Loam encompasses a variety of soil types, some granulated and nicely draining, while others may be thicker and have the consistency of mud.

Large plants and trees, including maples and poplars, are both commonly found growing in loam soil. Loam is a combination of small rock particles, organic matter and nutrients, often in ideal combinations for healthy plant growth. The granular soil retains water very easily, yet the drainage is well. Loamy soil is composed of 40 % sand, 40% silt and 20% clay.
