Growing Spider Plant (Saga) in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Nyamira County is a solid choice for Spider Plant (Saga), with a soil-match score of 70/100. At an average pH of 5.58 the soil is slightly acidic to near-neutral, below Spider Plant (Saga)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Spider Plant (Saga), which favours loam. Spider Plant (Saga)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Nyamira's 70/100 suitability a realistic target here is closer to 4,375 kg/acre (~KES 218,750/acre) unless the constraints above are addressed.
