Abstract

Reduction of crop yield and efficiency of resource consumption are the direct and indirect adverse effects of soil compaction, which affect the profitability of agricultural systems. Soil compaction impresses the structure of the soil by reducing air-filled porosity, increasing soil bulk density and mechanical resistance and reducing total porosity. The present review article has been carried out to evaluate the various studies conducted regarding the effect of different tillage systems on soil compaction and its influence on yield and economic value of land. Studies show that between 70-80% of soil compaction occurs during the first passage of agricultural machinery on land and the decrease in crop yield due to soil compaction in various researches has been reported in the range of 5-75%. In a study, the average financial losses due to soil compaction of agricultural land in Ukraine and Lithuania were predicted to be 49 and 13 euros per hectare per year, respectively. The financial cost of soil compaction caused by spreading liquid fertilizer with a heavy tanker weighing more than 18 Mg and a pressure of more than 200 kPa on wet soil in early spring in Canada was also estimated at 30 to 300 dollars per hectare and the increase in the load on the wheels of agricultural machines from 1 MPa to 9 MPa in Sweden, reduced the net income of agricultural land by 25%. Studies show that the use of a No-Tillage system leads to economic savings, increased energy efficiency, and reduced greenhouse gas emissions, and in most cases, it leads to an increase in crop yield per unit of area.
