Functions Of Humic Acid Water Soluble Fertilizer

1. Humic acid water soluble fertilizer can improve nitrogen fertilizer utilization rate: Nitrogen fertilizer is an indispensable fertilizer for plant growth, mainly urea and carbamide. When urea and carbamide are applied to the soil, they will quickly lose with air and water flow, and the nitrogen element nutrients that crops can truly absorb and utilize are only 30%. The acidic functional groups such as aromatic nuclei, hydroxyl groups, and carboxyl groups in humic acid can react with nitrogen elements to form stable new ion groups. These complexes remain in the soil for a relatively long time and gradually decompose to release nitrogen elements, allowing plants to slowly absorb them.

2. Humic acid water soluble fertilizer has synergistic effect on phosphorus fertilizer: After applying rapid phosphorus fertilizer to the soil, the phosphorus element is fixed by metal ions in the soil, causing rapid phosphorus to be converted into delayed or ineffective phosphorus. The acidic functional groups such as aromatic nuclei, hydroxyl groups, and carboxyl groups in humic acid can react with phosphorus, making it soluble phosphorus. This increases the activity of phosphorus and makes it easy for plants to absorb it. According to statistics, after adding humic acid fertilizer, the fertilizer efficiency of phosphorus fertilizer can be relatively improved by 5-10%.

3. Humic acid water soluble fertilizer has a synergistic effect on potassium fertilizer: the functional groups in humic acid can also absorb and store potassium ions, which can prevent potassium ions from losing with water in sandy soil and prevent potassium fixation in cohesive soil, and can improve the utilization rate of potassium fertilizer by about 5%.

4. Humic acid water soluble fertilizer has the function of water and fertilizer conservation: humic acid interacts with calcium ions in the soil to form flocculent gel, which can cement the soil together, making the soil particles become small reservoirs and fertilizer reservoirs for water and fertilizer conservation, increasing the soil voids, thus improving the ability of soil water and fertilizer conservation.
