Qhov sib txawv tseem ceeb ntawm cov quav thiab cov organic yog cov quav chiv yog ib hom ntawm cov organic teeb meem uas tib neeg tsim thaum cov organic teeb meem yog cov carbon-nplua nuj compounds tsim nyob rau hauv cov av.
Nroj tsuag yog cov tsim khoom tseem ceeb hauv peb cov ecosystems. Yog li ntawd, lawv yog ib qho tseem ceeb rau kev muab zaub mov rau lwm yam tsiaj thiab koom nrog kev tswj hwm lub ntuj sib npaug. Cov nroj tsuag kuj xav tau zaub mov thiab dej kom loj hlob. Lawv nyob ntawm cov av rau zaub mov, dej thiab chaw nyob. Yog li ntawd, cov av yuav tsum muaj kev noj qab haus huv, thiab cov organic teeb meem yog qhov tsim nyog los tswj cov av zoo. Organic teeb meem yog cov tebchaw uas muaj cov pa roj carbon. Hauv av, muaj ntau hom organic teeb meem. Hauv qhov sib piv, Manure yog tib neeg tsim thiab muaj tag nrho cov as-ham tseem ceeb uas yuav tsum tau ua kom muaj kev noj qab haus huv hauv av. Raws li, organic teeb meem thiab quav quav yog ob lub ntsiab lus uas tseem ceeb heev hauv av biology thiab kev ua liaj ua teb.
Dab tsi yog Manure?
Manure yog cov av-enriching organic teeb meem uas muaj ntau yam tseem ceeb as-ham. Yog li ntawd, manure yog ib tug zoo fertilizer. Nws suav nrog nitrogen, phosphorous, poov tshuaj raws li cov ntsiab lus tseem ceeb thiab yog li cuam tshuam nrog av enrichment. Manure yog peb hom; tsiaj manure, cog manure thiab compost. Tsiaj quav quav yog cov zis thiab quav tsiaj ntawm cov tsiaj hauv av. Yog li ntawd, hom chiv no feem ntau sau los ntawm thaj chaw ua liaj ua teb uas tsa nyuj, nees thiab npua, thiab lwm yam. Hom tsiaj thiab lawv cov qauv pub ncaj qha cuam tshuam rau cov khoom noj muaj pes tsawg leeg ntawm tsiaj quav. Txij li thaum lawv muaj siab ammonia thiab nitrogen tebchaw, nws tsis pom zoo kom siv ncaj qha rau hauv av vim nws tuaj yeem cuam tshuam cov nroj tsuag. Yog li ntawd, cov chiv no yuav tsum tau tso tseg kom muaj hnub nyoog li ob peb lub hlis ua ntej siv.

Nroj Tsuag yog cov khoom noj ntxiv los ntawm cov nroj tsuag rau hauv av thaum lawv loj hlob. Tshwj xeeb tshaj yog legume nroj tsuag uas muaj hauv paus nodules muaj symbiotic nitrogen-kho kab mob. Cov nroj tsuag zoo li no tau cog rau qee lub sijhawm hauv thaj chaw thaj av kom txhawb cov av thaum npaj cog qoob loo. Kev lwj cov nroj tsuag thiab tsiaj txhu tsim cov chiv ua chiv. Xws li decomposition tshwm sim nyob rau hauv moist thiab kub tej yam kev mob. Compost muaj ntau cov as-ham tseem ceeb rau kev noj qab haus huv ntawm cov nroj tsuag. Li no, nws yog ib qho zoo heev ntawm chiv.
Dab tsi yog Organic Matter?
Cov teeb meem organic yog sib sau ua ke los ntawm cov khoom sib txuas los ntawm cov tsiaj, nroj tsuag thiab cov kab mob. Tsis zoo li cov quav, cov organic teeb meem tsis yog cov kab mob nyob hauv av, thiab tsis muaj cov tshuaj ntxiv rau hauv av los ntawm cov nroj tsuag thiab tsiaj txhu. Nws yog qhov tshwm sim ntawm decomposition ntawm xws li tshuaj los ntawm microorganisms.
Daim duab 02: Organic Matter
Microbial decomposed organic teeb meem yog humus. Zoo ib yam li cov quav, cov organic teeb meem muaj ntau yam khoom noj. Kev sib pauv ntawm cov as-ham los ntawm cov organic teeb meem thiab av yog qhov tseem ceeb rau cov av enrichment thiab fertility. Tsis tas li ntawd, nws cuam tshuam rau cov tshuaj lom neeg ntawm cov av, nws muaj peev xwm tuav cov dej noo, kev loj hlob ntawm cov nroj tsuag thiab kev ua haujlwm lom ntawm cov kab mob hauv av.
Dab tsi yog qhov zoo sib xws ntawm Manure thiab Organic Matter?
- Manure thiab organic teeb meem nce av fertility.
- Ob leeg txhawb nqa av.
- Kuj, ob hom muaj ntau yam khoom noj.
Qhov txawv ntawm Manure thiab Organic Matter yog dab tsi?
Manure yog ib hom organic teeb meem thiab cov chiv zoo uas muaj nitrogen, phosphorus thiab potassium. Ntawm qhov tod tes, cov organic teeb meem yog cov khoom sib txuas ntawm cov pa roj carbonic uas tau los ntawm cov nroj tsuag, tsiaj txhu, kab mob, thiab lwm yam. Yog li, qhov no yog qhov sib txawv ntawm cov quav thiab cov organic teeb meem.
Tsis tas li ntawd, muaj peb yam tseem ceeb ntawm cov quav, tsiaj quav, cov quav cab, thiab cov quav chiv. Organic teeb meem yog ib hom uas yog humus. Yog li, qhov no yog lwm qhov sib txawv ntawm cov chiv thiab cov organic teeb meem. Tsis tas li ntawd, manure feem ntau yog tib neeg tsim thaum cov organic teeb meem yog qhov tshwm sim ntawm microbial decomposition.
Summary – Manure vs Organic Matter
Manure yog av enriching organic teeb meem uas muaj cov as-ham tseem ceeb. Yog li ntawd, manure yog ib tug zoo fertilizer. Manure yog peb hom; tsiaj quav quav, cog quav, thiab compost. Tsiaj txhu muaj pes tsawg leeg sib txawv raws li hom tsiaj thiab cov qauv pub. Tsis zoo li cov quav, cov organic teeb meem tsis yog cov kab mob nyob hauv av, thiab tsis muaj cov tshuaj ntxiv rau hauv av los ntawm cov nroj tsuag thiab tsiaj txhu. Nws yog qhov tshwm sim ntawm decomposition ntawm xws li tshuaj los ntawm microorganisms. Ob qho quav thiab organic teeb meem nce kev noj qab haus huv thiab fertility ntawm av. Yog li, qhov no qhia txog qhov sib txawv ntawm cov quav thiab cov organic teeb meem.
