The maintenance and accumulation of soil organic matter are considered the best option of addressing this problem and to ensure a sustainable production.
The purpose of this study was to evaluate different fractions of organic matter, and carbon and nitrogen contained in these compartments of a very clayey dystroferric Red Latossol under different crop rotations and at different depths under long-term no-tillage in Dourados, state of Mato Grosso do Sul.
The experiment was arranged in a randomized block design with three replications, and the treatments in a 5x4 factorial design, with five crop rotation systems (1 – vetch ...
