Growing Cape Gooseberry in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Quick answer

Generally not ideal — Garissa is poorly suited to Cape Gooseberry. Garissa's soil (pH 7.96, alkaline) gives Cape Gooseberry 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 Cape Gooseberry (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Cape Gooseberry's preferred 6–7.5 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 medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Cape Gooseberry prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Cape Gooseberry's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Cape Gooseberry is the #105 soil match of the 106 crops we assess for Garissa County. Cape Gooseberry's full potential is about 5,000 kg/acre (~KES 600,000/acre at KES 120/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.
