Soil suitability analysis based on Siaya's nutrient profile

Siaya County is well suited to Macadamia, scoring 91/100 on ShambaIQ's soil-match model. Local soils average pH 5.33 — moderately acidic and inside the 4.5–6.5 band Macadamia 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 medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Macadamia, which favours loam. On ShambaIQ's soil-match model, Macadamia is the single best-matched crop of the 106 we assess for Siaya County. At current prices (about KES 110/kg) and a typical 1,800 kg/acre yield, a well-managed Macadamia crop here can gross roughly KES 198,000 per acre.
