Growing Rice (Lowland/Paddy) in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Quick answer

Yes, with the right inputs — Mombasa is moderately suited to Rice (Lowland/Paddy). Mombasa's soil (pH 6.24, slightly acidic) gives Rice (Lowland/Paddy) a suitability score of 66/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.

Mombasa County is a solid choice for Rice (Lowland/Paddy), with a soil-match score of 66/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 4.5–7 band Rice (Lowland/Paddy) prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.95 g/kg, P 8.4 mg/kg, K 136 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. Rice (Lowland/Paddy) prefers clay soils, while Mombasa is largely sandy, so drainage and organic-matter management matter more here. Rice (Lowland/Paddy)'s full potential is about 2,600 kg/acre (~KES 260,000/acre at KES 100/kg), but at Mombasa's 66/100 suitability a realistic target here is closer to 2,145 kg/acre (~KES 214,500/acre) unless the constraints above are addressed.
