Abstract. The article suggests a bioenergetical anal-ysis of energy content in humus of grey forest soil de-pending on its fractionally grouped structure. It presents culculations of energetic efficiency of applying mineral, organic and organically – mineral systems of fertilizing jerusalem artichokes, in particular with including multi-functional preparation of phylazonit. The research de-termines efficiency of applying agrocenosis of the gross energetic resource .
Key words: system of fertiliazation, humus, bioener-getical analysis, coefficients of energetical efficiency.
