Growing Garden Peas in Garissa

Soil suitability analysis based on Garissa's nutrient profile

Garissa County is a challenging environment for Garden Peas (soil-match score 0/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Garden Peas's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.61 g/kg), phosphorus (37.7 mg/kg) and potassium (407 mg/kg) all meet Garden Peas's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Garden Peas, which favours sandy loam. Garissa receives approximately 250 mm/year — well below Garden Peas's minimum of 800 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Garden Peas is the #98 soil match of the 106 crops we assess for Garissa County. Garden Peas's full potential is about 2,500 kg/acre (~KES 362,500/acre at KES 145/kg), but at Garissa'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 Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
