Everywhere there are animals, you can be sure there will also be animal manure. As cattle farming has become more industrial, specialized and intensified, the environmental pollution caused by cow dung has made the need to find ways to utilize the waste essential. Hence, the invention of commercial cow dung fertilizer machines.
An average unit of beef cattle produces over 10 tons of animal waste each year, while an average unit of dairy cows produces over 15 tons of animal waste each year. A single dairy farm, with just 2500 cows produces the same amount of waste as a city with a population of 411,000. Manure management is a big problem for many farms around the world. In some areas, cow dung pollution causes more issues than industrial pollution.
The good news is that cow dung is an excellent source of organic fertilizer. It is rich in key nutrients and high in organic matter. Cow dung contains around 2% phosphorus, 3% nitrogen and 1% potassium. In addition to organic matter and key plant nutrients, cow dung also contains various microorganisms and enzymes. With cow dung fertilizer machines, cow waste can be converted into a high-grade organic fertilizer which can improve many characteristics of soil, including fertility, microbial environment, and drainage.
While cow manure is a great fertilizer, fresh cow dung is high in ammonia, which can burn plants and give off an unpleasant odor. Furthermore, it often contains excess salt. Composting the cow dung is a good way to create a more effective fertilizer. A cow dung fertilizer machine is used to fully decompose fresh cow manure quickly.
If fresh cow dung is applied directly to the soil before it is fully decomposed, it can cause soil temperature to sky-rocket damaging crop root systems. What’s more, it can produce harmful toxins and pathogens. These toxins can get into water supplies and cause massive environmental pollution problems.
Cow manure needs to go through composting and further processing to turn it into a safe organic fertilizer in the form of granules or powder. High-grade organic cow manure fertilizer production requires advanced technology. The two main steps involved are composting and cow dung granulation.
During the composting stage, the cattle manure must be fully fermented. There is a range of methods that can be used to check whether the manure is fully fermented. A primitive approach is just to look at the color.
The investment in top-grade fertilizer machinery is essential for the effective production of NPK fertilizer from cow dung. A typically compound fertilizer production line will consist of a range of equipment including, self-propelled compost turner, cow dung fertilizer pelletizers, screening machines, drying equipment, packing machines and more.
There are lots of affordable organic fertilizer granulating machines in the marketplace. The main reason why NPK organic fertilizer manufacturers seek to turn powder into pellets is that pellets are more convenient for storage and transportation. What’s more, pellets take longer to deteriorate in quality than powder, so granulated organic fertilizers have a longer shelflife.
