Abstract

See full text

The present invention relates to a method for preparing a humic acid-containing synergistic carrier for accelerating urea conversion. The preparation method includes steps of, for example, preparing an extractant for humic acid, preparing a humic acid extract and preparing a humic acid-containing synergistic carrier. Combination of the humic acid-containing synergistic carrier with urea can accelerate urea conversion, and the residual urea rate will be reduced by 22.7%-29.1% than a commercially available urea. The present invention provides a new idea for improving the utilization rate of nitrogen fertilizer in soil with low urease activity. Compared with a commercially available urea, the urea containing the humic acid-containing synergistic carrier of the present invention can increase the rice yield and the utilization rate of nitrogen fertilizer by 9.7% and 8.3%, respectively.
