Growing Coconuts in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Quick answer

Generally not ideal — Makueni is poorly suited to Coconuts. Makueni's soil (pH 7.5, alkaline) gives Coconuts a suitability score of 11/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.

Makueni County is a challenging environment for Coconuts (soil-match score 11/100) and will need significant amendment before planting. Local soils average pH 7.5 — alkaline and inside the 5.5–8 band Coconuts prefers, so no lime is usually required. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Coconuts's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Coconuts, which favours sandy. At 1000 m, the county sits above Coconuts's preferred altitude ceiling of 400 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Coconuts is the #101 soil match of the 106 crops we assess for Makueni County. Coconuts's full potential is about 2,500 kg/acre (~KES 55,000/acre at KES 22/kg), but at Makueni's 11/100 suitability a realistic target here is closer to 344 kg/acre (~KES 7,568/acre) unless the constraints above are addressed.

Better matched to Makueni's soil: Lucerne, Mango, and Sisal — each scores higher on the same soil.
