At TopSoil Pros we regularly test our topsoil for the right balance of properties to ensure we are selling a Premium Quality Topsoil.
The three main properties that influence topsoil are Soil Texture, Organic Matter, and pH.
SOIL TEXTURE: Soil texture refers to the proportion of sand, silt, and clay found in soil, and greatly affects the suitability of topsoil. Texture determines soil structure (the way particles group together) aeration, compaction and tilth. Soil structure, in turn, affects how much moisture soil will retain and how far root systems can reach and grow. Texture is influenced by how much organic material, such as decomposing leaves, plant matter, fungi, and bacteria is present and able to enrich the soil with nutrients.
Sand: The right percentage of sand allows for water to flow through the soil at a desired rate. Too much sand, though, will cause the soil to have a low water and nutrient-holding capacity.
Silt: Silt is composed of tiny pieces of minerals and decomposing organic matter that are rich in nutrients. The organic particles in silt are critical for aeration in the topsoil. Silt particles have a finer texture than sand, and allow the topsoil to retain moisture.
Clay: Tiny particles in soil, smaller than those of sand or silt are considered clay. Small amounts of clay are beneficial to soil texture, but too much clay causes soil to drain poorly, resulting in plants not receiving the proper amount of oxygen they need to grow and thrive. Too much clay makes soil thick, gummy and difficult to work.
ORGANIC MATTER: Quaility topsoil should have an organic matter content of 5% or greater. Organic matter is stable vegetative material or residue that has been fully digested by microorganisms and is resistant to further decomposition. It is essential in the formation of soil structure, providing the nutrients needed for plant growth, reducing compaction, and allowing for greater drainage and porosity.
pH pH is an indication of the acidity or alkalinity of soil. pH of 7 is neutral – values below 7 are acidic, and values above 7 are alkaline. Desirable pH is between 6.0 and 7.5, although some acid loving plants will thrive in soils of 4.5-5.9
