Comparison of the effectiveness of chelated and inorganic micronutrient fertilizers for foliar application
Six field expts. with winter wheat were carried out to compare the fertilizer efficiency of Cu and Zn sulfates or chelates citrates applied as foliar sprays. The metal concns. in the grain was detd. The chelated Cu showed higher efficiency than CuSO4. The efficiency of Zn was lower than that of Cu and did not depend on its form.
