Growing Coconuts in Meru

Soil suitability analysis based on Meru's nutrient profile

Meru County is a challenging environment for Coconuts (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Coconuts's preferred 5.5–8 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Coconuts's requirements, so a maintenance fertilizer programme is enough. Coconuts prefers sandy soils, while Meru is largely clay loam, so drainage and organic-matter management matter more here. At 1500 m, the county sits above Coconuts's preferred altitude ceiling of 400 m, where frost risk and cold nights reduce the crop's productivity. Coconuts's full potential is about 2,500 kg/acre (~KES 55,000/acre at KES 22/kg), but at Meru's 4/100 suitability a realistic target here is closer to 125 kg/acre (~KES 2,750/acre) unless the constraints above are addressed.
