How to Make Liquid Fertilizer from Cow Dung

Collect Fresh Cow Dung for liquid fertilizer making

Usually, quality liquid water-soluble fertilizer manufacturing starts by collecting fresh cow dung. It’s essential to use fresh dung because it contains a higher concentration of nutrients and beneficial microorganisms compared to older, dried dung.

Filter liquid for fertilizer production

It contains 2 parts. For one thing, removing solid cow manure from the liquid. Here, you can use a manure solid and liquid separator. For another, filtering small particles from liquid cow manure material. So, you can produce water soluble fertilizer which is easier to use. Here, our engineer adopts activated carbon filtering design.

UV Sterilization

Then in order to eliminate harmful pathogens, viruses, fungi, etc to ensure the safety of produced liquid fertilizers. As the name suggests, our system to make liquid fertilizer from cow dung adopts UV sterilization technology. Its pathogens elimination rate can reach 99%.

Auxiliary material adding to improve nutrient content of final liquid fertilizer

If you want to add some NPK, trace elements to improve nutrient content or molasses or fermentation agent to speed up the liquid fertilizer fermentation, there is batching tank for you. Mixing additives with water, the batching tank will send then to liquid cow manure fermentor according to required proportions.

Liquid cow manure fertilizer mixing and fermentation

For producing liquid fertilizer from cow dung, fermentation is important. Similar with solid cow manure fertilizer production, it is a harmless process of liquid fertilizer. With stainless steel liquid fertilizer reactor mixing, enzymatic hydrolysis will take place to decompose nutrient substances into smaller molecules and further eliminate harmful pathogens in materials.

Cow manure liquid fertilizer packing

Finally, for commercial liquid fertilizer production, you need to packing finished cow manure fertilizer. For this, automatic liquid filling machine is the best choice. It can finish liquid fertilizer filling, covering, labeling, etc.

Of course. To processing dry cow manure into liquid fertilizer, it is advisable to add water before liquid fertilizer fermentation. Here, YUSHUXIN can provide you with reverse osmosis equipment, which can offer high-purity water for cow manure liquid fertilizer manufacturing. It can purify municipal tap water, non polluting groundwater or surface water and lake water.

• For makes use of enzymes to decompose cow manure slurry liquid, the anaerobic fermentation, it needs only 3-7 days.
• As for aerobic fermentation with bacterial hydrolysis, it usually take you 15-25 days.
