Índice de floculação e agregação de um Latossolo Vermelho sob dois sistemas de colheita da cana-de-açúcar
(2009-07-01)
The objective of this work was to evaluate the soil physics and chemical attributes of Rhodic Ferralsol, in sugarcane systems harvest compared with soil forest. The treatments were consisted by native forest, manual and ...
Chemical and Spectroscopic Characteristics of Anthrosol (Amazonian Dark Earth) and Surrounding Soil from the Brazilian Amazon Forest: Evaluation of Mineral and Organic Matter Content by Depth
(Soc Brasileira Quimica, 2020-08-01)
The chemical and spectroscopic characteristics of soil organic matter (SOM) isolated from Amazonian dark earth (ADE) and surrounding soil (SR) were evaluated according to the soil depth. The results showed opposite trends ...

(Sociedad Chilena de la Ciencia del Suelo, 2008)
Chemical modifications in solarized soil with addition of organic residuesModificações químicas em solo solarizado, com e sem incorporação de resíduos orgânicos
(2008-01-01)
The soil solarization is used in small properties as an alternative for control of phytopathogens and weeds, besides it also can affect the availability of some nutrients and phytotoxic elements in the soil. Thus, one ...
Recuperação da estrutura de um Latossolo vermelho degradado utilizando lodo de esgoto
(2015-01-01)
The aim of this study was to investigate the influence of sewage in the recovery of the structure of a degraded Red Latosol (Oxisol) being cultivated for 4 years with eucalyptus (Eucalyptus citriodora) and (Brachiaria ...
Potential for increasing soil nutrient availability via soil organic matter Improvement using pseudo panel data
(Scientific Research Publishing, 2014-07)
Fixed and random effect models were applied to a pseudo-panel data built of soil analysis reports from tobacco farms to analyze relationships between soil characteristics like soil organic matter (SOM) and soil nitrogen ...
Soil organic matter-metal interactions in Chilean volcanic soils under different agronomic management
(MARCEL DEKKER INC, 2002)
The organic matter existing in volcanic soils must be investigated not only in quantity, but also in quality in order to understand its role in soils and thus ensure adequate levels of stable organic polymers contributing ...
