Njira Yopangira Feteleza wa Organic
Njira yopangira feteleza wa organic nthawi zambiri imakhala ndi izi:
1.Kutoleredwa kwa zopangira: Zida zakuthupi, monga manyowa a nyama, zotsalira za mbewu, ndi zinyalala za chakudya, zimasonkhanitsidwa ndikutumizidwa kumalo opangira feteleza.
2.Pre-treatment: Zida zopangira zimafufuzidwa kuti zichotse zowonongeka zazikulu, monga miyala ndi mapulasitiki, kenako n'kuphwanyidwa kapena kuphwanyidwa mu zidutswa zing'onozing'ono kuti zithandize kupanga kompositi.
3.Composting: Zinthu zakuthupi zimayikidwa mu mulu wa kompositi kapena chotengera ndikuloledwa kuwola kwa milungu ingapo kapena miyezi ingapo.Pochita zimenezi, tizilombo toyambitsa matenda timathyola zinthuzo n’kutulutsa kutentha, zomwe zimathandiza kupha tizilombo toyambitsa matenda ndi udzu.Kompositi ikhoza kuchitidwa pogwiritsa ntchito njira zosiyanasiyana, monga composting aerobic, anaerobic composting, ndi vermicomposting.
4.Kuyatsa: Zinthu zopangidwa ndi kompositi zimafufuzidwanso kuti ziwonjezere michere ndikuchepetsa fungo lililonse lotsala.Izi zikhoza kuchitika pogwiritsa ntchito njira zosiyanasiyana zowotchera, monga kuwira kwa aerobic ndi kuwira kwa anaerobic.
5.Granulation: Zida zofufumitsa zimakhala ndi granulated kapena pelletized kuti zikhale zosavuta kuzigwira ndi kuziyika.Izi zimachitika pogwiritsa ntchito granulator kapena pelletizer makina.
6.Kuwumitsa: Zida za granulated zimawumitsidwa kuti zichotse chinyezi chochulukirapo, zomwe zingayambitse kugwa kapena kuwonongeka.Izi zikhoza kuchitika pogwiritsa ntchito njira zosiyanasiyana zoyanika, monga kuyanika ndi dzuwa, kuyanika mpweya wachilengedwe, kapena kuyanika ndi makina.
7.Screening and grading: The zouma granules ndiye kufufuzidwa kuchotsa oversize kapena undersize particles, ndi graded kuti kuwalekanitsa iwo mu makulidwe osiyanasiyana.
8.Kupaka ndi kusungirako: Chomalizacho chimayikidwa m'matumba kapena zitsulo zina, ndikusungidwa pamalo owuma, ozizira mpaka zitakonzeka kugwiritsidwa ntchito.
Njira yeniyeni yopangira fetereza imatha kusiyanasiyana kutengera mtundu wa zinthu zachilengedwe zomwe zimagwiritsidwa ntchito, michere yomwe ikufunika komanso mtundu wa feteleza womaliza, zida zomwe zilipo komanso zida zomwe zilipo.Ndikofunika kutsata njira zaukhondo ndi chitetezo choyenera panthawi yonse yopangira kuti zitsimikizidwe kuti zabwino ndi chitetezo cha mankhwala omaliza.
