Fertility Management of Winter Wheat Grown after Alfalfa
Forage hay crops remove large amounts of nutrients from the soil, because of this, levels of available phosphorous, potassium and sulfur are often marginal for crops following forages.

1997 Annual Interpretive Summary
Fertility Management of Winter Wheat Grown after Alfalfa, 1997
Alfalfa breaking is often deficient in N, P and K because of the high nutrient demand of alfalfa. This project is investigating the fertility requirements of winter wheat seeded on alfalfa breaking. Initial results show that a combination of alfalfa in rotation with N fertilizer provides higher protein that either alfalfa or N alone. The effect of Cl on yield and suppression of leaf spotting is also being evaluated but Cl did not have any effect this year. MB-10
