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
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... ... Repository: BDPA Publication year: 2021
Humic substance fractions and attributes of histosols and related high-organic-matter soils form Brazil. Knowledge of the distribution of soil organic matter (SOM) fractions is important in managing soils toward a sustainable agricultural system ina tropical environment, However, data on Histosols in lim... ... Repository: BDPA Publication year: 2007
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... ... Repository: BDPA Publication year: 2016
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... ...

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
Soil organic matter quality in Jatropha spp. plantations in different edaphoclimatic conditions. The substitution of native vegetation by agricultural ecosystems can change the quantity and quality of soil organic matter (SOM), and the intensity of these changes depends on the soil type, climate,... ... Repository: BDPA Publication year: 2017
Evaluation of the stability of soil organic matter in different types of livestock management. Repository: BDPA Publication year: 2016
Changes in the soil structure and organic matter dynamics under different plant covers. Repository: BDPA Publication year: 2019
Impact of deforestation on the soil physical and chemical attributes, and humic fraction of organic matter in dry environments in Brazil. Deforestation of Caatinga and inadequate land use of these dry environments have impacted soil quality in Northeastern Brazil. The objectives of this study were: (a) to evaluate the effect of deforest... ... Repository: BDPA Publication year: 2022
