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. Repositório: BDPA Ano de publicação: 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... ... Repositório: BDPA Ano de publicação: 2015
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. 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... ...

Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. 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... ... Repositório: BDPA Ano de publicação: 2021
Evolution of the soil organic matter content after 15 years of crop livestock system. 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... ... Repositório: BDPA Ano de publicação: 2021
Organic matter content and composition in a sandy loam Amazonian Acrisol as affected by soil management. The agricultural production in the State of Acre (Brazilian Amazon Southwest) is still very incipient and, so far, none investigation about the effect of soil management systems on organic matter (OM)... ...

Cover crops affect on soil organic matter fractions under no till system. The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to Fe... ... Repositório: BDPA Ano de publicação: 2016
Organic matter of an Amazonian sandy soil as affected by forest burning. In the Amazon region, forest burning is still common in spite of the governmental control. Pyrogenic C produced by the fire, due to its aromatic structure, may represent a C pool of small turnover rat... ... Repositório: BDPA Ano de publicação: 2017
The quality of soil organic matter, accessed by 13C Solid State NMR, is more important than its content concerning pesticide adsorption. The need for food will increase by 59-98% from 2005 to 2050, and its global growth production has been achieved mainly through the intensive use of inputs such as pesticides and chemical fertilizers.... ...
