| Abstract/Contents: | "Fertilizer-use efficiency of NH4+ and K+ can be low in soils that absorb these ions in a nonexchangeable form. In a laboratory study, the soil adsorption interactions resulting from simultaneous proximal injection of anhydrous NH3 (AA) and KCl solution were investigated to determine if such interactions might have an effect on the availability of these nutrients. The fertilizers were injected separately and simultaneously into two soils, a Hoytville silt clay loam (fine, illitic, mesic Mollic Ochraqualf) and an Avonburg silt loam (fine-silty, mixed, mesic Aeric Fragiaqualf). Following incubation for periods of 1, 7, 14, 28, and 84 d at 20 °C, soil in the injected-fertilizer bands was sampled from four concentric zones of radii 0 to 2.0, 2.0 to 3.0, 3.0 to 4.5, and 4.5 to 6.0 cm around the injection point. In the Avonburg soil, very little interaction between the two fertilizer materials was observed. In the Hoytville soil, simultaneous injection of AA and KCl had little effect on NH4+ distribution, compared with AA injection alone. Relative to KCl injected alone, simultaneous injection of AA and KCl in the Hoytville soil increased exchangeable K+ and decreased fixed K+ within 3.0 cm of the injection point. The effect on fixed K+ persisted throughout 84 d of incubation, while the effect of exchangeable K+ was not apparent beyond 28 d of incubation. Decreased K+ fixation was attributed to preferential NH4+ fixation blocking K+ fixation. Increased exchangeable K+ was attributed to pH-induced increases in cation-exchange capacity (primarily in the organic fraction), and to decreased K+ fixation." |
