Growing Cabbage in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Cabbage. Garissa's soil (pH 7.96, alkaline) gives Cabbage a suitability score of 0/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Cabbage (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Cabbage's preferred 5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Cabbage prefers clay loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Cabbage's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Cabbage is the #87 soil match of the 106 crops we assess for Garissa County. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Garissa's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Garissa's nitrogen (0.61 g/kg) is 51% of the 1.2 g/kg Cabbage needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
