How to use cow dung to make liquid fertilizer

In addition to making solid waste from cow dung, you can also choose to use cow dung to make liquid fertilizer. To this end, we LANE can provide you with customized cow dung liquid fertilizer production line solutions and mechanical equipment for production.

6 steps to make liquid fertilizer from cow dung:

Generally speaking, 6 steps are required to process cow dung into high-quality liquid organic fertilizer.

Collecting fresh cow dung for making liquid fertilizer

Generally, the production of high-quality liquid water-soluble fertilizer begins with collecting fresh cow dung. Using fresh cow dung is crucial because fresh cow dung contains higher concentrations of nutrients and beneficial microorganisms than old dry cow dung,

Filtration of fertilizer production liquid

It contains 2 parts. First, the solid cow dung is removed from the liquid. Here, you can use a manure solid-liquid separator. On the other hand, small particles are filtered from the liquid raw manure material. Therefore, you can produce water-soluble fertilizer that is easier to use. Here, our engineers use activated carbon filtration design.

UV sterilization

Then harmful pathogens, viruses, fungi, etc. can be eliminated to ensure the safety of the liquid fertilizer produced. As the name implies, our cow dung liquid fertilizer production system uses ultraviolet sterilization technology. Its pathogen elimination rate can reach 99%.

Add auxiliary materials to improve the nutrient content of the final liquid fertilizer

If you want to add some NPK, MSI elements to increase the nutrient content, or add molasses or fermentation agents to accelerate the fermentation of liquid fertilizer, there are batching tanks for you to use. Mix the additives with water, and the batching tank will send it to the wave state cow dung fermentation according to the required proportion.

Blending and fermentation of liquid cow dung fertilizer

For the production of liquid fertilizer from cow dung, fermentation is important. Similar to solid cow dung fertilizer production, this is a harmless process for wave state fertilizer. Through the mixing of the stainless steel liquid fertilizer reactor, enzymatic hydrolysis will occur, breaking down the nutrients into smaller molecules and further eliminating harmful pathogens in the material.

Cow dung liquid fertilizer packaging

Finally, for commercial liquid fertilizer production, you need to package the finished cow dung fertilizer. For this, the automatic liquid filling machine is the best choice. It can complete the filling, summer capping, labeling, etc. of liquid fertilizer.

Can we make liquid fertilizer from dry cow dung?

Of course. To process dry cow dung into liquid fertilizer, it is best to add water before the liquid fertilizer fermentation. Here, Yushuxin can provide you with reverse osmosis equipment to provide high-purity water for the manufacture of cow dung liquid fertilizer. It can purify municipal tap water, uncontaminated groundwater or surface water and lake water. Generally speaking, the ideal production process of dry cow dung liquid fertilizer is cow dung crusher → reverse osmosis equipment (add water) → fermentation → liquid reactor → solid filter → liquid filling equipment

How long does it take to ferment cow dung to make liquid fertilizer?

Usually, the fermentation time of cow dung liquid fertilizer depends on the method used.

Using enzymes to decompose cow dung slurry for anaerobic fermentation, it only takes 3-7 days.

As for aerobic fermentation of bacterial hydrolysis, it usually takes 15-25 days.
