Gulu la humic acid lomwe limagwira ntchito mu potaziyamu humate limatha kuyamwa ndikusunga ayoni wa potaziyamu, kupewa madzi kutayika mumchenga komanso kutayikira nthaka, komanso kupewa potaziyamu ndi dothi louma. Kuphatikiza apo, magawo ena a potaziyamu humate ndi otsika kwambiri a humic acid monga fulvic acid, yomwe imakhudza potaziyamu wokhala ndi silicate, potaziyamu feldspar, ndi mchere wina. Ikhoza kuwola pang'onopang'ono kuti ichulukitse kutulutsa kwa potaziyamu ndikuwonjezera potaziyamu womwe ulipo. Kugwiritsa ntchito feteleza wa potashi kumawonjezeka ndi 87% -95% kuposa feteleza wamba wa potashi, zomwe zimapangitsa kuti feteleza azigwira bwino ntchito, zokolola, komanso zabwino. Zili ndi zotsatira zapadera pophatikiza kugwiritsa ntchito nthaka ndi chakudya; kuyendetsa nthawi yayitali komanso kuchitapo kanthu mwachangu; Kusunga madzi ndi zotsatira zosungira feteleza, ndi zina zotero, zotsatira zake, zimaphatikiza zabwino za fetereza wopanda manyowa ndi manyowa akumunda ndipo ndizowaposa, ndipo zili ndi ntchito yabwino yotulutsa michere Ndi feteleza woyendetsedwa bwino, kotero kuti michere kumayambiliro sikudzakhala kochuluka kwambiri, ndipo michereyo siyikhala yotsika kwambiri pambuyo pake, ndipo mphonje ya feteleza ndiyokhazikika. Mtengo womasuliranso ungasinthidwe ndi njira zathupi, zamankhwala, komanso ukadaulo wazachilengedwe kuti muzindikire njira ziwiri zosinthira kutulutsa mwachangu komanso kumasulidwa kwanthawi zonse.

Itha kugwiritsidwa ntchito ngati kusintha kwa nthaka. Sinthani dongosolo la nthaka. Lonjezerani mphamvu yosinthira nthaka, kulimbikitsa kupsinjika kwa nthaka, makamaka kuchepetsa mchere wambiri munthaka yamchere. Lonjezerani kuyamwa kwa michere ndikuwonjezera humus m'nthaka. Pewani kuwonongeka kwa nthaka ndi ayoni heavy metal ndi zinthu zina zovulaza.
