腐殖酸理化特性及其对酸性土壤中磷有效性的影响
Humic Acid Physicochemical Properties and its Effect on the Availability of Phosphorus in Acid Soil
摘要
Abstract
The incubation experiment was conducted to evaluate the influence of different level combination of humic acid and phosphorus fertilizer on the availability of phosphorus in acid soil. The results showed that adding humic acid could significantly improve soil pH value, decrease exchangeable Al concentration, increase exchange capacity between organic matter content and cation. Humic acid application could improve soil physicochemical property, promote phosphorus availability increase, and was beneficial for phosphorus movement. As a consequence, the combination of phosphorus fertilizer and humic acid is the best choice for improvement of phosphorus availability.关键词
