Growing Jute Mallow (Mrenda) in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Jute Mallow (Mrenda) can be grown in Nyandarua County, but the soil scores 58/100 and needs targeted management to reach full potential. At an average pH of 5.38 the soil is moderately acidic, below Jute Mallow (Mrenda)'s preferred 5.8–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Jute Mallow (Mrenda)'s requirements, so a maintenance fertilizer programme is enough. Jute Mallow (Mrenda) prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Jute Mallow (Mrenda)'s full potential is about 5,000 kg/acre (~KES 250,000/acre at KES 50/kg), but at Nyandarua's 58/100 suitability a realistic target here is closer to 3,625 kg/acre (~KES 181,250/acre) unless the constraints above are addressed.
