Growing Sweet Orange in Nyeri
Soil suitability analysis based on Nyeri's nutrient profile
Yes, with the right inputs — Nyeri is moderately suited to Sweet Orange. Nyeri's soil (pH 5.23, strongly acidic) gives Sweet Orange a suitability score of 61/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Nyeri County is a solid choice for Sweet Orange, with a soil-match score of 61/100. At an average pH of 5.23 the soil is moderately acidic, below Sweet Orange'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 1.09 g/kg, P 15.5 mg/kg, K 192 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Sweet Orange prefers loam soils, while Nyeri is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sweet Orange is the #63 soil match of the 106 crops we assess for Nyeri County. Sweet Orange's full potential is about 12,000 kg/acre (~KES 600,000/acre at KES 50/kg), but at Nyeri's 61/100 suitability a realistic target here is closer to 9,150 kg/acre (~KES 457,500/acre) unless the constraints above are addressed.

Top dressing guide
Nyeri's nitrogen (1.09 g/kg) is 91% of the 1.2 g/kg Sweet Orange needs, so the standard 0.6 bags/acre is raised to 0.75. Split it across two applications to limit leaching.
