 Autoria: CASTRO, G. S. A.; CRUSCIOL, C. A. C.; CALONEGO, J. C.; ROSOLEM, C. A. 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... ... |
 Autoria: VIANA, J. H. M.; ALVARENGA, R. C.; ALBUQUERQUE FILHO, M. R. de; COSTA, A. M. da; MOURA, M. S. de Soil organic matter (SOM) is sensitive to changes in land use and is a key indicator of soil quality. This work evaluates the evolution of the organic matter of an oxisol under a crop-livestock integr... ... |
