Growing Strawberry in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Quick answer

Generally not ideal — Makueni is poorly suited to Strawberry. Makueni's soil (pH 7.5, alkaline) gives Strawberry a suitability score of 21/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.

Makueni County is a challenging environment for Strawberry (soil-match score 21/100) and will need significant amendment before planting. At an average pH of 7.5 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 0.86 g/kg, P 29.6 mg/kg, K 351 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. At 1000 m, the county sits below Strawberry's preferred altitude range (1500–2800 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Strawberry is the #89 soil match of the 106 crops we assess for Makueni County. Strawberry's full potential is about 6,000 kg/acre (~KES 1,200,000/acre at KES 200/kg), but at Makueni's 21/100 suitability a realistic target here is closer to 1,575 kg/acre (~KES 315,000/acre) unless the constraints above are addressed.

Better matched to Makueni's soil: Lucerne, Mango, and Sisal — each scores higher on the same soil.
