    Laterite soils have a high clay content, which mean they have higher cation exchange capacityand water-holding capacity than sandy soils. It is because the particles are so small, the water is trapped between them. After rain, the water moves into the soil slowly. Palms are less likely to suffer from drought because the rain water is held in the soil. However, if the structure of lateritic soils becomes degraded, a hard crust can form on the surface, which hinders water infiltration, the emergence of seedlings, and leads to incre
