Growing Green Grams in Mombasa
Soil suitability analysis based on Mombasa's nutrient profile
Yes, with the right inputs — Mombasa is moderately suited to Green Grams. Mombasa's soil (pH 6.24, slightly acidic) gives Green Grams a suitability score of 70/100. Match fertilizer to Mombasa's nitrogen and phosphorus levels for the best result.
Mombasa County is a solid choice for Green Grams, with a soil-match score of 70/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–8 band Green Grams prefers, so no lime is usually required. Nitrogen (0.95 g/kg), phosphorus (8.4 mg/kg) and potassium (136 mg/kg) all meet Green Grams's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Green Grams, which favours sandy loam. Green Grams's full potential is about 400 kg/acre (~KES 48,000/acre at KES 120/kg), but at Mombasa's 70/100 suitability a realistic target here is closer to 350 kg/acre (~KES 42,000/acre) unless the constraints above are addressed.
