Feteleza zachikhalidwe zaulimi zimaphatikizapo urea, superphosphate, ndi feteleza wapawiri. Pazaulimi zamakono, feteleza osungunuka m'madzi amasiyana ndi feteleza wamba ndipo amatenga malo pamsika wa feteleza chifukwa cha zabwino zamitundu yosiyanasiyana yazakudya komanso kuyamwa kwakukulu komanso kutembenuka kwakukulu. Kotero, ubwino wa feteleza wosungunuka m'madzi ndi wotani? Kodi mtengo wake ndi wotani poyerekeza ndi feteleza wamba?
Mphamvu yake yosungunuka m'madzi imatha kusungunuka ikakumana ndi madzi, ndipo sipadzakhala zinthu zotsalira. Ikhoza kusungunuka kwathunthu m'madzi. Kudzera mu ulimi wothirira, kupopera mbewu mankhwalawa, etc., izo mwachindunji amachita pa mizu ndi masamba pamwamba mbewu kukwaniritsa cholinga cha mkulu-mphamvu magwiritsidwe. Komabe, pali zonyansa zosasungunuka m'madzi mu feteleza wamba, zomwe zimafunika kusungunuka ndikusefedwa musanayambe kuthirira ndi feteleza. Kuyamwidwa kwa michere ndi mbewu kudzakhudzidwanso ndi zodetsa. Mukamagwiritsa ntchito feteleza wachikhalidwe, ndikofunikira kumwaza feteleza granules pamizu ya mbewu pasadakhale, kenako kuthirira. Njira ya umuna ndi yovuta ndipo mayamwidwe a mbewu si abwino. Poyerekeza ndi feteleza osungunuka m'madzi omwe amagwiritsidwa ntchito pano, ndizovuta kwambiri. Manyowa amakono osungunuka m'madzi ali ndi mitundu yosiyanasiyana. Pogwiritsa ntchito njira ya feteleza wa lamba wamadzi ndi kuphatikiza kwa feteleza wamadzi, zakudya zambiri zolemera zimatha kuyamwa ndi mbewu, ndipo kutembenuka kwa mayamwidwe kumaposa kawiri kuposa feteleza wamba, mpaka 80% -90%.
Poyerekeza ndi feteleza wamba, feteleza wosasungunuka m'madzi amakhala ndi michere yambiri. Sikuti muli nayitrogeni, phosphorous, ndi potaziyamu zofunika kukula mbewu, komanso wolemera mu sing'anga ndi kufufuza zinthu, makamaka anawonjezera mwapadera "wolemera yaying'ono-carbon", amene ntchito Mbewu ndi mbali yofunika popereka yaing'ono molekyulu carbon. zinthu zothetsera vuto la njala ya carbon carbon.
