Growing Spinach in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Kisii County is a solid choice for Spinach, with a soil-match score of 62/100. At an average pH of 5.21 the soil is moderately acidic, below Spinach's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Spinach, which favours loam. At current prices (about KES 25/kg) and a typical 3,500 kg/acre yield, a well-managed Spinach crop here can gross roughly KES 87,500 per acre.
