英文摘要 | Two extractants, 0.01 M CaCl2 and 0.01 M Ca(H2PO4)(2), and two incubation systems, closed and open, were used to investigate the influence of granule dispersion and granule size on SO42- formation in a Red soil treated with a new micronized, granular S-0 fertilizer at rates of 500 and 3000 mg kg(-1) of S-0. Sulfate production was significantly greater with dispersed micronized particles than for either the 1 to 2 mm or 2 to 4 mm intact granule size fractions. Increasing the dosage of S-0 resulted in much greater SO42- formation from all particle sizes of S-0. Quantities of SO42- extracted by 0.01 M Ca(H2PO4)(2) generally exceeded those removed by 0.01 M CaCl2 in both the closed and open incubation systems. Levels of extractable SO42- recovered in the open incubation procedure were consistently much greater than those in closed incubation. In open incubation, extractable SO42- varied from 0.66 to 36.79 mg S/100 g soil and 1.35 to 65.02 mg S/100 g soil, respectively, for the 0.01 M CaCl2 and 0.01 M Ca(H2PO4)(2) leaching solutions. With closed incubation, SO42- recoveries ranged from 0.15 to 12.08 mg S/100 g soil and 0.21 to 31.74 mg S/100 g soil in the 0.01 M CaCl2 and 0.01 M Ca(H2PO4)(2) extracts, respectively. The average oxidation percentages measured by 0.01 M Ca(H2PO4)(2) extraction were 27.9%, and 36.7% greater than those occurring with 0.01 M CaCl2 extraction, in closed and open incubation, respectively. Oxidation percentages for the dispersed S-0 particles were significantly higher than for intact fertilizer S-0 granules, which increased significantly with decreasing granule size. Oxidation percentages were significantly greater at the lower dosage rate of S-0 fertilizer. Highly significant linear function relationships between cumulative SO42- formed by oxidation of S-0 and the time of open incubation were found. |
