INFLUENCE OF DIFFERENT TILLAGE ON SOIL WATER CAPACITY

Abstract

This research examines the effects of tillage intensity and straw incorporation on soil water content. The research was conducted in a long-term stationary field experiment, which is located at the Experimental Station of the VDU Agricultural Academy. The research was continued, presented in this paper in 2023. test results. The purpose of the research is to determine the influence of different tillage on soil hydrophysical properties and spring barley crop productivity. The crop is spring barley (Hordeum vulgare L.). Agricultural crops are rotated in the following order: winter rapeseed, winter wheat, beans, spring barley. Factor - tillage systems: 1. Conventional deep plowing 23-25 cm deep, control (CP); 2. Shallow plowing with a depth of 12-14 cm (SP); 3. Deep plowing with a cultivator with boom harrows at a depth of 23-25 cm (DC); 4. Shallow plowing with plate implements at a depth of 12-14 cm (SC); 5. Direct sowing into the stubble (NT). When applying a pressure of -30 hPa in all simplified tillage systems, at all studied depths of soil layers, a trend of increasing soil moisture was observed, compared to deep plowing. However, after using -15500 hPa pressure in all soil layers, at 0-5, 5-10 and 15-20 cm, the soil moisture content decreased in all simplified tillage systems.
