Growing Rice (Upland) in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Rice (Upland) (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Rice (Upland)'s preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Rice (Upland) prefers clay soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Rice (Upland)'s minimum of 800 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Rice (Upland) is the #53 soil match of the 106 crops we assess for Mandera County. Rice (Upland)'s full potential is about 1,800 kg/acre (~KES 189,000/acre at KES 105/kg), but at Mandera's 2/100 suitability a realistic target here is closer to 45 kg/acre (~KES 4,725/acre) unless the constraints above are addressed.

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