Sheep Manure Cannot be Directly Used as Fertilizer

First, sheep feces contain coliforms such as coliforms and nematodes. If used directly, it will lead to the spread of pests and diseases, the incidence of crops, and the phenomenon of burning roots and so on. Therefore, sheep manure needs to be fermented to be safer.


Not only sheep dung, but also all kinds of livestock and poultry including human dung contain a large number of germs, eggs and parasites. Unfermented manure can not be directly applied to crops!


Second: the sheep manure fermentation process will dissipate most of the heat. If it is not fermented directly, it will cause the plants to burn roots and burn seedlings.


Third, the nitrogen fertilizer in the sheep manure begins to exist in the form of protein. The plant cannot directly use the protein, and only after the fermentation, the protein is decomposed into ammonia to be used by the plant.

Pig manure contains 15% organic matter, nitrogen (N) 0.5%, phosphorus (P2O5) 0.5-0.6%, and potassium (K2O) 0.35-0.45%.


The texture is fine and the composition is complex, containing protein, fat, organic acid, cellulose, hemicellulose and inorganic salts.


It contains more nitrogen and has a smaller carbon to nitrogen ratio (14:1). It is generally prone to decomposition by microorganisms and releases nutrients that can be absorbed and utilized by crops.


Cow dung contains 14.5% organic matter, nitrogen (N) 0.30-0.45%, phosphorus (P2O5) 0.15-0.25%, and potassium (K2O) 0.10-0.15%.


Its organic matter and nutrient content are the lowest among all kinds of livestock, the texture is fine, the water content is more, the decomposition is slow, the calorific value is low, and it is a late-acting fertilizer.


Horse manure contains 21% organic matter, nitrogen (N) 0.4-0.5%, phosphorus (P2O5) 0.2-0.3%, and potassium (K2O) 0.35-0.45%. The content of cellulose and hemicellulose is high in the composition.
