Animal manure contains abundant organic matter and various nutrients required by crops, which have a good effect on increasing crop yield and improving soil fertility. It has been widely used in agricultural production. Today, lets take a look at common types of livestock and poultry manure

Chicken manure contains abundant nutrients, including 18.7% crude protein, 2.5% fat, 13% ash, 11% carbohydrates, 7% fiber, 25.5% organic matter content, and higher nitrogen, phosphorus, and potassium content than pig manure. The application of chicken manure fertilizer not only increases the number of organisms, but also decomposes and converts many organic matter into organisms through the action of microorganisms. This greatly increases the soil adsorption surface and produces many adhesive substances, which bind soil particles together into a stable aggregate structure, improving soil water retention, fertilizer retention, and air permeability, as well as regulating soil temperature.

Chicken manure can improve the soil fertility environment. Applying chicken manure can loosen soil, improve soil aggregate structure, and enhance soil fertility and water retention capacity.

The things to note are:

(1) Before use, it is thoroughly decomposed to inactivate parasites and their eggs, as well as some infectious bacteria present in chicken manure.

(2) Chicken manure has high nutrient content and uric acid content. Do not apply too much fertilizer, otherwise it may cause seedling burning.

Pig manure has a fine texture and contains a lot of organic matter and nutrients such as nitrogen, phosphorus, and potassium. Pig manure decomposes slowly and is suitable as a base fertilizer. Pig manure contains 15% organic matter and a low total nutrient content, with nitrogen of 0.5-0.6%, phosphorus of 0.45-0.5%, and potassium of 0.35-0.45%. Pig manure has a fine texture and complex composition, containing proteins, fats, organic acids, cellulose, hemicellulose, and inorganic salts. Pig manure contains a high amount of nitrogen with a relatively low carbon to nitrogen ratio, and is generally easily decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops.

After fermentation, pig manure is fully decomposed and will not undergo secondary fermentation, eliminating the occurrence of root burning and seedling burning; The fermentation process also decomposes and converts the high molecular weight organic matter contained in pig manure into inorganic salts and minerals that can be directly utilized by crops, and generates bacterial metabolites; The fermentation process is still a biological deodorization process. After fermentation, pig manure fertilizer has no odor and is more convenient to use.

It should be noted that nitrogen is easily decomposed, while proteins, urea, amino acids, uric acid, etc. need to be converted into ammonium salts and nitrates, which are easily decomposed and lost.

Cow manure fertilizer has a slow effect and belongs to the category of "cold fertilizer". Fresh cow manure contains 83.3% moisture, 14.5% organic matter, 0.32% nitrogen, 0.25% phosphorus, 0.16% potassium, 22.56% dry matter, 3.1% crude protein, 0.37% crude fat, 9.84% crude fiber, 5.18% nitrogen free extract, 0.32% calcium, and 0.08% phosphorus. The air dried sample contains 13.74% crude protein, 1.65% crude fat, 43.6% crude fiber, 22.94% nitrogen free extract, 1.40% calcium, and 0.36% phosphorus.

Using cow manure as raw material to produce organic fertilizer has low cost and relatively stable quality. Fermented organic fertilizer has good fertilizer efficiency, is easy to use, does not cause root and seedling burning, and can also enhance soil fertility and improve fertilizer utilization efficiency.

Notes to be noted:

(1) Cow manure should be mixed with straw, grass, peat, or soil as a cushion to absorb urine. Adding thermal manure such as horse manure and sheep manure can promote the maturation of cow manure.

(2) Apply after maturity to ensure nutrient conversion and eliminate bacteria and insect eggs.

(3) Not suitable for mixing with alkaline fertilizers, such as ammonia water, ammonium bicarbonate, etc.

Sheep manure has a nitrogen content of 0.95%, a phosphorus content of 0.35%, and a potassium content of 1.00%. Sheep manure contains high organic nutrient content, decomposes quickly, and is a thermal fertilizer. The same amount of sheep manure applied to the soil has a much higher fertilizer efficiency than other animal manure. Its fertilizer has a quick effect and is easy to apply as topdressing. Sheep manure is a natural green fertilizer, which contains more organic matter than other animal manure. The manure is finer in texture and has a thick fertilizer content, making it a green and environmentally friendly farm manure.
