Dothi ndi feteleza: gwero la moyo umene umadyetsa nkhaka

Dothi la wowonjezera kutentha ndi malo achonde kuti nkhaka zimere mizu ndikukula. Inchi iliyonse ya dothi yakonzedwa bwino ndikuwongoleredwa. Anthu amasankha gawo lotayirira kwambiri, lachonde komanso lotayidwa bwino kuchokera kumitundu yambiri ya dothi, kenaka amawonjezera zinthu zambiri zachilengedwe monga kompositi yovunda ndi dothi la peat ngati chuma. Zinthu zachilengedwezi zili ngati ufa wamatsenga, zomwe zimapangitsa nthaka kukhala ndi madzi amatsenga komanso kusunga feteleza, zomwe zimapangitsa kuti mizu ya nkhaka itambasule momasuka ndikuyamwa zakudya.
Feteleza ndi ntchito yasayansi komanso yovuta. Nkhaka zisanabzalidwe, feteleza wapansi amakhala ngati nyumba yosungiramo zinthu zopatsa thanzi yokwiriridwa pansi kwambiri. Manyowa osiyanasiyana monga feteleza wachilengedwe, feteleza wa phosphorous, ndi feteleza wa potaziyamu amafananizidwa ndi wina ndi mzake kuti akhazikitse maziko olimba a kukula kwa nkhaka. M'nyengo ya kukula kwa nkhaka, njira yothirira madzi imakhala ngati wolima munda wakhama, akupereka "kasupe wa moyo" mosalekeza - pamwamba pa nkhaka. Feteleza wa nayitrojeni, feteleza wapawiri ndi feteleza wa trace element amaperekedwa molondola ku mizu ya nkhaka kudzera mu njira yothirira kudontha, kuwonetsetsa kuti atha kupeza zakudya zopatsa thanzi pakukula kulikonse. Chiwembu chabwino ichi cha feteleza sikuti chimangopangitsa kuti nkhaka zikule bwino, komanso zimapewa mavuto a dothi la salinization omwe amayamba chifukwa cha umuna wambiri. Zili ngati kuvina kojambulidwa mosamala, ndipo mayendedwe aliwonse amakhala oyenera.
