Summary in the original language of the document
Este estudo teve objetivo de avaliar indicadores físicos e biológicos do solo que, inseridos no Módulo complementar “Capacidade produtiva do solo”, avaliem o impacto das práticas agrícolas sobre diferentes manejos do solo. Para efeito comparativo e complementar, serão avaliados os indicadores químicos. Análises de parâmetros químicos, físicos e biológicos foram realizadas em cinco propriedades de cada sistema, orgânico e convencional, selecionadas em Ibiúna e Socorro, SP. Em todas as propriedades, os indicadores físicos estabilidade de agregados, aeração e compactação contribuíram para os impactos ambientais (IA) negativos, conseqüência do baixo aporte de matéria orgânica diversificado, solos descobertos e com excessiva mecanização do solo. Este fato foi complementado pela presença de mofo branco (Sclerotinia sclerotiorum) e redução da atividade microbiana no solo.
Summary translation
The goal of this work was to evaluate physics and biological indicators, at the complementary module “soil’s productive capacity” and, also soil chemical indicators added to APOIA-NovoRural system supports. To comparative and complementary effect, chemical indicators was evaluated. Chemical, physical and biological parameters evaluation was made in organic and conventional production system in two regions in Sao Paulo state. In both regions and in both systems (convencional and organic) the physics indicators (aggregates stability, aeration and compaction) was negative, result of low input of diversified organic matter, expose soils and excessive mechanization. Moreover it was observed the presence of white mold (Sclerotinia sclerotiorum) and reduction of the microbiological activity in the soil.
