Maize grows best on loamy soil. This is because loamy soil has a good balance of sand, silt, and clay particles, which allows for good drainage, moisture retention, and nutrient availability. Maize also prefers a slightly acidic soil pH between 6.0 and 6.8, which is common in loamy soils. Sandy soils drain too quickly and don't hold enough moisture, while clayey soils retain too much water and can become waterlogged. Silty-clay soils are heavy and compact, which can make it difficult for maize roots to penetrate and grow. Therefore, loamy soil is the most suitable soil type for maize growth and development.
