Growing Leek in Nyeri

Soil suitability analysis based on Nyeri's nutrient profile

Nyeri County is a solid choice for Leek, with a soil-match score of 65/100. At an average pH of 5.23 the soil is moderately acidic, below Leek's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen and potassium — measured at N 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing those deficits. Leek prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Nyeri's 65/100 suitability a realistic target here is closer to 8,125 kg/acre (~KES 487,500/acre) unless the constraints above are addressed.
