Water-soluble fertilizers are liquid or solid fertilizers that are dissolved or diluted in water and used for irrigation, foliar fertilization, soilless cultivation, seed soaking and root dipping.

As a multi-nutrient fertilizer, water-soluble fertilizers can be quickly dissolved in water and are more easily absorbed by crops. Moreover, their absorption and utilization rate is relatively high, which can meet the nutritional needs of high-yield crops during the rapid growth period. Especially in facility agriculture, it is combined with micro-sprinkler irrigation and drip irrigation. With the increasing shortage of water resources today, the application of water-soluble fertilizers has become one of the measures to increase agricultural efficiency and farmers' income.

The title of this paper is "Application of Polyaspartic Acid in Water-soluble Fertilizers". It studies the current status of water-soluble fertilizer application in my country and systematically analyzes polyaspartic acid, pointing out the possible application direction of polyaspartic acid in water-soluble fertilizers.

Abstract：The application status of water soluble fertilizer in China was studied in this paper. The scaling，corrosion，soil problems in the application of water soluble fertilizer and its influence on the integration of water and fertilizer were analyzed. The effects of Polyaspartic acid had been also systematically analyzed in the aspects of enhancing the chelation and dispersion of chemical fertilizers，reducing the corrosion of fertilizers to pipelines，increasing production and improving quality，and its environmental protection characteristics. It is considered that the application of Polyaspartic acid in water-soluble fertilizer has both opportunities and problems. At the end of the article，the author points out the possible application direction of Polyaspartic acid in water-soluble fertilizer.
