Soil suitability analysis based on Taita Taveta's nutrient profile
Possible but challenging — Taita Taveta is only marginally suited to Dolichos. Taita Taveta's soil (pH 6.64, near-neutral) gives Dolichos a suitability score of 44/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.
Taita Taveta County is a challenging environment for Dolichos (soil-match score 44/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (0.97 g/kg), phosphorus (12.9 mg/kg) and potassium (104 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. The county's predominantly loam soils suit Dolichos, which favours sandy loam. On ShambaIQ's soil-match model, Dolichos is the #58 soil match of the 106 crops we assess for Taita Taveta County. Dolichos's full potential is about 600 kg/acre (~KES 72,000/acre at KES 120/kg), but at Taita Taveta's 44/100 suitability a realistic target here is closer to 330 kg/acre (~KES 39,600/acre) unless the constraints above are addressed.
Better matched to Taita Taveta's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.
