Abstract

In a present article the results of land fund investigation of Vasylivka Rural Counsil in Onufriivka region of Kirovohrada oblast in Ukraine and agricultural lands productivity monitoring of land use entity Limited Liability Company "Maryivske" are given. It was established that lands are low-yielding (2.5 Mg ha-1 of crops and leguminous plants) and ploughed up to 71%. The implementation of measures of agricultural chemicals rational use showed that their productivity reached 100%. It is reasonable to calculate the rates of local fertilizer distribution, taking into account soil chemical characteristics, provided by plants protection products adding and bioactive substances.

... A negative correlation of pH with springtails, was recorded by (Fazekašová & Bobuľovská, 2012), who identified it as the main soil parameter influencing Collembola communities. Soil arthropods are involved in ecosystems in maintaining the natural balance and material cycle of the biogenic elements such as carbon, nitrogen, sulfur and phosphorus (Brygadyrenko, 2016) and they have more suitable conditions in sustainable agriculture (Saranenko, 2011). ...

Soil arthropods respond sensitively to land management practices and correlate with beneficial soil functions. The aim of this research was to determine soil quality using the QBS index in different types of crops and influence of soil variables (pH soil, soil moisture, potassium, phosphorus and nitrogen) on soil arthropods. Between the years 2018 and 2020, we studied different types of crops (Brassica napus, Pisum sativum, Triticum aestivum, T. spelta, Zea mays, Grass mixture and Hordeum vulgare) and recorded 14 taxa. Our results suggest a higher QBS index value in crops grass mixture, Pisum sativum, Triticum aestivum, T. spelta. The EMI value grew with increasing values of soil moisture, soil pH, phosphorus, potassium and nitrogen; indicating the presence of soil arthropods occurring in higher quality soil. Our results suggest that agricultural intensification affects soil arthropods, which are important for the production of biomass, which also affects crop yields.
