ABSTRACT The land use changes and different management forms promote modifications in soil organic matter (SOM), which imply the yield sustainability of agricultural systems. SOM provides essential elements for plants, such as Nitrogen (N), one its main constituents, is also an indicator quality. This study aimed to evaluate dynamics N levels stocks Plinthosol state Tocantins, Brazil, under uses (eucalyptus, corn, pasture) compared a natural ecosystem Cerrado sensu stricto. Therefore, six...
An adequate amount of soil organic matter is considered essential for long-term sustainable agriculture, ensuring good productivity. Therefore, the present study quantified carbon and nitrogen stocks microbiological activity in three different areas: Forest-pasture System, Pasture System preserved Caatinga - used as a reference experiment located semi-arid region, Watershed Pajeú River, state Pernambuco, Brazil. Eight trenches were opened each system to collect samples at depths 0 10, 20 30...
