Object of the research - the processes of ekologic- and economic-valuable specific structure forming of agrocoenosis from long-term bob and cereal herbages at the different levels of fertilizer on the dried earths at the haying use of grass. The purpose of work consists in the exposure of the best kinds and determination of the optimum fertilizer system for highly productive meadow grass creation of the haying use on dried pottery drainage darkly-grey ashed soils of the Forest-steppe Western with the account of the system fertilizer. Methods of the researches - scientific methods of researches are inductions and deductions, analogies, generalizations and special: field supervision, laboratory, mathematically-statistical, calculation-comparative. The results of researches in dissertation work are expounded. In the case of problem decision of the proceeding in agrolandscapes by creation of highly productive plant communities of the haying use on dried pottery drainage soils natural forage lands for Western Forest-steppe.
