Growing Lucerne in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Possible but challenging — Turkana is only marginally suited to Lucerne. Turkana's soil (pH 7.95, alkaline) gives Lucerne a suitability score of 43/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Lucerne (soil-match score 43/100) and will need significant amendment before planting. Local soils average pH 7.95 — alkaline and inside the 6.5–8 band Lucerne prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Lucerne prefers clay loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lucerne is the #10 soil match of the 106 crops we assess for Turkana County. Lucerne's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Turkana's 43/100 suitability a realistic target here is closer to 4,300 kg/acre (~KES 120,400/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen reads 0.41 g/kg, but the rate stays at zero: Lucerne is not top-dressed, for the crop-specific reason above.
