Soil pore distribution as affected by cattle trampling under no-till and reduced-till systems
Soil pore size affects soil air and water dynamics, and thus influence crop productivity. The aim of this study was to evaluate the impact of reduced-tillage (RT) and no-tillage (NT) systems on soil pore distribution under animal grazing. The soil was sampled at 0-5, 5-10, 10-15 and 15-20 cm depths...

The soil was sampled at 0-5, 5-10, 10-15 and 15-20 cm depths before and after animal grazing.
