Growing Tea in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Quick answer

Generally not ideal — Samburu is poorly suited to Tea. Samburu's soil (pH 8.28, alkaline) gives Tea a suitability score of 2/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.

Samburu County is a challenging environment for Tea (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Tea's preferred 4.5–6 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Tea prefers clay soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Tea's minimum of 1100 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Tea is the #103 soil match of the 106 crops we assess for Samburu County. Tea's full potential is about 2,200 kg/acre (~KES 55,000/acre at KES 25/kg), but at Samburu's 2/100 suitability a realistic target here is closer to 55 kg/acre (~KES 1,375/acre) unless the constraints above are addressed.

Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Samburu's nitrogen (0.67 g/kg) is 56% of the 1.2 g/kg Tea needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
