Александр Михайлович Семенов What is discussed and justified is the necessity of a wide use of the “soil ecosystem" (SE) category as more objectively meaningful and concrete term rather than the concise but differently conceptual term - “soil". The modern soil ecosystem is subdivided into natural and antropogenic or agroecosystem, and the latter is subdivided into conventional, organic and low input agriculture based on exploitation technologies; the key characteristics of organic, conventional and low input agriculture are also analyzed. A new general characteristic of the soil ecosystem is discussed - soil health (SH) and its scientific parameters. The methods of determining soil health in the form of parameters are given. The heterotrophic parameter of soil health (HPSH) and key provisions for perfoming this method and the subsequent ones are described. A new parameter for determining soil health is presented and discussed in the form of a parameter for assessing the self-sufficiency (PSSE) of the soil ecosystem by key biophilic elements, nitrogen and phosphorus. The approaches to the development of parameters for assessing suppressive activity and the control of “pathogenesis” in the soil ecosystem are discussed. The necessity of assessing the health of the soil ecosystemu depending on their types and ecploitation is considered. The conditions for maintaining a healthy soil ecosystem are considered, especially in organic farming systems. Options for conservation and protection of soil health, natural and induced suppressive activity of the soil ecosystem are discussed. The ways of diagnostics and therapy of soils, modern agroecosystems are described based on the developed indicators in the form of a het-erotrophic parameter of soil health and the parameter of self-sufficiency assessment of the soil ecosystem by biophilic elements.
