Growing Pineapple in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Quick answer

Yes, with the right inputs — Nyandarua is moderately suited to Pineapple. Nyandarua's soil (pH 5.38, strongly acidic) gives Pineapple a suitability score of 56/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Pineapple can be grown in Nyandarua County, but the soil scores 56/100 and needs targeted management to reach full potential. Local soils average pH 5.38 — moderately acidic and inside the 4.5–6.5 band Pineapple prefers, so no lime is usually required. The main gap is potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's medium/low/high demand — so the fertilizer plan below prioritises closing that deficit. Pineapple prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 m, the county sits above Pineapple's preferred altitude ceiling of 1800 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Pineapple is the #58 soil match of the 106 crops we assess for Nyandarua County. Pineapple's full potential is about 25,000 kg/acre (~KES 875,000/acre at KES 35/kg), but at Nyandarua's 56/100 suitability a realistic target here is closer to 17,500 kg/acre (~KES 612,500/acre) unless the constraints above are addressed.

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