Kwimizamo yokucwangcisa igadi yekhitshi efumene umvuzo ngendlela yokuvuna okuninzi, umhlaba ufuna ukuchumisa ngezikhathi ezithile. Yaye mayeke abaxhasi bezolimo bezolimo bathi i-organic kuphela ayilimazi umhlaba kunye nomntu, abalimi abanolwazi bayazi kakuhle - izichumisi ze-mineral kunye nesicelo esisemgangathweni zikhuselekile ngokupheleleyo kumyezo kunye nempilo.
I-nitrogen fertilizer yomyezo
Ngentwasahlobo, xa izityalo zikwisigaba sokuphuhlisa esisebenzayo, zifumana isidingo esinzima se-nitrogen. Ukubonelela ngexabiso elifunekayo leli qumrhu linokubakho ukutsalwa kwentsholongwane ye-nitrogen fertilizer. Nazi ezinye izinto eziphambili:
- Urea (carbamide) - ukugqoka okuphezulu kunye nomxholo omkhulu we nitrogen. I-Urea ingasetyenziselwa zonke iintlobo zezityalo, zangaphambili zichithwa ngamanzi kwaye zisetyenziselwa zonyango kunye nezifo zonyango.
- I-ammonium nitrate yichumbo, equkethe i-nitrogen kwisithathu. Isetyenziselwa ukucwangcisa zonke izityalo, ngaphandle kwezityalo zengcambu.
- I-nitrate ye-sodium iyimfuyo yesitrogen esetyenziselwa ukugqoka okuphezulu kwezityalo zengcambu.
- I-nitrate ye-calcium isichumisi esisetyenziselwa ukugqoka ngaphezulu kwazo zonke izityalo zemifuno kunye neentyantyambo zeentyatyambo, kwakunye nezilimo zengcambu.
- I-ammonium sulphate iyimfuyo enesitrogen efanelekileyo kwizityalo ezikhetha inhlabathi enomthi.
Iifosentiri zamamineral fertilizer zomyezo
Ekupheleni kwehlobo nasekwindla, izityalo kufuneka zivuthwe ngokukhawuleza kwaye zilungiselele ubusika. Uncedo kule nto banako ukubeka i-phosphorus, ukunyuka komzimba ngokukhawuleza nokunyusa ukutshatyalaliswa kwezityalo ezibandayo. Isichumisi sesityuli esinexabiso elincinci lale kholeji libizwa ngokuthi "superphosphate" kwaye lisetyenziselwa ukuwa, ngexesha lokumba.
I-Potassium yezichumisi zedareli yomyezo
Izityuli ze Potassium zandisa umthamo wokuvuna, kwaye ziphucula kakhulu umgangatho wezityalo, ukubonakala kwazo nokugcina umgangatho. Ukongeza, ziphakamisa izakhiwo ezikhuselekileyo zezityalo kwaye zincede zigcine amanzi. Ngokuqhelekileyo iifotashi zetekisi zisetyenziselwa ukudibanisa nezinye iindidi zezichumisi zamaminerali.
