Growing Butternut Squash in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Butternut Squash (soil-match score 8/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Butternut Squash's preferred 5.5–7.5 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/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Butternut Squash, which favours sandy loam. Wajir receives approximately 200 mm/year — well below Butternut Squash's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Butternut Squash is the #25 soil match of the 106 crops we assess for Wajir County. Butternut Squash's full potential is about 10,000 kg/acre (~KES 400,000/acre at KES 40/kg), but at Wajir's 8/100 suitability a realistic target here is closer to 1,000 kg/acre (~KES 40,000/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.
