Water-soluble humic acid paste-form fertilizer and its making process

Abstract

Disclosed is a grease-form water-soluble humic acid fertilizer, which comprises (by weight percent) 20-45% of weathered coal powder, 10-35% of urea, 5-15% of phosphoric ammonium, 3-25% of potassium chloride, 4-30% of potassium sulfate, 0-20% of raw material containing N, P, K, 0-5% of medium and trace element compounds, 1.0-3.55 of sodium hydroxide, 0.1-0.5% of polyacrylamide, and 15-35% of water.

Description

technical field [0001] The invention relates to a humic acid fertilizer, in particular to a water-soluble humic acid paste fertilizer and a processing method thereof. Background technique [0002] Compared with chemical fertilizers, humic acid fertilizers have obvious effects of increasing production, improving the quality of agricultural products, improving plant nutrient utilization, saving resources, reducing diseases, preventing environmental pollution caused by chemical fertilizers and pesticides from the source, improving soil, drought resistance, Excellent qualities such as cold resistance and salt-alkali resistance are gradually accepted by farmers and become an important member of the fertilizer family. [0003] When processing humic acid solid fertilizers, humic acid raw materials are often activated first to increase their water solubility. This process generally requires water as a medium to achieve. After activation, it must be dried to remove excess water, and ...

AI Technical Summary

Problems solved by technology

[0005] During the production of humic acid paste fertilizer, insoluble lumps often appear during the activation process of humic acid, which are difficult to break up when stirring, and are eventually brought into the product, resulting in uneven nutrition of the product. When farmers use it, the lumps are difficult to disperse, resulting in Inconvenient to use, farmers want to use a uniform and easily soluble paste product
