Abstract

Abstract A field experiment was conducted to study the influence of soil pH micronutrient additions and other management practices on soybean yields where peach trees had been grown previously. Decreased soybean yields resulted when either zinc sulfate or superphosphate was added to soil with a pH value below approximately 5.40. FeEDDHA improved plant growth, but did not influence soybean yields. Raising soil pH from 5.40 to approximately 6.40 with 2,602 kg/ha of dolomitic limestone increased plant growth and soybean yields. Zinc content of leaves ranged from a high of 229 ppm in acid soil to 77 ppm in limed soil. Highest soybean yields were obtained from organic matter (snap corn meal) in combination with dolomitic limestone.
