Chicken manure, cow manure, pig manure, sheep manure, which is the most suitable fertilizer?

Manure is rich in organic matter and various nutrients needed by crops, which have a good effect on increasing crop yield and improving soil fertility. It has been widely used in agricultural production.But in recent years muck fertilizer is unreasonable apply phenomenon also apparent increase in number, muck fertilizer was used wrong ground, do not have good result not only, still can have the opposite effect, so what muck fertilizer suits what kind of soil?

The main composition of all kinds of animal manure

pig

Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus and 0.35-0.45% potassium.Pig manure is fine in texture and complex in composition. It contains proteins, fats, organic acids, cellulose, hemicellulose and inorganic salts.Due to the high nitrogen content, the proportion of carbon and nitrogen is relatively small, about 14:1, which is easily decomposed by microorganisms and releases nutrients that can be absorbed and utilized by crops.

Pig manure has the highest humus content, the largest amount of Yang li substitution and the strongest fertility retention. However, it contains more water and less cellulose decomposing bacteria. A small amount of horse manure is mixed to inoculate cellulose decomposing bacteria, which can greatly increase the fertility effect.

Cow dung

Cow manure contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus and 0.10-0.15% potassium.Organic matter and nutrient content in various livestock is low, fine texture, more water, slow decomposition, low calorific value, is a late-acting fertilizer.

Cow manure is a cold fertilizer because of its high water content, poor air permeability and difficult decomposition of organic matter.

Horse manure

Horse manure contains 21% organic matter, 0.4-0.5% nitrogen, 0.2-0.3% phosphorus and 0.35-0.45% potassium.Horse manure contains more cellulose, hemicellulose, lignin, protein, fat, organic acids and a variety of inorganic salts.

The water in horse manure is easy to evaporate and contains more fiber decomposing bacteria. It is a thermal fertilizer, and the application of horse manure can improve the properties of clay.

dung

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, which is fine and rich in fat.

Sheep manure fever is between horse manure and cow manure, also belongs to the thermal fertilizer, also known as the thermal fertilizer, applied on sandy soil and clay soil, the effect is good.

Poultry dung

Bird manure contains 25.5 % organic matter, 1.63% nitrogen, 1.54 % phosphorus, 0.85% potassium, 11% carbohydrate and 7% fiber.

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

The advantage of muck fertilizer and hidden trouble

Advantages of manure

The nutrient place that muck fertilizer contains is more comprehensive, fertilizer effect is stable and lasting.It not only contains a variety of large and medium micronutrients, but also contains some substances that can stimulate root system growth and various beneficial soil microorganisms.

Manure is rich in humic acid, which can improve soil structure, promote the formation of soil aggregate structure, make soil soft, improve soil moisture and air conditions, and facilitate root growth.Increase soil fertility and water retention;Raise ground temperature, promote the activity of beneficial microorganism in soil and breed.

Muck fertilizer has the cent of hot sex, lukewarm sex and cool sex, have the effect that adjusts soil temperature.

The hidden danger of manure

Uncooked manure, especially poultry manure, has heavy salt content, which is easy to salinize the soil and increase the salt concentration of the soil. If it is serious, seeds will not germinate, seedlings and roots will be burned.It also produces harmful gases and poisons plants.

There are many bacteria, insect eggs, weed seeds and so on in the livestock excrement and urine, do not pass the high temperature ferment, very easy to bring the adverse effect to the plant, but also easy to cause the disease and insect pest.

Because source problem, partial muck fertilizer may microelement content exceeds mark, even contain heavy metal, antibiotic to wait, can poison a plant, affect produce safety.

Because of many impurities, the purity of manure varies greatly, and its content is extremely unstable, the nutrient content and effect cannot be guaranteed when applied alone.

How should manure be used after all?

Manure must be thoroughly decomposed when used

Manure rotten quickly after decomposition, which is beneficial to the plant absorption, at the same time in the 60-70 ℃ high temperature anaerobic environment, bad eggs, weed seeds, most of the die.

At present, there are three commonly used methods to decompose manure:

One is the combination of high temperature stuffy shed for manure maturation.Summer shed leisure period is long, can be combined with high temperature stuffy shed for manure maturation, maturation fermentation process is also a process of soil improvement.In the process of fermentation and maturation, soil microorganisms are very active, which can promote the formation of soil aggregate structure.

Second, the heap outside the shed stuffy.There is enough time for the natural compost fermentation, and a short time can be used in the compost compost maturation agent.

Third, the use of bacteria agent rapid fermentation.ETS microflora is commonly used to shorten the fermentation and maturation time.
