In organic fertilizer production, the quality of raw materials directly determines the final product’s performance. So, how do you pick the best raw materials for your organic fertilizer production line?  

1. Types of Raw Materials

Animal-based materials:  

Chicken manure: Opt for waste from large-scale, modern poultry farms. These facilities typically manage manure properly, ensuring stable levels of nutrients like nitrogen (N), phosphorus (P), and potassium (K). Healthy chicken flocks also reduce the risk of harmful pathogens.  

Cow manure: Prioritize manure from cattle raised on natural pastures with fresh grass diets. This type of manure is rich in organic matter and fiber, which helps improve soil structure. 

Plant-based materials:

Crop straw (such as wheat, corn): Choose dry, mold-free straw. Dry straw resists harmful bacteria during fermentation and breaks down better into humus.  

Oilseed meal (such as soybean meal): Select minimally processed, pure options. Soybean meal is high in protein and adds nitrogen after fermentation.  

2. Quality Checkpoints

Nutrients: Look for raw materials with at least 45% organic matter content. Balanced ratios of N, P, and K are critical for effective fertilizer.  

Safety: Closely monitor heavy metals (lead, mercury, cadmium) and pesticide residues. Excess levels can pollute soil and harm crop quality.  

3. Supply Reliability  

A stable supply of raw materials is essential for organic fertilizer production lines. Selecting raw materials with a long-term and stable supply source can ensure the continuous operation of the production line and avoid production interruptions caused by raw material shortages.

In short, in the organic fertilizer production line, the selection of high-quality organic fertilizer raw materials requires comprehensive consideration from many aspects, so that efficient and environmentally friendly organic fertilizer products can be produced.
