Soil suitability analysis based on Narok's nutrient profile

Quick answer

Yes — Narok is well suited to Dolichos. Narok's soil (pH 6.13, slightly acidic) gives Dolichos a suitability score of 94/100. Match fertilizer to Narok's nitrogen and phosphorus levels for the best result.

Narok County is well suited to Dolichos, scoring 94/100 on ShambaIQ's soil-match model. Local soils average pH 6.13 — slightly acidic to near-neutral and inside the 5–7.5 band Dolichos prefers, so no lime is usually required. Nitrogen (1.63 g/kg), phosphorus (25.7 mg/kg) and potassium (234 mg/kg) all meet Dolichos's requirements, so a maintenance fertilizer programme is enough. Dolichos prefers sandy loam soils, while Narok is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Dolichos is the #4 soil match of the 106 crops we assess for Narok 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.

Instruction

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.
