Abstract
Abstract Movement of Zn in Hartsells fine sandy loam (pH 5.2) from granules containing 2% Zn as 65 Zn labeled ZnSO 4 decreased in the order: ammonium nitrate (AN) > soil (no carrier) = concentrated superphosphate (CSP) > monoammonium phosphate (MAP) = triammonium pyrophosphate (TPP). In limed soil (pH 7.1) Zn movement was less from MAP than from all other carriers, and Zn movement from each carrier was less than that in acid soil. Zinc also moved further from MAP than TPP in other soil systems below pH 6.0, the same between pH 6.0 and 6.8, and less above this range. Most Zn movement from P carriers occurred during the first week, except in extremely acid soil. Carrier‐Zn reactions affected the amount of Zn which moved out of the fertilizer granules, but soil‐Zn reactions were also important in affecting Zn movement from the granule site. The recovery by various chemical extractants of Zn applied in granules of soil and in all macro‐nutrient carriers to acid soils was similar. The amount of Zn recovered by 2N MgCl 2 from limed soil less than 0.5 cm from the granule varied with carrier after 1 week, but was similar for all carriers after 8 weeks. Uptake of Zn by corn ( Zea mays L.) in a greenhouse pot experiment was greater from AN, but no clear relationship was evident with the P carriers.
