Growing Spinach in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Quick answer

Yes — Trans Nzoia is well suited to Spinach. Trans Nzoia's soil (pH 5.93, slightly acidic) gives Spinach a suitability score of 83/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.

Trans Nzoia County is well suited to Spinach, scoring 83/100 on ShambaIQ's soil-match model. At an average pH of 5.93 the soil is slightly acidic to near-neutral, below Spinach's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Spinach's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Spinach, which favours loam. At current prices (about KES 25/kg) and a typical 8,000 kg/acre yield, a well-managed Spinach crop here can gross roughly KES 200,000 per acre.
