Growing Amaranth in Embu
Soil suitability analysis based on Embu's nutrient profile
Yes, with the right inputs — Embu is moderately suited to Amaranth. Embu's soil (pH 5.1, strongly acidic) gives Amaranth a suitability score of 67/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Embu County is a solid choice for Amaranth, with a soil-match score of 67/100. At an average pH of 5.1 the soil is moderately acidic, below Amaranth's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is nitrogen — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 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 Amaranth, which favours loam. On ShambaIQ's soil-match model, Amaranth is the #32 soil match of the 106 crops we assess for Embu County. Amaranth's full potential is about 5,000 kg/acre (~KES 200,000/acre at KES 40/kg), but at Embu's 67/100 suitability a realistic target here is closer to 4,188 kg/acre (~KES 167,520/acre) unless the constraints above are addressed.
