Influence of potassium humate on the productivity of annual grasses and biological soil activity
During the conduct of a microfield experience with the podzolized heavy loamy chernozem we revealed the high efficiency of a foliar application of annual grasses with potassium humate for herbage. It is shown that three-time spraying with potassium humate vegetative mass of annual grasses increases the yield of herbage, the content of crude protein and potassium, it increases the harvesting of dry matter and yield of feed and grain units and contributes to the activation of soil biological activity (decomposition of fiber, cur- rent nitrification).
