Abstract
The consequences of water erosion processes in arable lands are reduction of the root layer, deterioration of soil structure, lower water retention capacity of the soil and loss of nutrients and organic matter, and final result, reduction of soil fertility. To combat water erosion on slope lands were created advanced systems for minimum and unconventional tillage for cultivation of maize on slope lands. This study examines the economic efficiency of these systems, included the impact of these treatments on the yield of crops and their conservation effect.
Highlights
The consequences of the degradation processes on water erosion and the loss of soil organic matter are of great importance for the economic life, and the damages caused by them are enormous, which necessitates the application of a system of erosion control measures
In ISSAPP "Nikola Pushkarov" - Sofia, in cooperation with the Ruse University "Angel Kanchev", there are designed and developed advanced systems for minimum and unconventional soil tillage, to limit the degradation processes in the cultivation of maize and wheat on sloping agricultural lands
The aim of the present work is to establish the economic efficiency of the advanced soil protection technologies for minimum and unconventional soil tillage for maize production on sloping agricultural lands on the basis of the obtained experimental results
Summary
Of the whole complex of erosion control measures (practices), the most important for the protection of the agricultural lands from the soil water erosion are the agrotechnological ones, carried out with the help of various erosion control technological processes, methods and technologies Their advantages are low cost, easy implementation and reduction of hydro-erosion processes as soon as they are applied [2, 3]. For these reasons, in ISSAPP "Nikola Pushkarov" - Sofia, in cooperation with the Ruse University "Angel Kanchev", there are designed and developed advanced systems for minimum and unconventional soil tillage (soil protection technologies for minimum soil tillage with the inclusion of technological operation vertical and surface mulching with compost), to limit the degradation processes (water erosion and loss of organic matter) in the cultivation of maize and wheat on sloping agricultural lands. The aim of the present work is to establish the economic efficiency of the advanced soil protection technologies for minimum and unconventional soil tillage for maize production on sloping agricultural lands on the basis of the obtained experimental results
