Growing Strawberry in Kwale

Soil suitability analysis based on Kwale's nutrient profile

Quick answer

Generally not ideal — Kwale is poorly suited to Strawberry. Kwale's soil (pH 6.76, near-neutral) gives Strawberry a suitability score of 1/100. Match fertilizer to Kwale's nitrogen and phosphorus levels for the best result.

Kwale County is a challenging environment for Strawberry (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.76 — neutral and inside the 5.5–6.8 band Strawberry prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.93 g/kg, P 9.8 mg/kg, K 131 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Strawberry, which favours loam. At 200 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 #105 soil match of the 106 crops we assess for Kwale County. Strawberry's full potential is about 6,000 kg/acre (~KES 1,200,000/acre at KES 200/kg), but at Kwale's 1/100 suitability a realistic target here is closer to 75 kg/acre (~KES 15,000/acre) unless the constraints above are addressed.

Better matched to Kwale's soil: Dhania, Pigeon Peas, and Mango — each scores higher on the same soil.

Bags per acre in Kwale
0.50.4

Kwale's nitrogen (0.93 g/kg) is 78% of the 1.2 g/kg Strawberry needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
