Growing Maize in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Quick answer

Generally not ideal — Marsabit is poorly suited to Maize. Marsabit's soil (pH 8.22, alkaline) gives Maize a suitability score of 17/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.

Marsabit County is a challenging environment for Maize (soil-match score 17/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Maize's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. 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 high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. Maize prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Maize's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Maize is the #44 soil match of the 106 crops we assess for Marsabit County. Maize's full potential is about 1,800 kg/acre (~KES 81,000/acre at KES 45/kg), but at Marsabit's 17/100 suitability a realistic target here is closer to 383 kg/acre (~KES 17,235/acre) unless the constraints above are addressed.

Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.

Marsabit's nitrogen (0.52 g/kg) is 43% of the 1.2 g/kg Maize needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
