The role of soil organic matter in sustainable crop production in the Tropics. Author(s): FAGERIA, N. K.; FERREIRA, E. P. B.; KNUPP, A. M. 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. Author(s): CASTRO, G. S. 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... ... Repository: BDPA Publication year: 2015
Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. Author(s): MADARI, B. E. Soil organic matter (SOM) is usually quantified by Walkley-Black titration method or using a spectrophotometric method. This study proposes an alternative method for quantification of SOM using digita... ... Repository: BDPA Publication year: 2021
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Author(s): SAGRILO, E. Soil amendment with pyrogenic organic matter (PyOM) can sequester carbon, increase mutualistic root symbioses with arbuscular mycorrhizal fungi and nitrogen-fixing rhizobia, and hence improve crop yie... ...
