Growing Butternut Squash in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Butternut Squash (soil-match score 27/100) and will need significant amendment before planting. At an average pH of 8.28 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 0.67 g/kg, P 42.1 mg/kg, K 387 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. Samburu receives approximately 350 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 #30 soil match of the 106 crops we assess for Samburu County. Butternut Squash's full potential is about 10,000 kg/acre (~KES 400,000/acre at KES 40/kg), but at Samburu's 27/100 suitability a realistic target here is closer to 3,375 kg/acre (~KES 135,000/acre) unless the constraints above are addressed.

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