Chicken Manure, Pig Manure, Sheep Manure, Cow Manure, Which is Better as Fertilizer

Manure is rich in organic matter and various nutrients needed by crops, and it has a good effect on increasing crop yield and improving soil fertility, so it has been widely used in agricultural production. In ancient times, it is said that "more manure is more fertilizer, more fertilizer is more fertile, and fertile field is more grain". In recent years, with the increase of unreasonable application of manure, various problems have arisen.

Main components of various types of livestock manure.
The main components of livestock manure are cellulose, hemicellulose, lignin, protein and its decomposition components, fat, organic acids, enzymes and various inorganic salts.

Pig manure
Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5 to 0.6% phosphorus and 0.35 to 0.45% potassium. The texture of pig manure is fine and the composition is complex, containing proteins, fatty species, organic acids, cellulose, hemicellulose and inorganic salts. Because it contains more nitrogen, the carbon to nitrogen ratio is small, about 14:1, and it is generally easy to be decomposed by microorganisms, releasing nutrients that can be absorbed and used by crops.

Pig manure contains the highest amount of humic substances, the largest amount of Yang free substitution, and the strongest fertilizing power, but it contains more water and less cellulolytic bacteria, so mixing a small amount of horse manure and applying it to inoculate cellulolytic bacteria can greatly increase the fertilizing effect.

Cow manure
Cow manure contains 14.5% organic matter, 0.30~0.45% nitrogen, 0.15~0.25% phosphorus and 0.10~0.15% potassium. The organic matter and nutrient content are low among various livestock, with fine texture, more water, slow decomposition, low heat generation, and is a late-effect fertilizer.
The organic matter part is difficult to decompose due to the high water content and poor aeration in cow manure, which is a cold fertilizer, and the fresh class is dried and mixed with horse manure to obtain loose and high quality organic fertilizer.

Horse manure
Horse manure contains 21% organic matter, 0.4 to 0.5% nitrogen, 0.2 to 0.3% phosphorus and 0.35 to 0.45% potassium. The composition of horse manure contains more cellulose and hemicellulose, in addition, it also contains lignin, protein, fatty species, organic acid and many kinds of inorganic salts.

The water in horse manure is easy to evaporate, and it also contains more fibrous decomposing bacteria, so it is a thermal fertilizer, and the application of horse manure can improve the nature of clay soil.

Sheep manure
Sheep manure contains 24~27% organic matter, 0.7~0.8% nitrogen, 0.45~0.6% phosphorus and 0.4~0.5% potassium. Sheep manure contains more organic matter than other livestock manure, the manure is fine, and the fertilizer is thick.
Sheep manure heat between horse manure and cow manure, also belong to the hot fertilizer, also known as warm fertilizer, in the sandy soil and clay soil application, the effect is good.

Poultry manure
Poultry manure contains 25.5 % organic matter, 1.63 % nitrogen, 1.54 % phosphorus, 0.85 % potassium, 11 % carbohydrates, 7 % fiber, and high water content in fresh poultry manure.

The nitrogen in poultry manure (chicken manure, duck manure, goose manure, pigeon manure, etc.) is mainly in the form of uric acid, which cannot be directly absorbed and used by crops, and is harmful to the growth of crop roots.
