Grow cover crops when the field is empty Soil Fertility

A randomized, replicated, controlled experiment between October 1998 and July 2001 on silty-clay soil in Samsun, eastern Turkey (Gülser 2006) found improved soil structure, increased soil organic carbon content between 1 and 37%, and reduced soil penetration resistance between 15 and 36% under forage (animal feed) cropping, relative to unplanted fallow controls. Bromegrass Bromus inermis was the most effective forage and perennial ryegrass Lolium perenne the least. After autumn ploughing (to 15 cm depth) and rototilling, perennial ryegrass, bromegrass, alfalfa Medicago sativa, small burnet Sanguisorba minor, subterranean clover Trifolium subterraneum and purple crownvetch Coronilla varia forage treatments were established and compared with unplanted fallow controls. Forages were grown on three 2 × 5 m plots and seeded in rows 40 cm apart. Soil characteristics were measured on samples taken from the top 15 cm of soil.
