The soil is one of the main C pools in terrestrial ecosystem, capable of storing significant C amounts. Therefore, understanding the factors that contribute to the loss of CO2 from agricultural soils is critical to determine strategies reducing emissions of this gas and help mitigate the greenhouse effect. The purpose of this study was to investigate the effect of soil tillage and sugarcane trash on CO2 emissions, temperature and soil moisture during sugarcane (re)planting, over a study period of 15 […]

The physical and chemical properties of coastal plain soils cultivated with sugarcane for a long period under different management systems may undergo changes. The objective of this study was to evaluate the effects of different sugarcane management systems on the chemical and physical properties of a dystrophic cohesive Yellow Latosol of coastal tablelands in the state of Alagoas. Three experimental plots were selected in sugarcane growing areas, representing the three management systems used for ethanol production, namely: a cultivated area […]

The potential yield of sugarcane depends on factors related to climate, soil and the plant variety. Management systems that provide the addition of organic waste to the soil can cause changes in physical attributes of the soil, enhancing the growth of the root system and sugarcane yield. The objective of this study was to evaluate the effects of different management systems at several levels of organic residue addition on the distribution and indices of aggregate stability of dystrophic cohesive Yellow […]
