| 英文摘要 | An investigation was conducted to study effects of the potassium and ammonium saturated clinoptilolite on p availability in ferrosols. the adsorption and desorption of phosphorus were determined by shaking 2.5 g soil with 0, 0.5, and 2.5 g clinoptilolite at 0.31 or 1.25 mg p/g soil in 50ml solution for a total of 72 h ( 24 h for clinoptilolite and 48 h for phosphate). the nutrient concentrations in supernatants were measured by spectrophotometry. results showed phosphorus solubility was significantly increased with clinoptilolite addition. increasing the amount of clinoptilolite enhanced the concentration of p up to 6.85 and 41.29 mg/ l at 0.31 and 1.25 mg p/g soil, respectively. correspondingly, the amount of potassium and ammonium released from the clinoptilolite were up to 63.69 and 12.20 mg/l at 0.31 mg p/g soil, and 107.42 and 29.94 mg/l at 1.25 mg p/g soil. nutrient concentrations in the treatments in which clinoptilolite was added before p were greater than that in the treatments in which p was added prior to clinoptilolite. the results also suggest that potassium and ammonium saturated clinoptilolite can increase p solubility while providing k and nh4 to the soil, a concurrent positive effect for plant growth. |
