus, the geostatistical grid with 120 sampling points was installed to soil and data collection in a plot of 14.6 ha with second crop sugarcane. Due to their substantial and excellent linear and spatial correlations with the productivity of the sugarcane, the population of plants and the organic matter content of the soil, by evidencing substantial correlations, linear and spatial, with the productivity of sugarcane, were indicators of management zones strongly attached to such productivity.

Keywords : precision agriculture; geostatistical; management and conservation of soil; Saccharum spp.; spatial variability.
