From 1984 to 1987, the Eilatovsk Experimental Station in the Soviet Union conducted a study on the specific measures for how to increase the yield of 30-year long-term maize planting by periodically interrupting the continuous cropping of mature cereal crops and changing the basic soil cultivation system. The specific programs are as follows: 1 without fertilizer tillage 2 annual tillage 3 annual shallow tillage 4 year shallow tillage a year tillage; 5 year shallow tillage, three years tillage;
