Pig Manure Management

Pig manure management is a serious problem for pig farm or some manure composting factories. In view of excellent nutrient content in pig manure, composting is the most suitable way to deal with pig manure. In addition to composting, pig manure compost fertilizer production is also available for both pig farm and larger organic fertilizer factory.

Why pig manure management is important for you?

Pig manure contains much water, which is usually stored in the slurry pit. Because of unpleasant smell and its attraction to flies, the long-time stacking of pig manure will cause pollution for surrounding environment and residents. On the other hand, pig manure contains much nutrient elements, such as nitrogen, phosphorous and potassium. Therefore, it can be used as good fertilizer for soil and plants. You can convert it to organic fertilizer by composting and produce commercial pig manure fertilizer. In this way, you can dispose pig waste efficiently and decrease your own fertilizer cost or make more profits.

In terms of pig farm waste management, what solutions can Tongda provide you?

Pig manure management on the pig farm can start from composting or a small-scale compost fertilizer production line. If you just want to convert pig manure into compost for personal use, composting is enough. The small-scale compost fertilizer production is suitable for commercial pig manure compost production. And you can sell them to other people or in organic fertilizer markets. The detailed steps include:

Windrow composting process

Windrow composting is an easy and fast way to compost pig manure. You just need to collect pig manure and pile it in windrows with auxiliary materials (sawdust and straw powder, etc.).

Because pig manure belongs to nitrogen-rich material. You need to add some carbon-rich materials (pin shaving, hay and straw from bedding) to maintain C/N ratio (25:1/30:1). Then you need to mix them evenly, so as to guarantee compost quality. Here, you can adopt windrow compost turner, whose stirring apparatus can mix these materials evenly, and turn the compost pile regularly to create favorable fermentation conditions. In the early stage of composting, you may need turn the compost 1 or 3 times per day. Two weeks later, you can turn it 1 time every two days. The turning of compost pile will redistribute moisture, move less degraded materials on the surface to inside of pile and release extra heat.

Crushing process

The purpose of this step is to produce uniform and fine powder. When the fermentation finishes, the water content of pig manure compost is 25% to 30%. The size of compost may be a little big, and caking may exist because of long-time stack. Therefore, you need to crush pig manure compost after fermentation, which can also provide convenience for sieving process. Both Tongda new type vertical crusher and semi-wet material crusher are available.

Screening process

Sieving process is to ensure the purity and uniformity of pig manure compost. Because organic fertilizer screening machine not only can select out impurities, but also separate larger particles. Here, we recommend rotary screen machine, whose screening levels can be customized.

Packing process

In packaging process, you can make bagged pig manure fertilizer. Because bagged organic fertilizer is convenient for use, storage and transportation. Here, you can fill and seal fertilizer bags manually. Or you can adopt automatic packing machine, which can pack pig manure fertilizer in different weights (25kg/50kg).

How can you make special organic fertilizer from pig manure—bio organic fertilizer and vermicompost?

Bio organic fertilizer making for pig manure management

Composted pig manure belongs to quality organic fertilizer, which is nutrient-rich and has no adverse effect to soil. On this basis, you can also make bio organic fertilizer from pig manure. After crushing, you can add functional bacteria by batching machine and blend them evenly. You can finish this operation manually. Or you can adopt Tongda batching machine and fertilizer mixer machine. For large scale bio organic fertilizer production and bio organic fertilizer pellets production, batching machine and fertilizer mixer are essential, which can improve working efficiency and guarantee fertilizer quality. Or you can add functional bacteria by pellets coating machine after granulating.

Vericomposting for pig manure disposal

In addition, you can make vermicompost from pig manure as a method for pig manure management. You can pile up pig manure and straw together, and put earthworms into it. These earth worm will convert pig manure into excellent fertilizer by digestion. As we all know, vermicompost is a kind of valuable organic fertilizer. When pig manure becomes vermicompost, you can make it into compost fertilizer or fertilizer pellets according to above mentioned process. As for the detailed layout, you can refer to this picture (If you have other requirements or problems, you can contact us).

When composting pig manure, you need to pay special attention to three factors

The composting process is the first step in pig manure disposal. Due to its influence on final quality of fertilizer, it is also the most key step. Thus, you must pay more attention to various indicators. Among them, you should focus on moisture, temperature and oxygen content. Meanwhile, this point is also important during dealing with other livestock manures.

Moisture control

Before composting, you should adjust water content of pig manure to 50% to 60%. You can add straw powder or sawdust, which has strong water absorption. Or you can use Tongda solid liquid separator to remove extra water. Because too wet will cause bad ventilation. Too dry will slow heating of compost pile. During composting, you can also sprinkle water according to actual conditions.

Temperature control

You should observe the temperature of compost pile by thermometer. You should turn the compost pile when the temperature reaches 50℃,. Because too higher temperature (above 65℃) will kill good bacteria and microorganism. In the first week, you can turn the compost frequently, 2 to 3 times a day. During the later period of fermentation, you can reduce to 1 time every two days. Because the organic materials nearly run out in the final part. You can adopt compost turner, which can evenly blend outer pig manure and pig manure inside the compost pile.

Oxygen content control

Microorganism digest or decompose organic matters in pig manure while consuming oxygen. When the oxygen is deficient, the microorganism activity will slow. Therefore, you should ensure the ventilation of compost pile. With the help of turning of compost turner, pig manure can fully contact with air. At the same time, the addition of air can also decrease the temperature of compost pile.
