Growing Tea in Siaya
Soil suitability analysis based on Siaya's nutrient profile
Yes, with the right inputs — Siaya is moderately suited to Tea. Siaya's soil (pH 5.33, strongly acidic) gives Tea a suitability score of 57/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Tea can be grown in Siaya County, but the soil scores 57/100 and needs targeted management to reach full potential. Local soils average pH 5.33 — moderately acidic and inside the 4.5–6 band Tea prefers, so no lime is usually required. The main gap is potassium — measured at N 1.2 g/kg, P 12.1 mg/kg, K 134 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Tea, which favours clay. On ShambaIQ's soil-match model, Tea is the #72 soil match of the 106 crops we assess for Siaya County. Tea's full potential is about 2,200 kg/acre (~KES 55,000/acre at KES 25/kg), but at Siaya's 57/100 suitability a realistic target here is closer to 1,568 kg/acre (~KES 39,200/acre) unless the constraints above are addressed.
Better matched to Siaya's soil: Macadamia, Pineapple, and Avocado — each scores higher on the same soil.
