This shows that a soil structural condition under the stands of these crops is good and excellent. Herewith, a positive effect of liming on agronomically valuable aggregates content is noted. Thus, in the experiment, the largest number of agronomically valuable aggregates in soil – 85,5 % (the soil structural condition is excellent), is determined when using grass mixture of alfalfa with meadow clover and Hungarian brome (smooth brome) on the slope of north-east exposition. The soil agrochemical status slightly differs among the various usage modes of the site and its geographic location; however, a trend is established to insignificant accumulation of phosphorus mobile forms under miscanthus. It is established, that the energetic crops increase the indicators of actual acidity when sowing perennial grasses on the contrary acidifies the soil solution. The highest humus content is established on control fallow areas. The soil on all the field trial sites has been characterized by better physical-chemical indicators on the southern slope. In our research, washing away the soil on the sediment and perennial grasses of the fourth year of usage was absent. However, under miscanthus and especially under oat, the soil did not have such a high resistance to erosion. Thus, during heavy rain, washing away the soil on miscanthus made 0,6 m3/hа, and on oat – 3,6 m3/hа. More favorable conditions for perennial grasses- and bioenergetics crops high yield have formed on the slope of northeastern exposition, compared to the southwestern one. The most productive in conditions of carrying out the experiment proved to be the grass mixture of alfalfa, meadow clover, and smooth brome. Fertilization has been one of the main factors of increasing perennial grass stands productivity on both slopes. Product Description popup.authors popup.nrat_date 2021-01-25 Close
