Animal waste, one good material for making organic fertilizer

Animal manure is the byproduct that you can obtain during raising animals. Besides valuable macro- and micro-nutrients, animal manure also contains many plant nutrient and organic matters. However, fresh animal manure usually contains some pathogens, seeds and eggs, which will do harm to soil and plants. Therefore, people always adopt composted animal manure as fertilizer. The Organic matter in animal waste fertilizer can improve soil tilth, increase water-holding capacity, lessen erosion, improve soil aeration and has a beneficial effect on soil microorganisms and plants. On the other hand, the source of organic fertilizer is organic waste, such as agricultural waste, animal waste, food waste and sludge . But when you make compost with any kind of organic waste, the content of animal waste is always 60%. In this way, you can produce organic fertilizer with enough nutrients to soil. So animal waste is an important material for making organic fertilizer.

  • Composting in grooves: Unlike windrow composting, you need to build some grooves for placing animal waste here. The fermentation groove consists of three walls. The depth of placed animal waste should be less than the height of the groove. The features of composting in fermentation groove is large volume and heat preservation.

Tongda animal manure dewatering machine for you to remove extra water in animal waste

As we all know, water content is an important factor during composting. And suitable water content for composting animal waste is 50% to 60%. Too much water will influence the air permeability of compost pile, so as to inhibit microorganism activity and lead to anaerobic fermentation. On the contrary, too less water cannot supply enough moisture to microorganisms, so that the temperature of compost pile is slow to rise. In terms of manure with large water content, we recommend Tongda animal manure dewatering machine to you for separating extra water from animal waste. And this kind of manure includes horse manure, pig manure and cattle manure. Meanwhile, you can add straw or sawdust to adjust water content, which is suitable for animal manure with not much extra water content, such as sheep manure and poultry manure. In addition, Tongda dewatering machine can be used for dealing with other organic waste.
