Growing Garlic in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is a solid choice for Garlic, with a soil-match score of 60/100. At an average pH of 5.38 the soil is moderately acidic, below Garlic's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Garlic prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 275/kg) and a typical 1,800 kg/acre yield, a well-managed Garlic crop here can gross roughly KES 495,000 per acre.
