Dynamic of organic matter in the conversion of primary forest in rubber tree in the central amazon region. The removal of primry forest causes a significant reduction of the microbial biomass of C and soil fertility. With the introduction of stands of rubber tress can be a continuos recovery of the amount... ... Repository: BDPA Publication year: 2007
The role of soil organic matter in sustainable crop production in the Tropics. Soil organic matter has long been recognized as important indicator of soil productivity. Repository: BDPA Publication year: 2011
Management impacts on soil organic matter of tropical soils. Increased soil organic matter (SOM) improves the cation exchange capacity of tropical weathered soils, and liming is required to achieve high yields in these soils. Despite a decrease in SOM in the sh... ... Repository: BDPA Publication year: 2015
