Experiments comparing conventional and organic systems often report similar yields despite substantially higher weed abundance in the organic systems. A potential explanation for this observation is that weed-crop competition ...
Introduction of cover crops in a maize–soybean rotation of the Humid Pampas: Effect on nitrogen and water dynamics
The continuous cropping system of maize-soybean rotation in the Humid Pampas poses a risk for the leaching of nitrogen. The purpose of this study is to determine the effect of fall-winter cover crops and a mixture of oats ...
