“…The determination of protease activity in acid and forest soils, the soils which suffered from degradation processes is an ef¿ cient method of soil-ecological monitoring. The degraded soils present a wide ¿ eld for studies in the sphere of ecological soil studies, as they are the ¿ rst to be subject to recultivation, which are ecologically safe due to their susceptibility [25].…”

Aim. The aim of this work is to optimize and facilitate current methods of ecological diagnostics of soils of different genesis under the infl uence of various external loads. Methods. Laboratory-modelling (physical- chemical, biological): determination of acid-base buffer ability of soil (DSTU 4456:2005); determination of the activity of calcium ions (DSTU 4725:2008); determination of the activity of protease was performed by modifi ed Mishustin’s method. Results. The methods, proposed by us, speed up the ecological diagnostics of soils considerably regardless of their origin and external factors. This facilitates monitoring of soil resources and reveals the factors that infl uence the course of soil processes negatively or positively. These methods have already become the basis of “Methodology of operational diagnostics of the infl uence of natural and anthropo- genic loads on the functional stability of acid soils”. The proposed methods can be used not only by the scien- tists of specialized scientifi c institutions, but also by farmers (in case of available minimal instrumental equip- ment). Conclusions. A modifi ed photoautography method has been developed on the basis of the laboratory of hydromorphic and acid soils fertility of the NSC ISSAR named after O.N. Sokolovsky, NAAS of Ukraine, for the determination of enzymatic activity by the parameters of the protease enzyme. The abovementioned tech- nology is based on Mishustin’s method of determining protease activity. In addition, this method may be used to determine the rate of protease action in different soils under various tillage conditions and under different loads. The diagnostics of acid-base state of soils by ion-selective methods with the determination of the levels of activity of calcium ion and soil pH, modeling of the loads on soils (natural and anthropogenic), determina- tion of acid-base buffer capacity change of soil under the infl uence of loads and determination of biological activity due to the activity of protease allow to determine the functional stability of each soil in rather a short period of time in order to further increase/maintain it. As the fi nal stage of the diagnostics, we proposed a for- mula of calculating the coeffi cient of functional stability of soils (K f.st.), based on their genetic features. It is also very important that this scientifi c development does not require high fi nancial costs, and gives the fullest possible picture of the soil state in the current period.

The study of soil physical properties is a theoretical and practical basis for choosing of a cultivation system. It is an important agri-acceptance of modern agriculture. In the scientific literature, many publications in periodicals is devoted to the study of soil physical properties. In this paper are shown features of study of physical parameters of soils on southern chernozem, which characterized by low-humus content under different cultivation systems for corn: plowing, chisel, No-till and grassland are highlighted. The methodological features of the research are described in detail in the paper. Determination of physical parameters for different soil tillage systems showed that the five-year application of No-till for maize significantly improved compared with the plowing, the structural composition of the southern chernozem was 62.4-66.6 %, and the aggregates had a rounded form with pronounced porosity. Soil density was also optimal within the range of 1.10-1.26 g / cm3, which gives grounds for positively assessing the investigated agriculture measure and the possibility of its introduction into production.
