ABOUT SOIL FERTILITY AND ITS MONITORING IN BIOFARMING SYSTEM
The article analyses soil fertility problem, determining the productivity of modern agriculture and the possibilities of its growth together with ecological qualities while going to biological agriculture, minimizing the consumption of chemicals and increasing the role of natural biological processes: preservation of ploughing and others horizons of soil; alternation of plant crops with different root system types; use of postharvest crops and green manure crops for balance control of organic substance, carrying out agroforest melioration activities, and also using microbiological specimen, accelerating the processes of organic humification and mineralization. The article defines the soil fertility monitoring system, some particular elements of which require the attention of subject matter experts. Particularly it concerns means and methods of organic balance control of soil, whose complicated dynamics defines the processes of its preservation, humification and mineralization.
