Growing Snow Peas in Mandera
Soil suitability analysis based on Mandera's nutrient profile
Generally not ideal — Mandera is poorly suited to Snow Peas. Mandera's soil (pH 8.38, alkaline) gives Snow Peas a suitability score of 0/100. Match fertilizer to Mandera's nitrogen and phosphorus levels for the best result.
Mandera County is a challenging environment for Snow Peas (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Snow Peas's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 mg/kg) all meet Snow Peas's requirements, so a maintenance fertilizer programme is enough. Snow Peas prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Snow Peas's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Snow Peas is the #86 soil match of the 106 crops we assess for Mandera County. Snow Peas's full potential is about 1,800 kg/acre (~KES 333,000/acre at KES 185/kg), but at Mandera'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 Mandera's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Mandera's nitrogen reads 0.53 g/kg, but the rate stays at zero: Snow Peas is not top-dressed, for the crop-specific reason above.
