The no-tillage (NT) management is widely used in the Cerrado region, but some questions remain unanswered, for example about the need of liming and adequate nitrogen rates for commercial crops when preceded by cover crops. Our objective was to evaluate the effect of precedent cover crops on the maize demand for nitrogen fertilization and forms of liming preceding the adoption of no-tillage management (NT) in different growing seasons. The experiment was arranged in a randomized block factorial design 5 x […]

Soil management systems and fertilization types make differentiated amounts of mineral elements in the soil profile available. The objective of this study was to verify alterations in chemical attributes of a Red Latosol (Typic Haplustox) of Brazilian Savannah under organic and mineral fertilization, vegetation cover in no tillage and conventional tillage systems, and with bean and cotton crops. The experiment had a randomized complete block design with split-plots. Two treatments of soil preparation (no tillage and conventional tillage) were installed […]
