What are the methods for handling cow manure on cattle farms?

In recent years, the cattle industry has developed rapidly, and with the continuous growth of large-scale cattle farms, the problem of cattle farming pollution has become increasingly serious. The most prominent issue is how to handle cow manure. Much cow manure is left untreated on open-air vacant lots, causing air pollution and breeding large numbers of mosquitoes and flies, which affects the surrounding living environment. Let's take a look below at how cow manure is handled on cattle farms!

Building biogas digesters

Building biogas digesters is the best method for handling cow manure on small cattle farms. Using cow manure and cattle farm pollutants as raw materials, with an investment of just a few thousand yuan, it not only solves the fuel source for the local people but also allows the cow manure to be fully decomposed. The biogas residue and liquid are excellent organic fertilizers that can improve the intrinsic quality of fruits and vegetables and reduce costs. However, small biogas digesters built now do not have power generation capability, so they are generally suitable for small cattle farms.

Cow manure organic fertilizer

Dried cow manure contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract, and 15-30% crude fiber. It has high nutrient content and can become a high-quality organic fertilizer product after fermentation. It can loosen the soil, improve soil compaction, chelate trace elements in the soil, and enhance soil fertility. At the same time, using cow manure as a raw material to produce organic fertilizer has low costs, relatively stable quality, and great market sales potential.

Using cow manure to raise earthworms

Earthworm farming is now a new industry with low farming costs and good profits. Cow manure can be used for farming, and cattle farms have better conditions for developing earthworm farming than others, using local materials. Cow manure does not need to be purchased, feeding is simple, and it increases extra income for the cattle farm. Earthworm powder is an excellent feed additive, with a higher protein content than fish meal. Moreover, various special fertilizers produced with earthworm castings as the main raw material not only have high fertilizer efficiency but can also inhibit the spread of crop diseases and pests, while also raising soil temperature and retaining water and fertilizer.

Growing mushrooms with cow manure

Cow manure is the best raw material for growing mushrooms. In recent years, with the development of the edible fungus industry, the demand for cow manure as a material has also grown. The cow manure produced by one cow in a year can grow one mu of mushrooms, and the output value per mu of mushroom cultivation can exceed 10,000 yuan. The most popular approach is growing button mushrooms (Agaricus bisporus) with cow manure. The market price of button mushrooms remains high, mainly because the cultivation area is small, and the main raw material for growing button mushrooms is cow manure.

Producing seedling-raising soil

Seedling-raising soil refers to specialized soil for raising seedlings, prepared by mixing field soil, decomposed organic fertilizer, loose materials, and chemical fertilizers in certain proportions. It requires complete nutrients, moderate alkalinity, looseness and permeability, and strong water retention capacity. As one of the best fertilizers, cow manure can be used with crop straw to produce cultivation substrates and bio-organic fertilizers, which reduces environmental pollution and meets market demand.
