Mafetireza emumba anogadzirwa nekuvirisa mafetireza akasiyana emumba.Chinonyanya kushandiswa mupfudze wehuku, mupfudze wemombe, nemupfudze wenguruve.Pakati pavo, mupfudze wehuku unonyanya kukodzera fetireza, asi mhedzisiro yemupfudze wemombe ishoma.Fermented organic fetereza inofanirwa kutarisisa kune kabhoni-nitrogen ratio, mwando, oxygen yemukati, tembiricha, uye pH.Tichavarondedzera zvakadzama pazasi:
1. Mupfudze wehuku ifotereza ine organic, uye fetiraiza inoshanda yemafetireza matatu yakakwira, asi nitrogen mumupfudze wehuku haigoni kubatwa zvakananga nezvirimwa.Kana ikaiswa pamunda chaipo, inokonzeresa kufa kwechirimwa.Izvi zvinodaro nekuti mupfudze wehuku une uric acid, iyo inotadzisa kukura kwemidzi yezvirimwa.Mupfudze wehuku, kune rumwe rutivi, wakanyanya muorganic uye wakaviriswa mumunda unopisa uye unokuvadza midzi yezvirimwa.Naizvozvo, mupfudze wehuku unofanira kunyatsoviriswa nekuwora usati washandiswa sefotereza.Zvisinei, manyowa ehuku ari nyore kuwora uye tembiricha iri kuparara yakakwira zvakati.Ndeyefetereza inodziya.Uchishandisa manyowa ehuku sehupfu, inovirisa nekuora nekukasika, uye inogona kuitwa fetireza ine kudya kwakawanda.Iyo yakanaka kwazvo mbishi zvinhu zvekugadzira manyowa.
2. Mupfudze wenguruve ndiwo mupfudze wakapfava pakati pehutatu.Mupfudze wenguruve une yakakwira nitrogen asi zvakare ine mvura yakawanda, pakati peiyo organic matter iri pakati nepakati uye iri nyore kuora.Inoputsika nekukasira panguva yekuibva.Nguruve yenguruve ine humus yakawanda, iyo isingangogone kuchengetedza nitrogen, phosphorus, potassium fertilizer muvhu, asiwo inowedzera kuvandudza: chimiro chevhu chinobatsira kuchengetedza mvura uye fetiraiza muvhu, asi manyowa enguruve anewo akawanda. mabhakitiriya uye zvipenyu zvinokuvadza zvisati zvashandiswa zvinoda kuputswa.
3. Ndove yemombe ndiyo ine fetereza yakashata pakati pevatatu, asi ndiyo yakapfava.Iyo organic matter yakanyanya kuoma kuora, inoora zvishoma nezvishoma, uye tembiricha yekuvirisa yakaderera.Nekuti mombe dzinodya chikafu, ndove yemombe ine cellulose.Kunyanya, zviri mukati me nitrogen, phosphorus, uye potassium zvakaderera, uye hazvizokonzeri kuwandisa fetiraiza mhedzisiro uye kukuvadza kune zvirimwa kana ikaiswa kumunda, asi mombe dzinenge dziine mhodzi zhinji dzeuswa panguva yekufura.Kana dzisina kuora, mhodzi dzeuswa dzinenge dziri mumunda.Midzi uye yakamera.
4. Mupfudze wemakwai wakanaka mukugadzirwa uye kuderera mumvura, uye chimiro chayo che nitrogen chinonyanya urea nitrogen, iyo iri nyore kuparara uye kushandiswa.
5. Mushonga webhiza une huwandu hwehuwandu hwehuwandu hwehupenyu, uye hunewo huwandu hwefiber-decomposing bacteria, iyo inogona kuunza kutonhora kwakanyanya panguva yekugadzira manyowa.
