Silty soils are composed of fine particles that are smaller than sand but larger than clay. They have a smooth texture and retain moisture well, making them fertile and ideal for growing a variety of plants. Silty soils often contain nutrients that support healthy plant growth, which is why they are commonly found in river valleys and floodplains. These soils can become compacted easily, which may hinder root growth and water drainage. To improve their structure, adding organic matter like compost can enhance their aeration and drainage capabilities. Silty soils are often associated with agriculture and gardening due to their rich nutrient content.
