Peb txhua tus paub tias cov nroj tsuag xav tau cov as-ham kom vam meej, thiab ib qho ntawm cov khoom noj tseem ceeb tshaj plaws yog NPK. NPK sawv cev rau nitrogen, phosphorus, thiab potassium, thiab lawv yog peb lub ntsiab macronutrients uas cov nroj tsuag xav tau kev loj hlob zoo.

Kev siv cov chiv NPK txoj cai yog qhov tseem ceeb rau kev ua kom koj cov nroj tsuag noj qab haus huv thiab tsim tau, thiab nws yog ib qho tseem ceeb kom nkag siab tias txhua yam zaub mov ua rau koj cov nroj tsuag. Nitrogen yog qhov tseem ceeb rau kev loj hlob ntawm nplooj thiab stems, phosphorus yog qhov tseem ceeb rau kev loj hlob hauv paus thiab paj, thiab potassium pab cov nroj tsuag tiv thaiv kab mob thiab kev ntxhov siab.

Txawm hais tias txhua hom nroj tsuag muaj qhov sib txawv ntawm NPK, ntawm no yog daim ntawv qhia NPK muaj txiaj ntsig los muab tswv yim rau koj.

Dab tsi ntawm cov chiv koj yuav tsum siv rau ntau hom nroj tsuag:

- Zaub: Siv cov chiv sib npaug nrog cov nitrogen, phosphorus, thiab poov tshuaj sib npaug, xws li 10-10-10 lossis 20-20-20.
