Topsoil, or often misspelled as top soil, is the top layer of soil on the surface of the earth that usually runs about 5 to 6 inches deep. It’s full of organic matter, which makes it richer and darker. The organic matter is where new plants get the bulk of their nutrients from, making topsoil the most valuable layer of dirt. If you require soil with even more organic matter, consider our topsoil mix with 1/3 aged manure.

Common Misconceptions of Topsoil
You might see other sand & gravel companies advertising their topsoil being free of weed seeds, and think that their products are superior. Unfortunately, there is no way to screen out weed seeds, so what some companies do is to treat their soil with heat. Not only is this a costly process, it also kills the microorganism that is beneficial to plant growth, which means it isn’t good topsoil anymore.
Another common misconception is that fertilization is not required when using topsoil. This is simply untrue, even if the soil you acquired is top quality and suitable for plant growth. This is because nutrients in soil deplete overtime, and every batch of topsoil from the same gravel company would still vary in nutrient levels. To ensure successful plant growth, it’s best to do soil test and amend it according to the type of plant you plan on growing.
