Accurate ground scanning of the day surface of tilled soil to determine its agro-technical characteristics

Abstract

The aim of the research is to determine the agro-technical characteristics of the day surface of tilled soil on sloping agricultural landscapes by applying the method of accurate ground scanning along the circumference. The specific difficulties that arise in developing and implementation of agro-technical measures are often associated with significant change of the main parameters of the day surface of tilled soil depending on space and time. Agro-technical parameters according to the agro-technical requirements for the main and pre-sowing tillage, the direction and value of the average slope of the soil surface, as well as the lumpiness and cloddiness of the tilled day soil surface are determined while controlling. According to the results obtained using the developed software, it was found that the deviation angle of the projection of the line of the maximum change in height from the direction of the tillage machine movement is α=-32.4 and the slope of the studied site is 4.8 degrees. The aggregates of 1-4 centimeters in diameter are prevailing in quantity that is crumbling is ensured. The weighted average diameter of the lumps was 4.07 cm, and the standard deviation was 5.05 cm.
