The Effects of Soil Compaction and Different Tillage Systems on the Bulk Density and Moisture Content of Soil and the Yields of Winter Oilseed Rape and Cereals

Progressive soil compaction is a disadvantage of intensive tillage. Compaction exerts negative impact on the physical properties and decreases crop performance. The adverse effects can be mitigated by replacing conventional tillage with simplified techniques. Simplified protective effect soil, reduces production costs preserves agricultural ecosystems. aim this study was to determine influence different methods bulk density moisture content soil. experimental factors were as follows: Soil before sowing (non-compacted control treatment treatments where compacted after harvest preceding crop) four seedbed preparation in three-field rotation system (winter oilseed rape, winter wheat, spring barley). varied across rotated crops their developmental stages. had no significant analyzed parameters cultivation rape. In sown resulted significantly lower higher content. plots barley, led increase values both parameters. average various operations examined ranged from 1.49–1.69 g·m?3 rape), 1.47–1.59 wheat), 1.47–1.61 (spring lowest (control treatment) Regardless compaction, greatest reduction rape yields noted response skimming, harrowing absence pre-sowing plowing. Spring barley non-compacted treatments, whereas reverse observed wheat. Chisel plowing single induced decrease wheat relative Single decreased grain yield that involved skimming fall depth 25.
