Growing Vine Spinach (Nderema) in Makueni
Soil suitability analysis based on Makueni's nutrient profile
Generally not ideal — Makueni is poorly suited to Vine Spinach (Nderema). Makueni's soil (pH 7.5, alkaline) gives Vine Spinach (Nderema) a suitability score of 39/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.
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. On ShambaIQ's soil-match model, Vine Spinach (Nderema) is the #75 soil match of the 106 crops we assess for Makueni County. 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.
Better matched to Makueni's soil: Lucerne, Mango, and Sisal — each scores higher on the same soil.
