Soil suitability analysis based on Trans Nzoia's nutrient profile

Rice (Lowland/Paddy) can be grown in Trans Nzoia County, but the soil scores 58/100 and needs targeted management to reach full potential. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 4.5–7 band Rice (Lowland/Paddy) prefers, so no lime is usually required.
