Deep plowing

Deep plowing is a plowing to a depth greater than 50 cm (20 in) as compared to ordinary plowing which rarely exceeds 20 cm (8 in). The purpose of deep plowing is to modify the soil water retention characteristics over the long term. In one long term test, lasting 35 years, the mean annual grain yield was 2,800 lbs per acre (3,138 kg per ha) with deep plowing, which was 10% greater than the 2,550 lbs per acre (2,858 kg per ha) yield in unplowed plots.
