Which type of soil is commonly used in horticulture?

Loam is considered the ideal type of soil for horticulture because it is a balanced mixture of sand, silt, and clay. This composition provides optimal drainage while also retaining necessary moisture and nutrients, making it suitable for a wide variety of plants. Loamy soil allows for good aeration and root penetration, which is crucial for healthy plant growth.

In contrast, sand primarily drains quickly and lacks nutrient-holding capacity, which can lead to plants drying out or not receiving enough nutrients. Clay, while it can hold nutrients well, tends to retain too much water and can become compacted, limiting root growth and leading to poor aeration. Silt has a fine texture that retains moisture but can also become waterlogged and does not drain as effectively as loam. Therefore, loam is preferred in horticultural practices for its balanced properties, supporting healthy plant development.
