Marka aad gurato dalagga aasaasiga ah, dhulka oo bannaan maaha guul — ciidda way nabaad-guurta, way qalashaa, oo nafaqada way lumin. Cover crops (dalagga daboolaha) waxay daboolan dhulka, ku biiriyaan nitrogen-ka bilaashka ah, oo kor u qaadaan wax-soosaarka dalagga xiga 10–30%. Bare soil between crops erodes, dries out, and loses nutrients. Cover crops protect the soil, fix free nitrogen, and lift the next cash crop's yield 10–30%. التربة العارية تتعرّى وتفقد المغذيات. محاصيل الغطاء تحمي التربة وتثبت النيتروجين وترفع إنتاج المحصول التالي 10–30%. Udongo wazi hupoteza virutubisho. Cover crops huongeza mavuno 10–30%.

Bilow gu'ga: isla markaad guratay dalagga deyrta, beero cover crop-ka kahor inta aanan jiilaalku gaadhin. Intercrop: kala dhex beer cover crop-ka iyo dalagga aasaasiga ah (tusaale: galley + cowpea). Daboolaha xilliga jiilaalka: waxa loo isticmaalaa noocyada abaaraha ka adkaysta (cowpea, lablab). After harvest: sow immediately after the cash crop is harvested, before dry season. Intercrop: grow cover crops between rows of the main crop (e.g., maize + cowpea). Dry-season cover: use drought-tolerant species (cowpea, lablab). بعد الحصاد: ازرع فوراً. Baada ya mavuno au kuotesha.
