Quick answer

Yes, with the right inputs — Murang'a is moderately suited to Garden Peas. Murang'a's soil (pH 5.03, strongly acidic) gives Garden Peas a suitability score of 73/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Murang'a County is a solid choice for Garden Peas, with a soil-match score of 73/100. At an average pH of 5.03 the soil is moderately acidic, below Garden Peas's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Garden Peas's requirements, so a maintenance fertilizer programme is enough. Garden Peas prefers sandy loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Garden Peas is the #19 soil match of the 106 crops we assess for Murang'a County. At current prices (about KES 145/kg) and a typical 2,500 kg/acre yield, a well-managed Garden Peas crop here can gross roughly KES 362,500 per acre.
