Soil suitability analysis based on West Pokot's nutrient profile

Quick answer

West Pokot County is well suited to Dolichos, scoring 93/100 on ShambaIQ's soil-match model. Local soils average pH 6.04 — slightly acidic to near-neutral and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (1.67 g/kg), phosphorus (24.8 mg/kg) and potassium (211 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Dolichos, which favours sandy loam. On ShambaIQ's soil-match model, Dolichos is the #9 soil match of the 106 crops we assess for West Pokot County. At current prices (about KES 120/kg) and a typical 600 kg/acre yield, a well-managed Dolichos crop here can gross roughly KES 72,000 per acre.

Dolichos (njahi) fixes its own nitrogen through rhizobia. Do NOT apply CAN — it suppresses nodulation and reduces yield. A starter dose of phosphorus at planting is enough.
