Increasing the bioproductivity of salted and erosionally dangerous land of the Donetsk region by almonding

Abstract

A survey of the soil cover and the state of natural grass cover of saline and erosively dangerous lands of the valley and the beam system of the Sukha Yali River was carried out. Low-productive saline lands are located on the slopes and bottoms of beams, micro-lowering of lower and floodplain meadows. Plant communities confined to such soils are characterized by low species richness and poverty of fodder valuable species. The results of research on the improvement of unproductive lands on saline soils by sowing a set of forage grasses that are able to grow in conditions of soil salinity and have a high forage value are presented. It was found that during the observation period the yield of green mass and hay in all variants was much higher than the yield of natural grass. The biochemical composition of forage grasses is characterized by an increased content of crude protein, carbohydrates, vitamin C and essential amino acids. The data on the introduction of honey grasses for the improvement of saline forage lands in the complex with wild honeysuckles are given, their nectariness is determined. Bioagronomic evaluation of forage plants growing on chernozem salt marsh was carried out. Recommendations for the improvement of forage lands on saline and saline soils are given.
