Growing Eggplant in Tharaka Nithi

Soil suitability analysis based on Tharaka Nithi's nutrient profile

Tharaka Nithi County is a solid choice for Eggplant, with a soil-match score of 70/100. At an average pH of 4.99 the soil is strongly acidic, below Eggplant's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.23 g/kg, P 19.6 mg/kg, K 211 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Eggplant, which favours loam. At current prices (about KES 50/kg) and a typical 8,000 kg/acre yield, a well-managed Eggplant crop here can gross roughly KES 400,000 per acre.
