Kompositi ndi Earthwork ndi Screening Bucket

Kanema wotsatira ndi koyambirira kompositi ndi ntchito yapadziko lapansi poyang'ana ndowa.

Kompositi ndi njira yazachilengedwe yomwe imagwiritsa ntchito tizilombo tating'onoting'ono monga mabakiteriya, actinomycetes, ndi mafangasi omwe amafalitsidwa kwambiri m'chilengedwe kuti athe kuwongolera kusintha kwa zinthu zachilengedwe zomwe zimawonongeka kukhala humus wokhazikika pansi pamikhalidwe ina yokumba. njira yowotchera. Kuti ifulumizitse kuwonongeka, musanayambe kupanga kompositi, m'pofunika kugwiritsa ntchito chidebe cha sieving kuti musefa zopangira kuchotsa zinyalala monga magalasi osweka, miyala, ndi matailosi. Zinthu zotsalazo zimaphwanyidwa kuti ziwonjezeke kukhudzana ndi kuwongolera kuwonongeka.

Earthwork ndi imodzi mwa mitundu ikuluikulu ya ntchito yomanga, kuphatikiza kukumba konse kwa nthaka (miyala), kudzaza, mayendedwe, ngalande, mvula ndi zina zotero. Kuchuluka kwa ntchito zapadziko lapansi ndi zazikulu, zomangira zimakhala zovuta, ndipo zimakhudzidwa kwambiri ndi geological, hydrological, meteorological ndi zina. Chidebe choyang'ana chikhoza kuphwanya miyala pamalopo kuti ipange miyala yabwino yophwanyidwa, yomwe imatha kubwezeredwa mwachindunji, zomwe zimathandizira kuvutikira kwa nthaka.
