Growing Radish in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Radish (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Radish's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 39.3 mg/kg, K 396 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Radish, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Radish's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Radish is the #60 soil match of the 106 crops we assess for Wajir County. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Wajir's 2/100 suitability a realistic target here is closer to 200 kg/acre (~KES 8,000/acre) unless the constraints above are addressed.

Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
