Development and Implementation of Effective Schemes for the Use of Mineral Fertilizers in the Forest-Steppe Zone of the North Kazakhstan Region

Abstract

Nitrogen fertilizers in liquid form have become the most common ones in recent years. Since North Kazakhstan is located in a zone of risky farming, liquid fertilizers are a very productive solution. The purpose of the study was to develop and evaluate the implementation of effective schemes for the use of mineral fertilizers in the forest-steppe zone of the North Kazakhstan region. In the experimental areas of the fields, studies were carried out on cereals and oilseeds, with spring wheat as the preceding crop. Sowing was carried out five days after the introduction of the urea ammonium nitrate solution UAN-32. The use of the UAN-32 preparation in experiments with cereals and oilseeds gave a positive effect. Thus, in compliance with all agrotechnical measures and optimal sowing dates, the introduction of fertilizers in pure form into the soil before sowing and into fertilizing did not cause heat damage in plants. The increase in yield compared to the non-fertilized background averaged 39.4% for wheat, 42.9% for rapeseed, and 63.2% for flax. According to the results of the conducted studies, it can be noted that oilseeds, due to their greater consumption of nutrients for the formation of the crop, in particular nitrogen, are more responsive to the introduction of readily available forms of mineral fertilizers.
