Solution to Process Cow Dung Into Organic Fertilizer

Without proper disposal, cow dung would cause a series of issues to environment and even become a direct threat to human and livestock health. It generates lots of greenhouse gas - methane, not only seriously restricting the sustainable development of cattle farming industry, but also having adverse impact on climate change. The untreated manure would heavily pollute surface water, underground water, surrounding air and soil, bringing big hidden trouble and pressure for environment protection. Therefore, proper disposal for cow dung is extremely urgent.

Currently, the most common and valuable processing method is to turn cow dung/manure into sellable organic fertilizer. Cow dung is a derived product from wastes produced by cattle, providing high levels of organic materials and rich in nutrients, including about nitrogen, phosphorous and potassium as well as many other essential nutrients. According to the data, daily cow dung contain 12.9% DM and excreting a total of 0.15kg N, 0.04kg P and 0.08kg K. Moreover, cow manure also contains high levels of ammonia that can almost kill the growth of the pathogens. Once raw cow dung composted by professional compost turner, it can provide lots of benefits to the garden and organic farm, which makes cow manure very popular and useful raw material of organic fertilizer production.

As one of the most important source to prepare effective bio/organic fertilizer, the processing method of cow dung organic fertilizer is first to collect the cattle residue. Heavy cow manure should be mixed with organic substances like vegetable waste, garden debris, dead leaves, sawdust, wood ash, hay and straw etc. The mixed cow dung is then subjected to better composting and fermentation via compost turner machine. After fully composting, cow dung would be transferred into crusher for materials grinding, in order to make sure smooth granulating process. Remember to choose a suitable organic fertilizer granulator according to the scale of cow manure composting and production. Usually, for easy packaging and storage, a rotary dryer would be used to evenly dry the granules and ultimately create a uniform and quality final product. Finally, we also provide an automated packaging machine so as to fulfill high-efficiency, automatic and convenient packaging and bagging solution for finished organic fertilizers. Here, we will discuss the two major procedures of cow dung disposal - aerobic composting process and granulation process in detail.

Benefits of Cow Manure Composting Organic Fertilizer

※ With satisfactory NPK content, cow dung organic fertilizer after composting and granulation can eliminate harmful ammonia gas and pathogens, add large amount of organic matter to the soil and supply plant nutrients.

※ It is an important input for maintaining and enhancing soil fertility, which can grow up healthy vigorous plant, and improve agricultural productivity and crop output, which is a need of a developing nation, such as Vietnam, Thailand and Philippines, etc. So the application of cow dung organic fertilizer in proper and sustainable way can enhance not only productivity of crops yield but also reduce disease incidence caused by a wide range of plant pathogens including bacteria, fungi, and nematode species.

※ What's more, making cow dung into organic fertilizer is conducive to environment protection by greatly reducing foul smell, air pollution and mosquitoes and flies harm caused by cow manure.
