These costs do not account for the loss of long-term sustainability of the land. Major soil associations in Prince Edward Island have potential rooting depths of only 25 to 40 cm (10 to 16 in). The impact of soil erosion is critical on such shallow soils. Methods to reduce soil erosion are required. This study investigated the benefits of residue management and the retention of surface dead plant material in a 2-yr grain/potato rotation and a 3-yr grain/forage/potato rotation. Residue management in the 2-yr rotation reduced soil erosion as estimated by rainfall simulation by as much as 50% and tuber yields were not affected. Residue management reduced soil erosion up to 90% in the 3-yr rotation and tuber yields were improved by 7%. Tillage costs were reduced by $60 to $160 per ha ($25 to $64 per ac) using residue management with an average savings of $100 per ha ($40 per ac). Residue management uses new tillage practices and may require modifications to planters and harvesters to accommodate the increased plant residue. %U https://www.jswconline.org/content/jswc/54/1/445.full.pdf
