Growing Lucerne in Isiolo
Soil suitability analysis based on Isiolo's nutrient profile
Yes, with the right inputs — Isiolo is moderately suited to Lucerne. Isiolo's soil (pH 7.83, alkaline) gives Lucerne a suitability score of 64/100. Match fertilizer to Isiolo's nitrogen and phosphorus levels for the best result.
Isiolo County is a solid choice for Lucerne, with a soil-match score of 64/100. Local soils average pH 7.83 — alkaline and inside the 6.5–8 band Lucerne prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.46 g/kg, P 37.4 mg/kg, K 395 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 Isiolo is largely sandy, so drainage and organic-matter management matter more here. Lucerne's full potential is about 8,000 kg/acre (~KES 224,000/acre at KES 28/kg), but at Isiolo's 64/100 suitability a realistic target here is closer to 6,400 kg/acre (~KES 179,200/acre) unless the constraints above are addressed.
