Study Of The Operational Efficiency Indicators Of Soil - Protecting Machine - Tractor Aggregates Used For Vertical Mulching By Importing Organic Matter In The Soil

In Bulgaria, the soil - protection method of vertical mulching by importing organic matter in the soil can be applied by using two agricultural machines, namely a device for importing organic matter in the soil and a modified cutter-dead furrower ShtN -2-140 with a mulch hopper. The performance reliability of these machines is determined by a study of their operational efficiency indicators and the results of this study are presented in the current material. These results show that the two soil - protecting machine - tractor aggregates for vertical mulching by importing ready - made compost in the soil have good exploitation characteristics, which guarantee the timely performance of the agricultural operations on areas with various soil and terrain properties in our country.
