Theoretical regulations of agricultural ecology and their practical implementation

Provisions are made about the predictive functions of quality and quantity of energy in the environment. The basic properties of the environment are given: its inertness and stability as a reaction to the influence of disturbing factors. As examples, the determining trends of plant productivity changes are shown depending on the quantitative parameters of the acting factors. It is proposed to use for optimization the norms of factors corresponding to the coordinates of the inflexion point in the curvilinear trends of the change in productivity. Affirms the possibility of changing the elastic stability by directing the impact on individual factors by optimizing technological methods and/or using certain means of running a particular agricultural sector. The possibility of changing resistance by selection has been substantiated.
