Implantação de pastagens sob sistema monocultivo e integrado com lavoura utilizando biofertilizante de cama de aviário como adubação de cobertura

Abstract: ResumoObjetivou-se avaliar o efeito da utilização de biofertilizante obtido através da biodigestão anaeróbica da cama de aviário nas características produtivas do capim Piatã, e nas características químicas do solo. Avaliou-se cinco doses de biofertilizantes (0; 10; 20; 30; 40m3.ha-1) em dois sistemas de cultivos (sistema monocultivo de capim Piatã e sistema consorciado de capim Piatã com sorgo forrageiro hibrido BRS 610). Foram verificadas as características agronômicas e estruturais submetidas às doses de bi… Show more

“…Satisfactory results resulting from organic fertilization were found also in other species, such as basil, which in addition to chicken manure, received mineral complementation (Blank et al, 2005). Silveira Junior et al (2015) reported an increase in Piata grass biomass using different doses of biofertilizers derived from the poultry manure digestion. Beyond merely supplying nutrients, the positive effects in the soil such as increased microbial activity, improved aeration and water infiltration in the soil profile, it provided better plant growth, resulting in the largest mass production with organic fertilizer, in the two species tested, in relation to controls and mineral fertilizer.…”

“…Sendo assim, é necessário a intensificação racional dos sistemas cultivados (LEAL et al, 2017), buscando-se maiores produtividades com menores gastos com insumos (SILVEIRA JUNIOR et al, 2015;ERASMO et al, 2017).…”

“…Pasturebased animal production systems have sought production models based on improved soil quality, in which pasture areas can benefit by the rational use of animal manures for fertilization, ensuring the production, economy and conditions for environmental protection (Alonso & Costa, 2017). For that matter, the continuous use of pig slurry (PS) in areas with annual crops provides a higher concentration of P, K, Cu and Zn in the topsoil compared to mineral fertilization (Scherer et al, 2010), while the poultry litter presents N, Ca, P, K and Mg in adequate concentrations to meet the plants development demand (Silveira Junior et al, 2015). The high production of animal waste due to the expansion of the poultry industry and the pig activity allow the availability of these wastes and their uses in organic fertilizer form.…”
