Growing Strawberry in Machakos

Soil suitability analysis based on Machakos's nutrient profile

Machakos County is a challenging environment for Strawberry (soil-match score 40/100) and will need significant amendment before planting. At an average pH of 7.03 the soil sits above Strawberry's preferred 5.5–6.8 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.82 g/kg, P 31.4 mg/kg, K 338 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 Machakos's 40/100 suitability a realistic target here is closer to 3,000 kg/acre (~KES 600,000/acre) unless the constraints above are addressed.
