Rye cover crop biomass and nutrient uptake applied for soybean rotation.

Kansas farmers are planting cereal rye as a cover crop after corn in order to follow soybean crops. The rye is being used so even more dead residues is laying the soil to support the beans to be more meshed and cleaned during the growing season, besides as the rye residues have a light color if properly managed, it reflects the sunlight conserving more moisture to the soil also avoiding weeds to spread it out and generating the right biomass. The non-uniform and sparse RCC stand would however reduce effectiveness as a cover crop. Termination on the cereal rye crop can be regulated according on how dry the spring actually is so farmers can save more moisture. Such application eventually saves water inputs also.
