摘要

In Northern and Central Kazakhstan, soil is notable for its deficit of phosphorus and nitrogen. Studies have shown that 50% of the cultivated area in this region are exposed to phosphorus shortage [1]. An agrochemical analysis showed that deep and root habitable layers are exposed to nitrogen element shortage. Therefore, the introduction of phosphorus and nitrogen fertilizers for spring crops in said regions is especially effective. Studies confirmed that this measure alone is capable of providing additional two-three hundredweight per hectare of crop yield [2].
