Growing Jute Mallow (Mrenda) in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Jute Mallow (Mrenda). Garissa's soil (pH 7.96, alkaline) gives Jute Mallow (Mrenda) a suitability score of 10/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Jute Mallow (Mrenda) (soil-match score 10/100) and will need significant amendment before planting. At an average pH of 7.96 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 0.61 g/kg, P 37.7 mg/kg, K 407 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 Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 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 #48 soil match of the 106 crops we assess for Garissa County. Jute Mallow (Mrenda)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Garissa's 10/100 suitability a realistic target here is closer to 625 kg/acre (~KES 31,250/acre) unless the constraints above are addressed.
Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
