Vuto lalikulu limene pafupifupi mlimi aliyense ankakumana nalo linali nsonga za adyo zachikasu m’chilimwe. Zikuoneka kuti izi zikhoza kupewedwa podziwa malamulo ochepa chabe.
Ngati chomera patsamba lanu mwadzidzidzi chinayamba kutembenukira chikasu, ndiye nthawi yoti mudyetse, ndikutembenukira kumankhwala owerengeka kuti muthandizidwe. Ndizinthu izi zomwe zili zabwino chifukwa zilibe mankhwala - mankhwala ophera tizilombo ndi herbicides.
Ngati nsonga zikuyamba kukhala zachikasu, ichi ndi chizindikiro cha njala ya nayitrogeni. Chimodzi mwazosankha za umuna wothandiza ndi yankho lomwe lingakonzedwe motere: 10 g ya carbamide (aka urea) imatengedwa kwa malita 30 a madzi. Chinthucho chidzasungunuka kwathunthu mumadzimadzi. M'pofunika kusonkhezera zonsezi ndi kubweretsa okwana voliyumu.
Ikani chosakaniza chomwe chimabwera mumtsuko wothirira ndikupopera mabedi adyo nawo. Tiyenera kukumbukira kuti kudyetsa kungathe kuchitidwa ndi kuthirira mwachindunji kwa zomera pansi pa muzu, ndi kupopera mbewu mankhwalawa.
Palinso zinthu zina zingapo zomwe zingagwiritsidwe ntchito kudyetsa, zomwe zingathandize kuteteza adyo ku chikasu. Izi zikuphatikiza zinthu zotsatirazi:
phulusa lamatabwa;
superphosphate;
mchere wa potaziyamu;
potaziyamu sulphate;
tincture wa ayodini.
Mu May, adyo amafunikira zowonjezera zowonjezera za nayitrogeni, ndipo mu June, zowonjezera potaziyamu-phosphorous.
