Ulimi ndi ntchito yovuta kwambiri yomwe imafuna kusamalidwa kosalekeza kuti mbewu zizikhala zathanzi. Limodzi mwazovuta zazikulu zomwe alimi amakumana nazo ndikuletsa udzu. Udzu umapikisana ndi mbewu pa zinthu zofunika monga kuwala kwa dzuwa, zopatsa thanzi m'nthaka ndi madzi. Pofuna kuthana ndi vutoli, nsalu zophimba pansi (zomwe zimadziwikanso kuti zolepheretsa udzu) zakhala chida chofunikira kwa alimi.
Garden pansi chophimba nsalundi chinthu cholowa chopangidwa ndi polypropylene yolukidwa kapena yosalukidwa. Cholinga chake chachikulu ndikuletsa kukula kwa udzu popanga chotchinga pakati pa nthaka ndi chilengedwe chakunja. Mwa kutsekereza kuwala kwa dzuŵa kuti lisafike namsongole, nsaluzi zimalepheretsa kupanga photosynthetic, ndipo pamapeto pake zimalepheretsa kukula kwake.
Kugwiritsa ntchito nsalu yotchinga m'munda kumapatsa alimi zabwino zingapo. Choyamba, imachepetsa kufunika kwa mankhwala ophera udzu, ndikupangitsa kuti ikhale yankho logwirizana ndi chilengedwe. Pochepetsa kugwiritsa ntchito mankhwala ophera udzu, alimi amatha kuteteza zachilengedwe zozungulira ndikuwonetsetsa kuti anthu ndi nyama zakuthengo ali ndi thanzi labwino.
Kuphatikiza apo, nsalu yotchinga pansi pamunda imagwira ntchito ngati insulator, yowongolera kutentha kwa nthaka ndi chinyezi. Izi ndizothandiza makamaka nyengo yotentha, monga mafunde otentha kapena mvula yambiri. Pokhala ndi nthaka yabwino, nsaluyo imathandiza kulimbikitsa kukula kwa mbewu ndi zokolola, zomwe zimapangitsa kuti pakhale ntchito zaulimi.
Kuonjezera apo, nsalu yophimba pansi pamunda imalepheretsa kukokoloka kwa nthaka. Imagwira ntchito ngati nsanjika yoteteza, kuteteza kukokoloka kwa mphepo ndi madzi posunga tinthu tating'ono. Izi ndizofunikira makamaka m'madera otsetsereka kapena madera omwe kugwa mvula yambiri. Poteteza dothi la pamwamba, alimi amatha kusunga malo achonde omwe amameramo mbewu zawo.
Kuyika nsalu yophimba pansi pamunda ndi njira yosavuta. Choyamba, malo oti aphimbidwe ayenera kuchotsedwa udzu kapena zomera zomwe zilipo kale. Kenaka, tambani nsalu pamwamba pa nthaka, kuonetsetsa kuti ikuphimba kwathunthu malo okonzekera. Kenako imatetezedwa ndi mitengo kapena m'mphepete kuti mphepo isasunthike. Pomaliza, mbewu kapena mbewu zitha kulimidwa kudzera m'mabowo a nsalu, zomwe zimalola kukula kolamulirika.
Mwachidule, nsalu zophimba pansi pamunda ndi chida chamtengo wapatali kwa alimi polimbana ndi udzu. Kukhoza kwake kuletsa kukula kwa udzu, kusunga chinyezi m'nthaka ndikuletsa kukokoloka kumapangitsa kuti ikhale gawo lofunikira pazaulimi zamakono. Pokhazikitsa njira yokhazikikayi, alimi amatha kuchulukitsa zokolola, kuchepetsa kudalira mankhwala ophera udzu, ndikupeza mbewu zathanzi.
