Growing Lemongrass in Kajiado
Soil suitability analysis based on Kajiado's nutrient profile
Possible but challenging — Kajiado is only marginally suited to Lemongrass. Kajiado's soil (pH 6.55, near-neutral) gives Lemongrass a suitability score of 47/100. Match fertilizer to Kajiado's nitrogen and phosphorus levels for the best result.
Lemongrass can be grown in Kajiado County, but the soil scores 47/100 and needs targeted management to reach full potential. Local soils average pH 6.55 — neutral and inside the 5.5–7.5 band Lemongrass prefers, so no lime is usually required. Nitrogen (0.97 g/kg), phosphorus (20.6 mg/kg) and potassium (257 mg/kg) all meet Lemongrass's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Lemongrass, which favours loam. Kajiado receives approximately 500 mm/year — well below Lemongrass's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Lemongrass is the #65 soil match of the 106 crops we assess for Kajiado County. Lemongrass's full potential is about 8,000 kg/acre (~KES 480,000/acre at KES 60/kg), but at Kajiado's 47/100 suitability a realistic target here is closer to 4,700 kg/acre (~KES 282,000/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.
