Growing Radish in Kirinyaga
Soil suitability analysis based on Kirinyaga's nutrient profile
Yes, with the right inputs — Kirinyaga is moderately suited to Radish. Kirinyaga's soil (pH 5.31, strongly acidic) gives Radish a suitability score of 58/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Radish can be grown in Kirinyaga County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.31 the soil is moderately acidic, below Radish's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.36 g/kg), phosphorus (12.5 mg/kg) and potassium (177 mg/kg) all meet Radish's requirements, so a maintenance fertilizer programme is enough. Radish prefers sandy loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Radish is the #73 soil match of the 106 crops we assess for Kirinyaga County. Radish's full potential is about 8,000 kg/acre (~KES 320,000/acre at KES 40/kg), but at Kirinyaga's 58/100 suitability a realistic target here is closer to 5,800 kg/acre (~KES 232,000/acre) unless the constraints above are addressed.
Better matched to Kirinyaga's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
