Growing Vine Spinach (Nderema) in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Nyamira County is well suited to Vine Spinach (Nderema), scoring 76/100 on ShambaIQ's soil-match model. At an average pH of 5.58 the soil is slightly acidic to near-neutral, below Vine Spinach (Nderema)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Vine Spinach (Nderema), which favours loam. At current prices (about KES 50/kg) and a typical 5,000 kg/acre yield, a well-managed Vine Spinach (Nderema) crop here can gross roughly KES 250,000 per acre.
