Growing Mint in Kajiado
Soil suitability analysis based on Kajiado's nutrient profile
Possible but challenging — Kajiado is only marginally suited to Mint. Kajiado's soil (pH 6.55, near-neutral) gives Mint a suitability score of 46/100. Match fertilizer to Kajiado's nitrogen and phosphorus levels for the best result.
Mint can be grown in Kajiado County, but the soil scores 46/100 and needs targeted management to reach full potential. Local soils average pH 6.55 — neutral and inside the 6–7.5 band Mint prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.97 g/kg, P 20.6 mg/kg, K 257 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Mint, which favours loam. Kajiado receives approximately 500 mm/year — well below Mint's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Mint is the #69 soil match of the 106 crops we assess for Kajiado County. Mint's full potential is about 4,000 kg/acre (~KES 400,000/acre at KES 100/kg), but at Kajiado's 46/100 suitability a realistic target here is closer to 2,300 kg/acre (~KES 230,000/acre) unless the constraints above are addressed.
Better matched to Kajiado's soil: Sorghum, Cowpeas, and Pigeon Peas — each scores higher on the same soil.

Top dressing guide
Kajiado's nitrogen (0.97 g/kg) is 81% of the 1.2 g/kg Mint needs, so the standard 0.3 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
