Machakos County is a solid choice for Vine Spinach (Nderema), with a soil-match score of 61/100. At an average pH of 7.03 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 0.82 g/kg, P 31.4 mg/kg, K 338 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 Machakos County.
