Kompostiranje je prednostna izbira za večino ljudi pri delu z živalskim gnojem, kot sta živinski in perutninski gnoj. Ker bo gnoj postal kompost, ki vsebuje potrebna rastlinska hranila in se lahko uporablja kot organsko gnojilo. Na kratko, kompostiranje je naraven proces, kjer mikroorganizmi pod nadzorovanimi pogoji razgradijo organske snovi v gnoju v humus. Dobro je tako za zemljo kot za rastline. Zato, lahko ga uporabite kot osnovno gnojilo na svoji zemlji, lahko pa proizvedete tržno organsko gnojilo v vrečah. Za sistem kompostiranja gnoja, o tem lahko veste iz naslednjih vidikov, vključno s postopkom kompostiranja, metode kompostiranja, stroji, ki se uporabljajo pri kompostiranju, pogoji kompostiranja, in globoko predelavo po kompostiranju.
Kakšen je celoten postopek kompostiranja za pretvorbo gnoja v gnojilo?
Če želite kompostirati živalski gnoj (kot npr kompostiranje prašičjega gnoja, kompostiranje kravjih iztrebkov in kompostiranje konjskega gnoja), morate opraviti naslednja dela, vključno z zbiranjem gnoja (in posteljnino) iz hleva, naredite kompostni kup in ga redno obračajte, dokler se fermentacija ne konča. Podroben postopek je kot spodaj:
Zbiranje gnoja in dodajanje pomožnih materialov
Prvo delo pri kompostiranju živalskega gnoja je priprava surovin. Ko pobirate gnoj iz hleva, lahko zbirate tudi odsluženo posteljnino (ki se lahko uporabljajo kot sredstva za povečanje prostornine in prilagodijo razmerje C/N). Poleg tega, gnoju lahko dodate nekaj sesekljane slame ali žagovine. In razmerje med gnojem in dodatkom je običajno takšno 3:1. Za obsežno ali komercialno kompostiranje gnoja, dodati morate tudi dodatne seve za fermentacijo, tako da zagotovimo zadostno vsebnost mikroorganizmov med kompostiranjem. medtem, več pozornosti morate posvetiti vlažnosti gnoja, kar bo posredno vplivalo na vsebnost kisika v kompostnem kupu. Če je vsebnost vode v zbranem gnoju previsoka, lahko posvojiš Separator gnoja SEEC za odstranitev odvečne tekočine. Ker je primerna vlaga za kompostiranje 50% do 60%.
Izdelava kompostnega kupa
Na voljo sta kopičenje surovin na tleh v dolgih vrstah in polaganje v fermentacijske utore.. Izdelava komposta v dolgih gredah zahteva več prostora. Višina okovja se giblje od 0.6 m do 1.8 m, širina pa je od 2 m do 3 m. Če je kompostni kup premajhen, gnoj se bo težko segrel v kratkem času, kar bo vplivalo na proces kompostiranja in kakovost komposta. Na drugi strani, lahko zgradite nekaj vzporednih fermentacijskih utorov za odlaganje organskih odpadkov. Globina materiala v utorih je običajno 0.8 m, 1.0 m,1.2 m oz 1.5 m. Ker je obračalnik komposta pomemben pri procesu kompostiranja, ki vam lahko pomaga prilagoditi pogoje fermentacije. Velikost kompostnega kupa lahko določite glede na model obračalnika komposta, ki ga izberete.
Redno obračanje kompostnega kupa
Po zlaganju materialov skupaj, se začne kompostiranje. V tem procesu, mikroorganizmi proizvajajo količino toplote. Po eni strani, visoka temperatura pomeni uspešen začetek fermentacije. Na drugi strani, previsoka temperatura bo zavirala delovanje mikroorganizmov. Zato, potrebno je redno obračanje kompostnega kupa. V prvem tednu, aktivnost mikroorganizmov je močna, zato morate surovine obračati 2-3 čas vsak dan. V naslednjih tednih, lahko zmanjšate na enkrat na dva dni. The turning of compost pile not only can mix materials evenly and make fermentation more complete, but also add more oxygen for microorganism activity. Na splošno, fermentation will finish in 20 do 30 days with the help of composting equipment.
What kind of manure composting system can you adopt?
According to our experience, efficient ways to compost animal manure include making compost pile and vermicompost. The former method includes windrow composting and composting animal manure in fermentation grooves. And the latter needs the involvement of earth worms.
Kompostiranje v oknu & composting animal manure in fermentation grooves
You can pile raw materials in long rows, which is easy to arrange. You need to prepare enough space according to the volume of organic waste. In order to guarantee the quality of compost, you had better make a shelter if you make compost pile in the open air. Kaj je več, the ground shall be concrete, which can provide good working condition for compost turner and effectively prevent soil from pollution. In terms of the latter, you need build fermentation groove, which consists of three walls. The fermentation grooves usually are made up of bricks and cement. Compared with windrow composting, fermentation grooves can save space.
Vermicomposting
You can stack raw materials together and mix them evenly. Potem, you should put earth worms in it. By the digestion of earth worms, organic matters in manure will become valuable vermicompost. To ensure the smooth progress, you should place compost pile with earth worms under shelter, and you can also cover it with straws, so as to keep the moisture of compost piles.
Composting manure quickly with SEEC manure composting equipment —large scale/small scale/windrow compost turner
Composting equipment is an important tool in manure composting system. Kot gnoj za proizvajalca opreme za gnojenje, SEEC produces various kinds of compost turner with different working principles and models. All of them can shorten composting period and improve quality of compost. Now, let us know more about them. And you can choose suitable one to make your own manure composting system.

Kaj je več, you can equip it with automatic discharge device, so as to improve working efficiency and provide convenience for subsequent operations.
Small-scale compost turner for farm manure management and small-scale organic fertilizer factory
For farm manure composting and composting work in a small-scale fertilizer factory, we recommend groove type compost turner and forklift type compost turner.
- Groove type compost turner: It works on the fermentation grooves. Its main parts include control panel, groove changing device (it can help compost turner move from one groove to other grooves) and electric cable winding wheel. Poleg tega, you can equip it with water spray system, which can add water to compost pile during turning. Nadalje, its turning depth usually is 0.8m, 1.0m,1.2m and 1.5m. Its turning teeth adopt 16 Mn, which can turn raw materials evenly and crush caking.
- Forklift type compost turner: Its functions mainly focus on its bucket, which can finish crushing and mixing raw materials. The discharge port at the bottom of bucket adopts hydraulic control, which is easy to operate. You can use it in workshop or in the open air.
Windrow compost turner for composting manure quickly
Windrow composting is one of common manure composting systems. You just need to pile up organic waste in long rows. medtem, space with a shelter will be better. Potem, you can adopt windrow compost turner to regularly stir the compost pile, so that you can get quality compost in a short time. Poleg tega, all windrow compost turner use diesel oil as fuel, which can provide more power to the whole machine.
- Crawler type compost turner: It adopts rubber track chassis, which can provide stable support during working. Its humanized design is the driver’s cab, which can separate worker from heat and odor generated from compost pile.
- Self-propelled compost turner: It is also called moving type compost turner. Its four wheels greatly increase its flexibility in operation. Its turning teeth can well turn and crush organic waste, so as to provide favorable environment for fermentation.
Moisture, temperature and oxygen—three essential factors for a successful manure composting system
During aerobic composting, oxygen-consuming bacteria and fungi will consume water, oxygen, nitrogen (N) and carbon (C), and produce nutrient-rich humus. Given this, you should strictly control the moisture and oxygen of the compost pile. medtem, amount of heat will be generated during composting because of microorganism activity. Vendar, when the temperature is above 60 stopinja Celzija, the microorganism will be affected and even inhibited. torej, you should pay more attention to the three factors.
How to maintain suitable moisture?
The suitable moisture for composting is 50% do 60%. If you adopt fresh manure with higher moisture (such as manure cleaned by rinsing) to compost, you can adopt solid liquid separator to remove extra liquid. For fresh manure collected directly, you can adjust its moisture by adding some straw, žagovina and other organic wastes with stronger water absorbency. Besides adjusting moisture, as carbon-rich materials, straw and sawdust can also adjust C/N ratio of compost pile. Conversely, if the manure is dry, you need to add some water. One of easy methods for testing moisture is: Catch a handful of manure, if the manure can stick together in a ball without water droplets, that means moisture is suitable.
Adjusting temperature and oxygen content in manure composting system
The adjustment of temperature and oxygen occur during composting. During fermentation, microorganism will consume oxygen to convert organic matters into compost. medtem, this process will produce amount of heat. If the temperature in the compost pile is too high, composting process will be affected due to the decrease of microorganism activity. The efficient method for dealing with this problem is to regularly turn the compost pile. With the turning of raw materials, the involvement of air will increase oxygen content and lower temperature. Kaj je več, this operation can mix raw materials evenly, so as to guarantee thorough fermentation.
Sometimes, other special conditions will appear, for example, there is no definite temperature rise for a long time. In such case, you should exam the moisture, C/N ratio and microorganism content of the compost pile. Too drier organic waste, lower C/N ratio and weaker microorganism activities will inhibit the fermentation.
Systems for you to make commercial organic fertilizer from composted animal manure
Po kompostiranju, animal waste becomes nutrient-rich compost. After several days’ stabilization, you can apply it to plants and soil. In addition to personal use, you also can make commercial fertilizer from composted manure. There are two methods to make commercial organic waste. One is powdery organic fertilizer production and the other is granular fertilizer production. They have some differences on production process and manure processing machinery.
Powdery organic fertilizer production: Composting process (obračalnik komposta) —postopek drobljenja (vertical crusher) —postopek presejanja (rotary screen machine) —postopek pakiranja (powdery fertilizer bagging machine)
Granular fertilizer production: Composting process (composting equipment) —postopek drobljenja (drobilec komposta)—postopek presejanja (zaslon za kompost)—granulating process (organic fertilizer granulator)—postopek presejanja (rotary screen machine for selecting out oversized and undersized pellets)—drying and cooling process (rotary drum drying and cooling machine)—packaging process (fertilizer pellets packing machine).
