Mayeso a Dothi ST-4

Kufotokozera Kwachidule:

Kuyesa nthaka ndi kusanthula kofunikira kwa ulimi ndi chilengedwe komwe kumagwiritsidwa ntchito poyesa mankhwala ndi zinthu zakuthupi za nthaka. Mwa kusanthula chitsanzo choyimira mu labotale, kumapereka deta yofunika kwambiri pa zizindikiro zazikulu za chonde monga pH ya nthaka, kuchuluka kwa michere yofunika (monga nayitrogeni, phosphorous, ndi potaziyamu), ndi kuchuluka kwa zinthu zachilengedwe.

Pulatifomu yoyezera ya m'manja imagwiritsa ntchito ukadaulo waposachedwa kwambiri wa digito komanso ukadaulo wozindikira wapadziko lonse lapansi kuti ipange chowunikira chatsopano chanzeru cha m'manja.

Chowunikiracho chimagwiritsa ntchito chowonetsera chamadzimadzi chamitundu yonse, chomwe chimatha kuwonetsa kuwerenga nthawi yomweyo. Nthawi yomweyo, chimagwiritsa ntchito njira yodziwira yomwe idapangidwa ndi chipangizo cha digito cha mafakitale akuluakulu apadziko lonse lapansi, chomwe chingathe kukhala ndi mphamvu zambiri komanso kubwerezabwereza bwino. Chipolopolocho chimapangidwa ndi pulasitiki yophatikizika yamphamvu kwambiri yogwiritsidwa ntchito m'mafakitale, yomwe ili ndi mphamvu zambiri.
