ABSTRACT New strategies for sugarcane production have been very important since the incorporation of ethanol in the Brazilian energy mix in the early 1970s. Prior to planting sugarcane, the soil is prepared, and this process can affect root development and, consequently, sugarcane production. This study was conducted in an area of sugarcane crop renewal in the Cerrado biome (Brazilian tropical savanna), with the objective of identifying which tillage system generates the better root development and improved yield in sugarcane. The […]

ABSTRACT The sugarcane green harvest system, characterized by mechanized harvesting and the absence of crop burning, affects soil quality by increasing crop residue on the soil surface after harvest; thus, it contributes to improving the physical, chemical, and microbiological properties and influences the soil carbon content and CO2 flux (FCO2). This study aimed to evaluate the spatial and temporal variability of soil FCO2 in sugarcane green harvest systems. The experiment was conducted in two areas of sugarcane in São Paulo, […]

PHYSICAL PROPERTIES OF AN OXISOL WITH COVER CROPS IN NO-TILLAGE

The use of no-tillage systems associated with the use of cover crops and crop rotation changes some soil physical properties and may indicate change in soil quality. This study aimed to use the aggregate stability index (IEA) and the sensitivity index (SI) to assess changes in soil physical attributes with the use of different plant cover after twelve years of no-tillage. We used a randomized block design with the following types of cover crops: sunn hemp, millet, sorghum, brachiaria, and […]
