Growing Quinoa in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Quinoa (soil-match score 38/100) and will need significant amendment before planting. Local soils average pH 8.22 — alkaline and inside the 6–8.5 band Quinoa prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.52 g/kg, P 37.3 mg/kg, K 420 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Quinoa prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Quinoa's full potential is about 700 kg/acre (~KES 105,000/acre at KES 150/kg), but at Marsabit's 38/100 suitability a realistic target here is closer to 333 kg/acre (~KES 49,950/acre) unless the constraints above are addressed.
