Growing Jute Mallow (Mrenda) in Mandera
Soil suitability analysis based on Mandera's nutrient profile
Generally not ideal — Mandera is poorly suited to Jute Mallow (Mrenda). Mandera's soil (pH 8.38, alkaline) gives Jute Mallow (Mrenda) a suitability score of 4/100. Match fertilizer to Mandera's nitrogen and phosphorus levels for the best result.
Mandera County is a challenging environment for Jute Mallow (Mrenda) (soil-match score 4/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Jute Mallow (Mrenda)'s preferred 5.8–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.53 g/kg, P 38.3 mg/kg, K 420 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Jute Mallow (Mrenda) prefers loam soils, while Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 mm/year — well below Jute Mallow (Mrenda)'s minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Jute Mallow (Mrenda) is the #45 soil match of the 106 crops we assess for Mandera County. Jute Mallow (Mrenda)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Mandera's 4/100 suitability a realistic target here is closer to 250 kg/acre (~KES 12,500/acre) unless the constraints above are addressed.
Better matched to Mandera's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
