Growing Strawberry in Tharaka Nithi

Soil suitability analysis based on Tharaka Nithi's nutrient profile

Tharaka Nithi County is a challenging environment for Strawberry (soil-match score 39/100) and will need significant amendment before planting. At an average pH of 4.99 the soil is strongly acidic, below Strawberry's preferred 5.5–6.8 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 Strawberry, which favours loam. Strawberry's full potential is about 6,000 kg/acre (~KES 1,200,000/acre at KES 200/kg), but at Tharaka Nithi's 39/100 suitability a realistic target here is closer to 2,925 kg/acre (~KES 585,000/acre) unless the constraints above are addressed.
