Growing Jute Mallow (Mrenda) in Isiolo
Soil suitability analysis based on Isiolo's nutrient profile
Generally not ideal — Isiolo is poorly suited to Jute Mallow (Mrenda). Isiolo's soil (pH 7.83, alkaline) gives Jute Mallow (Mrenda) a suitability score of 19/100. Match fertilizer to Isiolo's nitrogen and phosphorus levels for the best result.
Isiolo County is a challenging environment for Jute Mallow (Mrenda) (soil-match score 19/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 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 Isiolo is largely sandy, so drainage and organic-matter management matter more here. Isiolo receives approximately 350 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 #58 soil match of the 106 crops we assess for Isiolo County. Jute Mallow (Mrenda)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Isiolo's 19/100 suitability a realistic target here is closer to 1,188 kg/acre (~KES 59,400/acre) unless the constraints above are addressed.
Better matched to Isiolo's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Isiolo's nitrogen (0.46 g/kg) is 38% of the 1.2 g/kg Jute Mallow (Mrenda) needs, so the standard 0.3 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
