THE SОIL FERTILITY OF THE RECLAIMED LAND IN THE LVIV REGION
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 6, Issue 6
Abstract
The development of agriculture depends on effective use and conservation of land resource. The soil is the main means of growing agricultural products. Its main characteristic is fertility, which manifests itself in crop yields. Fertility provides plants with powerful supply of the water, air and favourable physico-chemical environment for normal growth and development. Therefore, for the development of the agrarian sphere it is necessary to increase the soil fertility, to promote the rational use of land resources. Appropriate and needed transition from the economic principles of nature usage development to the agreed ecological and economic bases of activity. Necessary preservation and restoration of the soil fertility in Ukraine. Soil fertility as well as yield depends not only on the natural fertility of the soil, but from their use and the culture of farming. Nowadays the soils are depleted due to non-observance of scientifically grounded crop rotation and technologies of soil cultivation, the decline of agriculture culture, the decrease in the volume of replenishment of mineral and organic fertilizers, development of the water erosion. Significant changes have taken place on the reclaimed lands. This is the evaluation of the changes of the reclaimed land soil fertility that this work is dedicated to in the Lviv region during 1998-2017. The evaluation is fulfiled with the help such indicators, as groundwater levels, humus content, acidity, the degree of saturation with the bases, the content of digestible nitrogen, mobile phosphorus, mobile potassium, mobile manganese, the degree of decomposition of the peat. It is also evaluated reclamation and ecological state of the drained lands in the Lviv regionas well as stated that the favourable reclamation state for the crop cultivation is 14.7% (from 513,2 thousand hectares of the drained lands), and ir is steadily deteriorating every year. Also, the indicators of the fertility and environmental sustainability of the soils are declining. According to these indicators, the spatial analysis of soil distribution has been carried out and territories have been defined, which are unsuitable for the crop cultivation.
