Growing Beetroot in Kirinyaga
Soil suitability analysis based on Kirinyaga's nutrient profile
Beetroot can be grown in Kirinyaga County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.31 the soil is moderately acidic, below Beetroot's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.36 g/kg, P 12.5 mg/kg, K 177 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Beetroot prefers loam soils, while Kirinyaga is largely clay, so drainage and organic-matter management matter more here. Beetroot's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Kirinyaga's 59/100 suitability a realistic target here is closer to 7,375 kg/acre (~KES 368,750/acre) unless the constraints above are addressed.
