Growing Lucerne in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

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. At current prices (about KES 28/kg) and a typical 6,500 kg/acre yield, a well-managed Lucerne crop here can gross roughly KES 182,000 per acre.
