Growing Rice (Lowland/Paddy) in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Rice (Lowland/Paddy). Garissa's soil (pH 7.96, alkaline) gives Rice (Lowland/Paddy) a suitability score of 2/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Rice (Lowland/Paddy) (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 7.96 the soil sits above Rice (Lowland/Paddy)'s preferred 4.5–7 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. Rice (Lowland/Paddy) prefers clay soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 mm/year — well below Rice (Lowland/Paddy)'s minimum of 1100 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Rice (Lowland/Paddy) is the #61 soil match of the 106 crops we assess for Garissa County. Rice (Lowland/Paddy)'s full potential is about 2,600 kg/acre (~KES 260,000/acre at KES 100/kg), but at Garissa's 2/100 suitability a realistic target here is closer to 65 kg/acre (~KES 6,500/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.

Top dressing guide
Garissa's nitrogen (0.61 g/kg) is 51% of the 1.2 g/kg Rice (Lowland/Paddy) needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
