Qhov twg muaj lub sij hawm ua chiv ntev dua, dej- cov chiv chiv nrog macronutrients lossis cov chiv chiv?

Dej- cov chiv chiv thiab cov chiv sib xyaw yog ob hom chiv sib txawv. Dej- cov chiv uas muaj kuab lom tsis yog tsuas yog muaj cov khoom noj muaj txiaj ntsig zoo thiab muaj cov ntsiab lus siab, tab sis kuj tsis tsim lossis muaj precipitates tom qab yaj hauv dej. Cov dej loj loj- cov chiv ua kua dej feem ntau muaj peb lub ntsiab lus tseem ceeb ntawm nitrogen, phosphorus thiab potassium, thiab tseem ntxiv cov ntsiab lus nruab nrab thiab kab. Cov dej loj loj- cov chiv soluble yog soluble hauv dej sai sai thiab yooj yim absorbed thiab siv ncaj qha los ntawm lub hauv paus system ntawm cov qoob loo. Lawv yog hom ceev- ua chiv. Hom kev ceev no - ua chiv muaj cov nyhuv sai, muaj zog fertility, thiab lub sij hawm luv luv.
Compound chiv tuaj yeem muab ob lossis ntau lub ntsiab lus ntawm cov as-ham rau cov qoob loo thiab txhawb kev sib cuam tshuam ntawm cov as-ham hauv cov qoob loo. Cov chiv chiv feem ntau suav nrog cov chiv nrog nitrogen, phosphorus thiab potassium. Compound chiv muaj complex compositions, ntau yam thiab tseem ceeb sib txawv ntawm cov khoom. Fertilizers xws li ammonium phosphate, potassium dihydrogen phosphate thiab potassium nitrate, thaum siv rau hauv av, dhau los ua cov txheej txheem biochemical decomposition. Los ntawm kev ua ntawm cov av microorganisms, cov chiv tau decomposed rau hauv cov as-ham uas cov qoob loo tuaj yeem nqus tau thiab siv tau. Yog li ntawd, lub sij hawm ntawm lawv cov hauj lwm zoo yog ntev tshaj li cov dej -soluble chiv.
