Title A name given to the resource Qualidade da matéria orgânica e distribuição do fósforo no solo de lavouras orgânicas de café Conilon Organic matter quality and phosphorus distribution in soils under organic Conilon coffee Creator An entity primarily responsible for making the resource Henrique Duarte Vieira, Luciano Pasqualoto Canellas, Fábio Luiz Partelli, Jader Galba Busato, Alexandre Pio Viana Description An account of the resource O cultivo de café orgânico utiliza fontes não solúveis de fósforo e grande quantidade e variedade de material orgânico em seu manejo. Assim, o objetivo do trabalho foi avaliar as frações que compõem a matéria orgânica e distribuição do fósforo no solo de cafeeiros Coffea canephora da cultivar 'Conilon' cultivados sob diferentes sistemas de manejos de produção orgânica. O solo foi coletado na projeção da copa do cafeeiro, na camada de 0 a 20cm. Determinaram-se as características químicas e granulométricas do solo em procedimentos de rotina e as frações de fósforo e da material orgânica. Na maioria das lavouras, o fósforo orgânico constituiu a maior parte do fósforo lábil, e a fração humina constituiu a maior parte da matéria orgânica. Houve maior presença de fósforo inorgânico nos solos das lavouras com maiores concentrações de fósforo total e lábil. O conteúdo total de Pi + Po nos solos avaliados apresentou valores elevados, variando de 426,9 até 910,4mg dm-3 de solo. A fração humina constituiu a maior parte da matéria orgânica. As frações que compõem a distribuição do fósforo no solo apresentaram discrepâncias entre os sistemas de manejos de produção orgânica.The organic management in coffee uses insoluble phosphorus sources and a large quantity and variety of organic material. Thus, the objective of this research was to evaluate organic matter composition and phosphorus distribution on soils from Coffea canephora cv. 'Conilon' crops, under different organic management production systems. Soil under the coffee tree canopy was collected from 0 to 20cm depth. Chemical and soil texture characteristics were determined by routine analysis as well as phosphorus and organic matter constitution. On the average crops organic phosphorus was the main part of the labile phosphorus and carbon humine. There was a higher content of inorganic phosphorus on soils from the crops with the highest concentrations of total and labile phosphorus. The total content of Pi + Po in the evaluated soils showed high and variation from 426.9 to 910.4mg dm-3 of soil. The humin fraction formed the bulk of organic matter. The fractions that make up the phosphorus distribution in the soil showed discrepanncies between the organic management production systems.
