Rational Use of Subalpine Natural Pastures in the Central Caucasus of Georgia

Abstract

. Preserving the unique biodiversity of the highland flora established and surviving over the centuries is of greatest importance. Unsystematic use, overloading and neglect of feed-staff lands lead to reduced yields, deterioration of grassland, cord decay and development of erosive processes. Accordingly, the nutritional value of natural grassland and the quality of feed-staff obtained decreases. Surface improvement of natural meadow, one of the means used today, is an effective way to increase the yield of natural grass in the shortest possible time and improve the quality of food received. On the grassy-cereals cenosis pastures, in the grassland with predominate   of   flat-leafed bentgrass (Agrostis planifolia) and alpine timothy (Phleum alpinum L.), with the introduction of interplot grazing (against the background of fertilization) the pasture area (compared to naturally grazing) is reduced by 140% compared to naturally grazing.

By applying of N₆₀P₆₀K₆₀ to the mowing grass in the spring, an additional 12.0 kg of hay is obtained for each NPK.

On the background of fertilizers` application (N₆₀P₆₀K₆₀) on pasture grass, the grass is leveled and yield is increased, which allows an additional 7570 liters of milk or 908 kg of meat to be obtained from each hectare.
