Growing Rice (Upland) in Kajiado

Soil suitability analysis based on Kajiado's nutrient profile

Kajiado County is a challenging environment for Rice (Upland) (soil-match score 33/100) and will need significant amendment before planting. Local soils average pH 6.55 — neutral and inside the 5–7 band Rice (Upland) prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.97 g/kg, P 20.6 mg/kg, K 257 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 Kajiado is largely sandy loam, so drainage and organic-matter management matter more here. Kajiado receives approximately 500 mm/year — well below Rice (Upland)'s minimum of 800 mm — so supplemental irrigation would be essential for this crop. Rice (Upland)'s full potential is about 1,800 kg/acre (~KES 189,000/acre at KES 105/kg), but at Kajiado's 33/100 suitability a realistic target here is closer to 743 kg/acre (~KES 78,015/acre) unless the constraints above are addressed.
