Growing Guava in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Kitui County is a challenging environment for Guava (soil-match score 43/100) and will need significant amendment before planting. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band Guava prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Guava, which favours loam. Kitui receives approximately 500 mm/year — well below Guava's minimum of 700 mm — so supplemental irrigation would be essential for this crop. Guava's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kitui's 43/100 suitability a realistic target here is closer to 5,375 kg/acre (~KES 322,500/acre) unless the constraints above are addressed.
