Synopsis Application of 2.5 pounds of Cu per acre corrected the deficiency on both high and low organic matter soils. Applications made at planting on February 15 or March 15 were equally effective where the deficiency was not severe; but on soils with severe deficiency applications after February 15 did not give maximum yields. Three common Cu compounds gave similar results. Cu level in the plant was not affected greatly by the rate but was affected by date of application of Cu and by other micronutrients.
