NITROGEN AND HEAVY METAL UPTAKE BY FIELD CORN FROM PROCESSED SPENT ACIDS.BUDZYNSKI, JAMES WILLIAM. January 1982 (has links)
Plots of field corn established in Michigan and Arizona were fertilized with two industrial wastes of nitric acid as nitrogen fertilizers. Major contaminants before processing (greater than 1000 mg/l) were Cu, Pb, Ti, Zn, and Zr. Of these, only Cu and Zn were present in significant quantities after neutralization with ammonium hydroxide. Application rates of 0, 67, 135, and 202 kg N/ ha were used, and compared with commercial ammonium nitrate fertilizer at 202 kg N/ ha. No significant differences were found in Pb, Zr, and Ti concentrations in corn tissue or grain due to treatments. Higher Cu and Zn levels occurred in plants from plots receiving the spent acids, but the concentrations were not significantly different from those found using commercial ammonium nitrate. No significant differences were found in corn grain Cu and Zn levels due to treatments.
