SILVEIRA JUNIOR, Otacilio et al. Establishment of pastures under monoculture farming and integrated with biofertilizer using poultry litter as a nutrient source. Rev. bras. saúde prod. anim. [online]. 2015, vol.16, n.3, pp.499-512. ISSN 1519-9940.

The objective was to evaluate the effect of the use of bio-fertilizers obtained by anaerobic biodigestion Aviary bed productive characteristics of Piatã, grass and soil chemical characteristics. Assessed five doses of biofertilizers (0; 10; 20; 30; 40m3. Ha-1) in two cultivation systems (monoculture system of Piatã grass and grass intercropping system with hybrid forage sorghum Piatã BRS 610). Agronomic characteristics were verified and submitted to structural measures of biofertilizer in the two systems of crops, checked also the influence of biofertilizer in soil chemical characteristics. The two production systems responded efficiently with the application of biofertilizer, however the thatched roofs and tilling was the main components responsible for increased productivity. The doses of biofertilizer brought chemical soil characteristics increments, being identified only difference to K+ and organic matter between systems of crops, evidencing the Member with the highest extraction system of soil nutrients by crops. The biofertilizer proved satisfactory considering increments obtained in the production of fodder, in tiller number, leaf area, mass per tiller being good option for improving the productivity of grass Piatã, responding positively in both production systems.
