Growing Amaranth in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Amaranth (soil-match score 25/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Amaranth's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.67 g/kg, P 42.1 mg/kg, K 387 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Amaranth prefers loam soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Amaranth's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Amaranth is the #36 soil match of the 106 crops we assess for Samburu County. Amaranth's full potential is about 5,000 kg/acre (~KES 200,000/acre at KES 40/kg), but at Samburu's 25/100 suitability a realistic target here is closer to 1,563 kg/acre (~KES 62,520/acre) unless the constraints above are addressed.

Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
