Growing Garden Peas in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a challenging environment for Garden Peas (soil-match score 41/100) and will need significant amendment before planting. At an average pH of 4.99 the soil is strongly acidic, below Garden Peas's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Garden Peas's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Garden Peas, which favours sandy loam. On ShambaIQ's soil-match model, Garden Peas is the #77 soil match of the 106 crops we assess for Laikipia County. Garden Peas's full potential is about 2,500 kg/acre (~KES 362,500/acre at KES 145/kg), but at Laikipia's 41/100 suitability a realistic target here is closer to 1,281 kg/acre (~KES 185,745/acre) unless the constraints above are addressed.

Better matched to Laikipia's soil: Sweet Potato, Finger Millet, and Groundnuts — each scores higher on the same soil.
