Kukonzanso nthaka: momwe mungamvetsetse bwino ntchito ya humic acid ndi fulvic acid

Udindo wa humic acid ndi fulvic acid:
Magulu ogwira ntchito mu humic acid (makamaka magulu a carboxyl ndi magulu a phenolic hydroxyl) amatha kupatsa ma ayoni a haidrojeni, kotero kuti humic acid imawonetsa kufooka kwa acidity ndi reactivity yamankhwala, ndipo imakhala ndi mphamvu yosinthira ma ion ndi mgwirizano wovuta (chelating). Mitundu ya quinone, carboxyl ndi phenolic hydroxyl ya humic acid imapangitsa kuti ikhale yogwira ntchito. "Ntchito zisanu" za humic acid paulimi (kukonza nthaka, kuonjezera mphamvu ya feteleza, kulimbikitsa kukula, kupititsa patsogolo kupanikizika ndi kuwongolera khalidwe) zakhala zikutsogolera kagwiritsidwe ntchito ndi kupita patsogolo kwa humic acid m'munda waulimi.

Fulvic acid ndi mankhwala a humic acid okhala ndi ntchito zambiri komanso phindu lalikulu lazachuma. Mpaka pano, idakali ndi msika waukulu komanso wopikisana nawo pakukula kwa zomera, anti-stress agents, feteleza wamadzimadzi, kukonzekera mankhwala, ndi zodzoladzola. Ntchito ya "four-agent" ya fulvic acid paulimi (yolimbana ndi chilala, chowongolera kukula, synergist yotulutsa pang'onopang'ono mankhwala ophera tizilombo) ndi yachikale, ndipo ndi yapadera ngati yolimbana ndi chilala.

Kupanga zinthu zatsopano zokhudzana ndi humic acid ndi fulvic acid:
Humic acid ali ndi kuthekera kwakukulu kopanga zida zatsopano chifukwa cha mawonekedwe ake obiriwira, chilengedwe komanso organic. Kwa feteleza, humic acid imatha kukhala zinthu zophatikizika (mamolekyu akulu, apakati ndi ang'onoang'ono), zida zogwirira ntchito (zotulutsa nayitrogeni, phosphorous yamoyo, kukwezedwa kwa potaziyamu), ndi zinthu zosagwira kupsinjika (monga kukana chilala, kukana kuzizira, kukana madzi, matenda. ndi kukana tizilombo toyambitsa matenda), ikhoza kukhala chinthu cha chelating, ikhoza kukhala chinthu chapadera, ndi zina zotero.

Fulvic acid ndi gawo losungunuka m'madzi la humic acid. Chifukwa cha kulemera kwake kwa mamolekyulu, pali magulu ambiri a acidic, kusungunuka kwabwino, komanso kugwiritsa ntchito kwambiri. Kwa feteleza, fulvic acid imatha kukhala zida zoyengedwa (monga mamolekyu ang'onoang'ono, zochita zambiri, zokhutira), zitha kukhala zida zolimbana ndi kupsinjika (monga kukana chilala cha zomera, kukana kuzizira, kukana madzi, matenda ndi tizirombo, etc.), ndipo ikhoza kukhala zinthu za chelating zitha kukhala zakuthupi zapadera kapena zina.
