Izakhimzimba ezintathu eziqakathekileko ezisetjenziswa zintjalo yi-Nitrogen (N), Phosphorous (P) kanye ne-Potassium (K). Lokha nawuthatha isiqunto sokobana usebenzise siphi isivundisi kunezakhimzimbi eziqakathekileko ezintathu ezenzwe zabayihlanganisela begodu zibonakala ngeenomboro ezintathu ezitlolwe ngazo eskhameni sazo eziyiphawu le-N P K eyenzwe ngazo kanye nesilinganiso sehlanganisela leyo.
Ukutlhadlhulwa kwe-NPK
Iphawu le-NPK esivundisini litlhadlhula amaphesendi wezakhamzimba wesinye nesinye esikiyo Inomboro engamva kwesilinganiso etlolwe hlangana kwembayana (isibonelo 27) yiphesende lehlanganisela epheleleko ejamele izakhimzimba eziqakathekileko ezintathu, i- N, P kanye ne-K.Njeke, eskhameni eseyi-100 kg ye- 2:3:4 (27)
Njeke:
I-27 itlhadlhula bona i-27% eseskhameni nanyana i-27 yamakhilogramu ejamele ithothali ye- N, P kanye ne- K. Islinganiso senziwe ngenquntu ezilithoba ngokufaka i-2+3+4 begodu nawuphindaphinda. U-9 ku-27 isilinganiso senqenye yinye yesilinganiso ijamele u-3.
I-2 nakaphindwaphindwa ngo-3 yi-6% Nitrogen (N) nanyana i-6 kilograms.
Kune -3 njeke yi-9% Phosphorous (P) nanyana i- 9 Kilograms
Kune -4 njeke -12% Potassium (K) nanyana -12 yamakhilogramu
Enye i-73 khilogramu ye-100 khilogramu yesivundisi yenziwe nge-filler elements eyenza kube lula ukujamelana nesivundisi,i-carrier element eyenza i- N, P kanye - K itholakala emirajini yentjalo ehlabathini kanye namanye ama-trace elements afana ne-Copper, Zinc, Boron, Manganese kanye ne-Magnesium engasetjenziswa eentjalweni.
