A Study Of The Energy - Performance Indicators Of A Machine - Tractor Aggregate For Vertical Mulching By Importing Organic Matter In The Soil

A special device for importing organic matter in the soil has been developed in Bulgaria for the purposes of the soil protection method of vertical mulching with ready - made compost. This device is aggregated with tractors with a nominal pulling capacity of 50 kN (John Deere 8230). The effective use of this tractor aggregate has made it necessary to perform a thorough study of some energy - performance indicators. The present article presents the results from this study. The findings prove that the selected energy - performance indicators of the aggregate for vertical mulching with ready - made compost permit its effective use and guarantee optimal pulling and speed work modes on sloping terrains of carbonate chernozems (black soil).
