Growing Rice (Lowland/Paddy) in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Rice (Lowland/Paddy) (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Rice (Lowland/Paddy)'s preferred 4.5–7 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 (Lowland/Paddy) 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 (Lowland/Paddy)'s minimum of 1100 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 100/kg) and a typical 2,000 kg/acre yield, a well-managed Rice (Lowland/Paddy) crop here can gross roughly KES 200,000 per acre.
