Compared with other livestock and poultry manure organic fertilizers, cow dung organic fertilizer cannot simply be said to have more comprehensive nutrients.

1. Nutrient characteristics:

① The organic matter content in cow dung is relatively high, generally around 14.5%.

② The nitrogen, phosphorus and potassium content are relatively low, of which the nitrogen content is about 0.30%-0.45%, the phosphorus content is about 0.15%-0.25%, and the potassium content is about 0.10%-0.15%.

③ It contains relatively rich cellulose and hemicellulose, etc., which can improve the soil structure.

2. Other advantages:

① The texture of cow dung is relatively fine, the water content is high, the temperature rises relatively slowly during the fermentation process, but the temperature retention time is longer, which is conducive to the stable progress of the composting process.

② The source of cow dung is relatively wide and the cost is relatively low.

In summary, cow dung organic fertilizer has its own characteristics and advantages. Different livestock and poultry manure organic fertilizers differ in nutrient content, composting characteristics, etc., and can be reasonably selected and used in combination according to actual needs.
