Growing Vine Spinach (Nderema) in Makueni

Soil suitability analysis based on Makueni's nutrient profile

Makueni County is a challenging environment for Vine Spinach (Nderema) (soil-match score 39/100) and will need significant amendment before planting. At an average pH of 7.5 the soil sits above Vine Spinach (Nderema)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.86 g/kg, P 29.6 mg/kg, K 351 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Vine Spinach (Nderema), which favours loam. Vine Spinach (Nderema)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Makueni's 39/100 suitability a realistic target here is closer to 2,438 kg/acre (~KES 121,900/acre) unless the constraints above are addressed.
