Growing Sorghum in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Sorghum, with a soil-match score of 68/100. At an average pH of 4.99 the soil is strongly acidic, below Sorghum's preferred 5–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Sorghum's requirements, so a maintenance fertilizer programme is enough. Sorghum prefers clay soils, while Laikipia is largely sandy loam, so drainage and organic-matter management matter more here. Sorghum's full potential is about 1,200 kg/acre (~KES 81,600/acre at KES 68/kg), but at Laikipia's 68/100 suitability a realistic target here is closer to 1,020 kg/acre (~KES 69,360/acre) unless the constraints above are addressed.
