Scientific Substantiation of Introduction of Differentiated Agricultural Systems, Increase of Productivity of Agricultural Production
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 2, Issue 3
Abstract
To solve various practical issues and, first of all, the most rational placement of crops and increase their yield, it is necessary to assess the soil, taking into account their quality and its change under the influence of production activities of farms. To this end, the soils of the natural zones common in the territory of the object were studied. Their assessment was carried out from the basis of agrochemical and water-physical properties of soils, the degree of their erosion and crop yields. The soils of the agricultural zone were estimated for humus, nitrogen, phosphorus, absorption capacity and some water-physical properties in 0-2 cm, 0-50cm and 0-100cm soil layers. The scientifically based allocation of land, a differentiated system of farming, conducted on the basis of estimates, makes it possible to improve the productivity of agricultural crops. Among the soils of the agricultural zone, according to the indices of natural fertility, the undisturbed mountain-brown steppe soils were the highest. Which are accepted as a “standard”. Points of other soils common in these zones are also calculated as a percentage of the standard. In order to rationally combine and group the soils that are part of the agricultural zone and are intensively used in agricultural production, they are grouped into five groups: lands of the best, good, medium, low and very low dignity. A rather fractional grouping of soils is based on objective indicators of soil fertility and their productivity. At the same time, the grouping, based on the community of lands, allows rational and purposeful use of soils from an agricultural point of view. Below we dwell on the agroproduction characteristics of the selected groups. The group is the land of the best dignity. This group includes undisturbed mountainbrown steppe soils, the area of which is 9565.0 hectares or 23.89% of the total area of the agricultural zone, with scores of 81. The reserves of humus, gross nitrogen, total phosphorus and absorption capacity in 0-20cm soil layers is 124.11t/ha; 7.23t/ ha; 6.21t/ha and 38.87mg/eq per 100g of soil, in 0-50cm layers, respectively, 223.42t/ha; 15.41t/ha; 12.62t/ha and 38.17mg/eq per 100g of soil, and in 0-100cm layers 327.32t/ha; 18.26t/ha; 17.65t/ha and 41.23mg/eq per 100g of soil. For the soils of this group, special anti-erosion measures were not required. In order to maintain the natural fertility of these soils, planting of vineyards, plowing, sowing and tillage should be done across the slope, observe erosion and agro technical measures. YY group is a land of good dignity. The area of these lands is 13783.5 hectares or 11.24% of the total area of the agricultural zone. They are estimated in the range from 61 to 80 points on a bonitet scale.
