Spatial variability of soil erodibility in pastures and forest areas in the mun...
Silva,Lucivânia Izidoro da; Campos,Milton César Costa; Brito,Wildson Benedito Mendes; Cunha,José Maurício da; Lima,Alan Ferreira Leite deAbstract “Erodibility” is a characteristic of the soil that represents the susceptibility with which its particles from the most superficial layer are taken and transported to lower places by erosive agents, causing environmental and economic damages. This work estimated soil erodibility in pastures and forest areas in the municipality of Porto Velho-Rondônia. In the field, three areas with different types of v...
Soil attributes and root distribution in areas under forest conversion to culti...
Lima,Alan Ferreira Leite de; Campos,Milton César Costa; Martins,Thalita Silva; Brito Filho,Elilson Gomes de; Cunha,José Maurício daABSTRACT The objective of this work was to evaluate soil attributes and root distribution in areas under forest conversion to cultivated environments. The study was carried out in four areas: forest, cupuaçu, guarana and annatto, located in the municipality of Canutama, state of Amazonas. Soils and volumetric rings were collected in the layers 0.00 – 0.10; 0.10 – 0.20; 0.20 – 0.30; 0.30 – 0.40; and 0.40 – 0.50 ...

Pantoja,José Carlos Marques; Campos,Milton César Costa; Lima,Alan Ferreira Leite de; Cunha,José Maurício da; Simões,Emily LiraAbstract The recognition of the influence of management practices on soil physical and chemical conditions is substantial for sustainable agriculture. For this reason, this study was developed for the purpose of evaluating the behavior of soil attributes under different uses in the region of Humaitá, AM, using multivariate statistical methods. The study was developed in 8 rural properties producing bananas, gra...
