Comparative Research on Advanced Technologies for Minimum and Unconventional Soil Tillage with Application of Different Mulching Materials for Growing Wheat on Sloping Agricultural Lands

In the Republic of Bulgaria a significant part of the arable lands are on sloping terrains, which is a prerequisite for the influence of the degradation processes soil water erosion, compaction and loss of the soil organic matter. For their limitation, advanced soil protection technologies have been developed and studied, including technological processes surface and vertical (into the soil) mulching with the application of mulch materials compost and manure. The present research explores the results of long-term comparative studies with these technologies for growing wheat on slope areas in specific soil and climatic conditions and evaluates their agro technical and soil protection capabilities.
