Growing Tomato in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Quick answer

Yes, with the right inputs — Laikipia is moderately suited to Tomato. Laikipia's soil (pH 4.99, strongly acidic) gives Tomato a suitability score of 64/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Laikipia County is a solid choice for Tomato, with a soil-match score of 64/100. At an average pH of 4.99 the soil is strongly acidic, below Tomato's preferred 6–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.42 g/kg, P 16.6 mg/kg, K 215 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 Tomato, which favours loam. On ShambaIQ's soil-match model, Tomato is the #35 soil match of the 106 crops we assess for Laikipia County. Tomato's full potential is about 15,000 kg/acre (~KES 750,000/acre at KES 50/kg), but at Laikipia's 64/100 suitability a realistic target here is closer to 12,000 kg/acre (~KES 600,000/acre) unless the constraints above are addressed.
