Nagirnyak T. Perection of agrotechnical measures of increase of degenerated grass stands of hayfield and pastures productivity in conditions of western Forest-Steppe

Object of research: process of renovation of degenerated meadow-pasture lands by dint of direct sowing of bean components into an untouched sod attached to use of mineral fertilizing, herbicide, liquid manure and nitrogenizator. Purpose of research: elaboration and theoretical basis of rational differentiated energy and resources saving technology. Methods of research: field in a combination with visual and by supervisions, measuring-gravimetric, electrophotometry, laboratory-analytic, mathematical-statistic, calculation-comparative. Theoretical results and novelty: For conditions of western Forest-steppe elaborated a new complex of agrotechnical measures of renovation of degenerated grass stands. Expressed effectiveness and set influence of direct strip sowing of bean grasses with help of aggregate LUKA-2,8 in combination with soil applying of liquid manure, mineral fertilizing and nitrogenizator on hayfield and sowing of bean components by different wide cut of sod of degenerated pasture in combination with applying of full mineral fertilizing and different norms and stripes raundap on productivity of improved meadows, botanical, biochemical composition of grass stand and quality of fodder, accumulation mass of roots, microbiological activity of soil and balance of nutriments. Given economic and bioenergetic estimation to elaborated technological measures. Practical results: elaborated principled new scientifically substantiated practical recommendations for production on inculcation on natural fodder lands energy and resources saving technology of renovation of degenerated grass stands by the help of sowing of perennial bean grasses into being degradated grass stand with simultaneous loosening of soil, applying of organic and mineral fertilizers into sod and application of herbicide and nitrogenizator on mineral soils of western Forest-steppe. Sphere of use: agricultural forming of different forms of property, in which in stock in structure of earths there are lands under degenerated hayfields and pastures for fast their transformation into highly productive; educational programs of agrarian higher educational establishments 3-4 level of accreditation.
