Xa abathengi bahlala bavumela i-NPK compound fertilizers ukuziyithenga, kubalulekile ukuzicinga ngokulinganisa oku: i-NPK okanye ubungakanani bomthwalo wokugcina, okuyinto eyinkulu yokuqondisa amaqhezu ayo ase- nitrogen, phosphorus kunye ne-potassium kwizinto ezithengwa.

Ukhombiso

Izinombolo zase-NPK fertilizers zibonisa ukuba zingakanani yezo zomthwalo zisemthwalenini. Umzekelo, umthwalo wokugcina othi 10-20-10 unakha i-nitrogen ngama-10%, i-phosphorus ngama-20% kunye ne-potassium ngama-10%.

Ngathi

Xa umthengi ufuna ukuthenga i-NPK compound fertilizers ukuthumela phandle, kufuneka ucinge ngokulinganisa umphathi wemiti ubungakanani bomthwalo wokugcina kunye nezinqulungwane. I-NPK fertilizers ziqondwa ngamathathu amakhulu amathathu—i-nitrogen (N), i-phosphorus (P), kunye ne-potassium (K).

Izicwangciso

Kodwa ukuba uyazi ukuba ubungakanani nobunzima bezinqulungwane bungcono, manje kufuneka uhlale ujonge indlela eyahlukeneyo yokulinganisa i-NPK fertilizers ngokulinganisa ubungakanani. Le bifen insecticide yindlela ingaba yinkcinane yobugcwele ngoba akukho zonke izibhantshana zibalulekile ngokufanayo. Indlela enkulu yokuqiniseka ukulinganisa xa uvumela i-tractors kukufunda izirabi zaba-farmers kunye nabathengi.
