Growing Lemon in Embu
Soil suitability analysis based on Embu's nutrient profile
Yes, with the right inputs — Embu is moderately suited to Lemon. Embu's soil (pH 5.1, strongly acidic) gives Lemon a suitability score of 56/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Lemon can be grown in Embu County, but the soil scores 56/100 and needs targeted management to reach full potential. At an average pH of 5.1 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 nitrogen, phosphorus, and potassium — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Lemon, which favours loam. On ShambaIQ's soil-match model, Lemon is the #65 soil match of the 106 crops we assess for Embu County. Lemon's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Embu's 56/100 suitability a realistic target here is closer to 7,000 kg/acre (~KES 350,000/acre) unless the constraints above are addressed.
Better matched to Embu's soil: Pineapple, Avocado, and Macadamia — each scores higher on the same soil.

Top dressing guide
Embu's nitrogen (1.04 g/kg) is 87% of the 1.2 g/kg Lemon needs, so the standard 0.6 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
