Growing Amaranth in Kisumu

Soil suitability analysis based on Kisumu's nutrient profile

Quick answer

Yes, with the right inputs — Kisumu is moderately suited to Amaranth. Kisumu's soil (pH 5.54, slightly acidic) gives Amaranth a suitability score of 74/100. Match fertilizer to Kisumu's nitrogen and phosphorus levels for the best result.

Kisumu County is a solid choice for Amaranth, with a soil-match score of 74/100. Local soils average pH 5.54 — slightly acidic to near-neutral and inside the 5.5–7.5 band Amaranth prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.91 g/kg, P 12.5 mg/kg, K 166 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Amaranth prefers loam soils, while Kisumu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Amaranth is the #34 soil match of the 106 crops we assess for Kisumu County. At current prices (about KES 40/kg) and a typical 5,000 kg/acre yield, a well-managed Amaranth crop here can gross roughly KES 200,000 per acre.
