Akubona bonke abathandi bokulima balwazi ukuthi i-sapropel iyini. Okwamanje, lisetshenziselwa ukukhiqizwa kwezitshalo, ukukhiqiza izilwane kanye nemithi. Ake sibone ukuthi yini into ethakazelisayo njenge-sapropel, lapho ikhishwa futhi yiziphi izici zesicelo sayo kwezolimo.
I-Sapropel nezindawo zayo
I-Sapropel idiphozi eqoqa phansi emzimbeni wamanzi amasha iminyaka eminingi. Kubantu abantu ababizwa ngokuthi i-sapropel kuthiwa nje udaka - leli gama lijwayele wonke umuntu. Iqukethe izinhlayiyana ezincane kunazo zonke zomhlaba wemifino nezilwane ngokufaka amaminerali ahlukahlukene. Lokhu kuhlanganisa i-nitrogen, i-phosphorus ne-potassium, i-iron ne-manganese, ithusi ne-boron, nezinye eziningi. Izindleko ezingezansi nazo zicebile amavithamini B , futhi ziqukethe ne-carotenoids eminingi ne-enzyme. Ngelinye igama, i-sludge evamile kakhulu idiphozi yezinto eziwusizo ezithonya kahle inhlabathi namasiko akhulayo. Ingasetshenziswa ngisho nangendlela yayo yemvelo njengomanyolo olula kakhulu engadini.
Ukuze kusetshenziswe umquba, i-sapropel igodliwe ngesilinganiso sezimboni, emva kwalokho esomile futhi siphathwe ngendlela efanele. Okukhiphayo kuyinto eyomile ngesimo se-powder, ongasifafaza umhlaba wonke noma wengeze emhlabathini.
I-sapropel ekhishwe ezikhungweni ezahlukene ihluke ngokuphawulekayo ekubunjweni, okuxhomeke ngokuqondile ekubunjweni kwenhlabathi yendawo. Kunezinhlobo ze-carbonate, organic, ferrous and siliceous ze-sapropel. Kungatholakala ngokuhlaziywa kwamakhemikhali. Ithinta ngokuqondile indlela i-sapropel yalezi zinhlobo ezisetshenziselwa ukukhula kwezitshalo. Ake sibheke indlela yokusebenzisa i-sapropel njengomanyolo.
Ukusebenzisa i-sapropel njengomanyolo
Ngokungafani ne-peat, umanyolo osekelwe ku-sapropel aqukethe izinto eziningi ezithwala i-nitrogenous, i-carbohydrate nama-amino acids. Lokhu kwenza i-sapropel izindlela ezisebenzayo, kodwa hhayi njalo. Uma i-peat isetshenziselwa ukucebisa inhlabathi ngama-humus, umanyolo kusuka ku-silt unomphumela olandelayo:
- ukungcola kwenhlabathi;
- i-aeration yayo eyengeziwe;
- ukuthuthukiswa kohlelo lwempande zezitshalo;
- ukwandisa isivuno;
- Ukuthuthukiswa kwezakhiwo zenhlabathi njengokungenisa nokugcina umswakama;
- ukwanda kokuqukethwe kwe-humus ezweni;
- Ukuhlanzwa kusuka ezigulwaneni nezifungi.
Enye inzuzo engenakuphika ye-sapropel njengomanyolo ukuhambisana nobungqongileyo. Ngokungafani namakhemikhali amaminerali amaminerali, kuphephile ngokuphelele kubantu nasezilwaneni. Futhi uma kuqhathaniswa nomquba, lapho kukhona khona izinambuzane ezinobungozi nembewu yokhula, okuqukethwe kwe-silt kule ndaba kuhluke kakhulu.
Mayelana nokusetshenziswa okusebenzayo kwe-sapropel, isetshenziselwa kokubili ukufaka umhlabathi ngokuqondile nokuququgquzela umquba . Esikhathini sokuqala, i-sapropel isetshenziselwa inani elingama-35-40 amathani ngehora elingu-1 yenhlabathi (okusanhlamvu) noma amathani angu-65-70 (imifino nezitshalo ezihlukahlukene ezimpande).
Kumele kuqashelwe ukuthi ukusetshenziswa kwe-sapropel ngokuvamile kungcono kunhlabathi enhlabathini enesihlabathi neyesihlabathi yamapayipi nezinhlobo ezimuncu. Kulesi simo, umphumela omuhle utholakala ngokunqunywa kokuqala kwenhlabathi enjalo.
