Hauv kev ua liaj ua teb, chelation yog siv los txhim kho cov nroj tsuag kev noj qab haus huv los ntawm kev ua kom muaj cov as-ham ntxiv rau cov nroj tsuag. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov av uas tsis muaj cov as-ham, xws li hlau lossis zinc.
Chelating agents yog siv los chelate micronutrients, xws li hlau, tooj liab, zinc, thiab manganese, ua rau lawv soluble ntau thiab muaj rau cov nroj tsuag uptake. Cov txheej txheem no tuaj yeem txhim kho cov nroj tsuag kev loj hlob thiab kev loj hlob, nrog rau nce qoob loo thiab zoo.
Piv txwv li, hlau deficiency yog ib qho teeb meem nyob rau hauv ntau cov qoob loo, tshwj xeeb tshaj yog nyob rau hauv alkaline av. Nyob rau hauv cov ntaub ntawv no, hlau chelates yuav siv tau rau hauv av los yog foliage ntawm ntau yam qoob loo los txhim kho hlau uptake rau cov qoob loo. Ib yam li ntawd, zinc chelates tuaj yeem siv los daws cov zinc deficiency hauv cov qoob loo. Ua ntej siv cov khoom los kho cov khoom noj tsis txaus, nco ntsoov sab laj nrog koj tus kws kho tsiaj. Lawv tuaj yeem pab koj nrhiav kev daws teeb meem thiab tsim cov phiaj xwm tshwj xeeb rau koj cov kev xav tau.
