How Will Conversion to Organic Cereal Production Affect Carbon Stocks in Swedish Agricultural Soilsiculture. Other crops were not considered due to difficulties in large-scale cropping of oilseed rape and potatoes organically because of pest problems. Four scenarios were used: 0, 8 (current), 20 and 100% organic cereal production.
