(1) i-nitrogen: izakhi ze-nitrogen zomsoco njengengxenye eyinhloko kamanyolo, okuhlanganisa i-ammonium bicarbonate, urea, iphinikhodi ye-ammonium, i-ammonia, i-ammonium chloride, i-ammonium sulfate, njll.
(2) p: izakhi zomsoco njengengxenye eyinhloko kamanyolo, kuhlanganise ne-superphosphate evamile, umanyolo we-calcium magnesium phosphate, njll.
(3) k: izakhi zokudla okunomsoco we-potassium njengengxenye eyinhloko yomanyolo, ukusetshenziswa akukuningi, izinhlobo eziyinhloko ziyi-potassium chloride, i-potassium sulphate, i-potassium nitrate, njll.
(4) Umanyolo ohlanganisiwe noxubile, umanyolo uqukethe izakhi ezimbili kwezintathu zomanyolo (i-nitrogen, i-phosphorus ne-potassium) inhlanganisela kanambambili kanye nomanyolo oxubile futhi oqukethe i-nitrogen, i-phosphorus ne-potassium izakhi ezintathu ze-ternary compound kanye nomanyolo oxubile.Ukukhuthazwa kukamanyolo oxubile ngokushesha ezweni lonke.
(5) izakhi ezithile ku-trace element Umanyolo nomanyolo, njengangaphambili aqukethe i-boron, i-zinc, insimbi, i-molybdenum, i-manganese, ithusi kanye nezinye umanyolo we-trace element, lezi zamuva ezifana ne-calcium, i-magnesium, umanyolo wesibabule.
