Growing Vine Spinach (Nderema) in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Yes, with the right inputs — Kisii is moderately suited to Vine Spinach (Nderema). Kisii's soil (pH 5.21, strongly acidic) gives Vine Spinach (Nderema) a suitability score of 71/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kisii County is a solid choice for Vine Spinach (Nderema), with a soil-match score of 71/100. At an average pH of 5.21 the soil is moderately acidic, 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 — measured at N 1.09 g/kg, P 13.1 mg/kg, K 151 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Vine Spinach (Nderema), which favours loam. On ShambaIQ's soil-match model, Vine Spinach (Nderema) is the #22 soil match of the 106 crops we assess for Kisii County. Vine Spinach (Nderema)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Kisii's 71/100 suitability a realistic target here is closer to 4,438 kg/acre (~KES 221,900/acre) unless the constraints above are addressed.
