Growing Lemon in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Quick answer

Possible but challenging — Nyandarua is only marginally suited to Lemon. Nyandarua's soil (pH 5.38, strongly acidic) gives Lemon a suitability score of 53/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Lemon can be grown in Nyandarua County, but the soil scores 53/100 and needs targeted management to reach full potential. At an average pH of 5.38 the soil is moderately acidic, below Lemon's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Lemon prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lemon is the #63 soil match of the 106 crops we assess for Nyandarua County. Lemon's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Nyandarua's 53/100 suitability a realistic target here is closer to 6,625 kg/acre (~KES 331,250/acre) unless the constraints above are addressed.

Better matched to Nyandarua's soil: Tea, Pyrethrum, and Potato — each scores higher on the same soil.
