Biosci. j. (Online); 39 (), 2023
The usage of spatial tools might be helpful in the optimization of decision-making regarding soil management, with technologies that assist in the interpretation of information related to soil fertility. Therefore, the present study evaluated the spatial variability of chemical attributes of the soil und...

Organic matter compartments in an Ultisol under integrated agricultural and livestock production systems in the Cerrado

Ciênc. rural (Online); 52 (10), 2022
Integrated agricultural production systems have the potential to increase organic matter content, which is reflected in the soil carbon (C) and nitrogen (N) concentrations. Here, we evaluated the C and N stocks and its compartments in a typical distro cohesive yellow Ultisol under the no-till (NT) and cr...
