INFLUENCE OF BULK DENSITY OF CHERNOZEM SOIL ON MINERAL NUTRITION BY DIFFERENT SORTS OF SPRING BARLEY
Abstract
In the article there are shows the influence of the density of arable layer of chernozem soil on the removal and use of the main nutrients by different sorts of spring barley and their productivity; calculated the economic efficiency on application fertilizers at various levels of soil density. It is proved that a high level of soil compaction (1,4 g/cm3) leads to a decrease in the assimilation of nutrients by barley plants, which leads to a decrease in crop productivity.
