Growing Spider Plant (Saga) in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Spider Plant (Saga). Turkana's soil (pH 7.95, alkaline) gives Spider Plant (Saga) a suitability score of 12/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Spider Plant (Saga) (soil-match score 12/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Spider Plant (Saga)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Spider Plant (Saga) prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Spider Plant (Saga)'s minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Spider Plant (Saga) is the #49 soil match of the 106 crops we assess for Turkana County. Spider Plant (Saga)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Turkana's 12/100 suitability a realistic target here is closer to 750 kg/acre (~KES 37,500/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
