Abstract
Aim. To perform biological evaluation of 60-year-long application of different variants of fertilization in terms of the number of microorganisms, transforming the compounds of nitrogen and carbon. Methods. Microbiological methods – determining the number of microorganisms, transforming the organic compounds and nitrogen, statistical processing. Results. It was determined that the application of a crop rotation with legumes and the variant with complete mineral fertilization on meadow-chernozem carbonate soils formed a balanced composition of microbial cenosis and the most optimal conditions for humus accumulation and nitrogen transformation. Conclusions. The microbiological monitoring demonstrated that it is possible to achieve non-degradation development of meadow-chernozem soil at the quasi-stable level in case of applying the 10-fi eld crop rotation with legumes (clover) and complete mineral fertilization.
Highlights
The soil cover of Ukraine has been studied rather well, but the intense process of soil degradation has not been stopped
In our studies the number of ammonifying and amylolytic microorganisms (Table 1) in the meadowchernozem carbonate soil depended on the variant of fertilization and decreased with depth
A similar regularity was obtained for the number of amylolytic microorganisms, here their decrease in the 10–20 cm layer compared to 0–10 cm layer was 10–67 %
Summary
The soil cover of Ukraine has been studied rather well, but the intense process of soil degradation has not been stopped. The main reason of the mentioned problems is underestimation of the actual danger of soil degradation for future generations, lack of understanding of the fact that the fertility of soils is the actual value of arable lands, which requires technological measures, aimed at its preservation [1, 2]. According to the data of the UN Food and Agriculture Organization (FAO), the agricultural activity has resulted in considerable degradation processes. Soil degradation is a relevant problem for Ukraine, directly impacting the fertility of soil and the quality of agricultural products, which brings about economic loss (over USD 6 billion a year) [3]. The solution of problems, related to the management of land resourc-
