Fulvic Acid 60% CAS: 479-66-3 Chaw Tsim Khoom Siv

Fulvic Acid 60% ua cov nroj tsuag biostimulants feem ntau yog tsim los ntawm biodegradation ntawm lignin uas muaj cov nroj tsuag organic matter [14]. Fulvic acids uas ib txwm nyob hauv cov kua, tshwj xeeb tshaj yog ntawm pH ntawm cov av ua liaj ua teb tsim khoom, kuj pab txhawb rau cation pauv peev xwm ntawm cov av [14, 15]. Vim yog qhov solubility ntawm fulvic acids hauv dej thiab qhov tseeb tias nws tuaj yeem yooj yim leached tawm, nws feem ntau tsuas yog nyob rau hauv cov concentration qis heev [0.2-1% w / v] hauv leonardite, peat, thiab compost thiab lwm yam, qhov chaw. Yog li ntawd qee lub tuam txhab yuav qhuav fulvic acids rau hmoov [14]. Fulvic acid ua cov organic chiv, yog cov khoom siv tsis muaj tshuaj lom thiab cov dej binder uas ua rau kom nqus tau ntau tshaj plaws los ntawm nplooj thiab txhawb cov nroj tsuag tsim khoom [14]. Fulvic acid yog cov organic thiab ntuj electrolyte. Nws tau ua pov thawj lub peev xwm los txhim kho qhov muaj thiab adsorption ntawm cov as-ham.
