Abstract

Summary

An important aspect of ensuring the sustainability of agriculture is the implementation of environmentally safe practices, in particular, the use of intercropping of agricultural crops and the use of non-traditional organic fertilizers in crop fertilization systems. The aim of the work was to study the impact of the use of biological products and mixed crops on the structural composition of the soil and soil density. Our research was carried out in an experiment in the Right-Bank Forest-Steppe of Ukraine on chernozem typical. In the experiment, mono-sowing of peas, barley and combined sowing of peas, barley and beans were compared, as well as 6 fertilizer options. It was established that the optimal soil density is formed when using compost and vermicompost separately and together with mineral fertilizers. Sowing a three-component mixture contributed to a decrease in the density of the composition of typical black soil compared to mono-sowing of barley and peas. The best structural state of the soil was noted when using compost where the structural coefficient was 6.68–6.70. Application of vermicompost improved the water resistance of soil aggregates. Thus, intercropping and the use of organic fertilizers significantly improve the agrophysical condition of typical chernozem.
