How to compost organic waste (such as manure from livestock, poultry and agricultural waste)

Біріншіден, you should prepare raw materials and adjust to favorable fermentation conditions. If you want to compost animal manure, you can add some sawdust and straw powder to adjust water content and C/N ratio. The most suitable moisture for composting is 50% дейін 60%, and the suitable C/N ratio is 25:1. Then, you can mix them evenly.

Екіншіден, you start to make compost piles. You can pile organic waste in long rows or windrows, or you can put them in a fermentation groove. The size of compost pile should be proper, because too larger or small size will influence the final quality of compost.

Ақырында, you need to regularly turn the compost pile. Компосттау кезінде, microorganisms will digest organic matter, consume oxygen and waster, and produce heat. Сондықтан, you should turn the compost pile, so as to provide enough air for organic matter decomposition.

Ескерту: For the fermentation, it will cost about 20 күндер. In the first week, you need to turn compost pile 2-3 times or 3-4 times per day. Once the raw materials temperature reach on 50-60 degrees Celsius, you need to turn the raw materials to help them heat dissipation. After one week, you can turn the raw materials one time for 1-2 күндер. As long as the temperature does not increase anymore, and the raw materials can be powder by hand hold, then the fermentation is done.

Do you need to add extra materials during composting?

Yes, you need to add some fermentation strains, so as to increase microorganism content during composting.

Why should we compost organic waste before application?

Let us take animal manure as an example. Бір жағынан қарағанда, fresh animal manure contains many pathogens, weed seed and worm eggs, which may pollute plants and soil. Басқа жақтан, the fresh manure will ferment in the soil after direct application, which may burn plant roots. Сондықтан, composting is necessary for using animal manure as fertilizer.

How much work area is needed for fermentation?

It depends on the specific conditions. We can provide you a formula for calculation. Work area= hourly output* work time* fermentation period/ density of fermentation material/ height of compost pile.

What’s moisture of materials before and after fermentation?

Before fermentation, the moisture is 50% дейін 60%. And after fermentation, the moisture is 25% дейін 30%.

How long does it take to compost organic waste?

With the help of compost turner, it will be finished in 20 дейін 30 күндер.

Will organic waste become powder after fermentation?

Yes. But compost caking may exist.
