Nutrients in Different Poultry Manure

Nutrients in different poultry manure

●Pig manure

Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5 to 0.6% phosphorus, and 0.35 to 0.45% potassium. Pig manure has a fine texture and complex composition, containing protein, fat, 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.

●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.

Due to the high water content and poor aeration in cow manure, the organic matter part is more difficult to decompose and is a cold fertilizer, dry the fresh class and then add horse manure to the mixed pile to get 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, fat, 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 to 27% organic matter, 0.7 to 0.8% nitrogen, 0.45 to 0.6% phosphorus and 0.4 to 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 belongs to the hot fertilizer, also known as warm fertilizer, applied on sandy soil and clayey soil, the effect is good.

●Chicken manure

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

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, and fresh poultry manure is easy to attract underground pests.
