What additives are commonly used in liquid fertilizer making?

Liquid fertilizer production often requires precise use of additives to improve efficiency, stability, and nutrient content. Here are the main categories for their application.

Adding The Fermentation additives to speed up liquid fertilizer production

Fermentation additives help create a stable microbial environment and shorten the production cycle. You can add molasses, amino acids, enzymes, or yeast extract to supply nutrients and enhance microbial activity. Typical dosage is 0.5–1% of the total liquid volume. Mix the additive with warm water and introduce it at the beginning of fermentation to maximize effectiveness.

Anti-Settling Agents to Prevent Sediment

How to prevent liquid fertilizer from settling? This is a common problem for many liquid fertilizer manufaturers. So, you can add Anti-settling agents maintain a uniform liquid. You can use polyacrylamide, bentonite, or clay-based stabilizers. Typically, add 0.2–0.5% of the total liquid volume during the final chelation stage, after primary fermentation.

Microbial Inoculants for producing liquid bio fertilizer

In the liquid fertilizer manufacturing process, you can also add microbial strains to meet specific market demands.

  • For example, Bacillus subtilis, Lactobacillus, or other plant-growth-promoting bacteria. Add 0.1–0.3% of the total liquid volume. Typically, 1 kg of microbial inoculant is sufficient for 500–1000 kg of liquid fertilizer. Introduce the microbes after the fermentation cools down to protect their activity. Use a sterile mixing tank with gentle agitation to prepare the solution, then add it evenly into the main liquid fertilizer tank for consistent microbial distribution.

The additive dosing tank used in liquid fertilizer making company:

For precise additive application, we recommend YUSHUNXIN’s additive dosing tanks with built-in agitators. They ensure uniform mixing of fermentation promoters, anti-settling agents, and microbial inoculants. The integrated dosing pumps deliver additives accurately into the main liquid fertilizer tank. At the same time, all equipment is made of stainless steel, providing strong corrosion resistance and long service life. YUSHUNXIN can provide you with different specifications of ingredient adding tanks, welcome to consult. Such as 1 m³,3m³,5m³.
