Cow dung liquid fertilizer production is an efficient way to recycle manure and turn it into high-value agricultural products. The process includes six main steps: solid-liquid separation, impurity filtration, UV sterilization, anaerobic fermentation, nutrient adjustment, and final liquid fertilizer filling. Alongside liquid fertilizer making, producers can compost, crush, screen, and pelletize the separated solids to create solid cow dung fertilizer. YUSHUNXIN provides complete solutions for both liquid and solid cow dung fertilizer production, helping you maximize resource use and improve output efficiency.
Anaerobic fermentation is the core process in liquid cow dung fertilizer making. It breaks down organic matter without oxygen, producing stable, nutrient-rich fertilizer. This method improves nutrient availability and reduces harmful bacteria. YUSHUNXIN offers high-efficiency anaerobic fermentation tanks for this process. Each tank has an internal stirring system to keep the liquid evenly mixed, a built-in filter to remove residue, and an insulation layer to maintain optimal temperature. These features keep fermentation time in 72 h. During anaerobic fermentation of cattle dung, it need protein, energy, and trace elements. So, you can add beneficial fermentation microbes. Common nutrient sources include molasses, glucose, and brown sugar. Molasses is the most economical choice for liquid fertilizer suppliers, with a recommended dosage of 4%–5%.
Get SolutionIn cow dung liquid fertilizer manufacturing process, poor stability can lead to sedimentation, nutrient loss, and spoilage.
Our system uses multi-stage filtration to remove suspended solids, followed by UV sterilization to kill harmful bacteria and prevent unwanted fermentation.
In the chelation tank, you can add stabilizers, chelating agents, and pH regulators to prevent nutrient precipitation. For better nutrient retention, we recommend adding natural stabilizers (Molasses, Guar gum, Citric acid etc.) during processing.
YUSHUNXIN liquid fertilizer production machine adopts sealed structure and anti-corrosion lining to ensure the production of cow dung liquid fertilizer to the greatest extent.
In most liquid fertilizer production processes, the complete cycle takes about 3–5 days from raw material preparation to storage. Fermentation time depends on temperature, nutrient balance, and microbial activity. You can fine-tune these factors to optimize liquid fertilizer production.
In liquid fertilizer fermentation, the microbial inoculant plays a decisive role in organic matter decomposition and nutrient transformation. So you can add some beneficial agent to accelerate liquid fertilizer manufacturing process. Such as compound Bacillus, compound yeast, compound lactic acid bacteria, and compound enzyme preparations. Typically, 1 kg of microbial agent can ferment 250–500 liters of liquid fertilizer. The specific dosage depends on your raw material composition, desired fermentation speed, and nutrient requirements.

To maximize the value of cow dung, you can turn the residues from solid-liquid separation into high-quality solid cow dung fertilizer.
First, compost the separated cow dung solids. This step reduces pathogens and stabilizes nutrients.
Then use a compost crusher to break the material into fine particles. Next, screen it to remove large impurities, such as small stones or cigarette butts.
For higher profits in cow dung fertilizer manufacturing, it is an excellent choice for you to granulate the powdered compost. YUSHUNXIN offers various cow dung pelletizing machines, including disc granulators, roller extrusion compactors, and new organic fertilizer pelletizers. Finally, feed the pellets into an automatic packaging machine for efficient storage and sale.
