Growing Leek in Siaya

Soil suitability analysis based on Siaya's nutrient profile

Siaya County is a solid choice for Leek, with a soil-match score of 64/100. At an average pH of 5.33 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 potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Leek, which favours loam. Leek's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Siaya's 64/100 suitability a realistic target here is closer to 8,000 kg/acre (~KES 480,000/acre) unless the constraints above are addressed.
