The productivity and fodder value of herbal phytocenosesand their influence on agrophysical characteristics of leached chernozem in Krasnoyarsk forest-steppe

The research objective was to define the efficiency and quality of herbal phytocenosis and their influence on agrophysical properties of the soil. The studies were conducted on leached chernozem experimental ground of Krasnoyarsk SAU in 2014- 2015. The experiment scheme was represented by galega (Galaga orientalis) varieties Gornoaltayskaya-87 (2013-2014), annual clover (Melilótus alba) variety Volga, red fescue (Festuca rubra L.) cultivars Diana, payza (Echinóchloa frumentáce) of Eureka variety, by hybrid alfalfa (Medicago media) of the variety VEGA used as a standard. Collecting green and dry material, the maintenance of digestible protein and fodder units, an exit of exchange energy, and also the content of sugars and crude protein in solid were taken into account. In 2015-2016 in clover and payza agrophysical properties of the soil were not determined, but were installed in soil under crops of hybrid alfalfa (Medicago media) of VEGA variety. The seeding of perennial grasses was carried out in 2002 (Galega orientalis) and 2006 (Medicago media)...
