Soil. It's What You Find Under Your Feet!

What’s the difference between soil and dirt? Dirt is what you find under your fingernails. Soil is what you find under your feet. Think of soil as a thin living skin that covers the land. It goes down into the ground just a short way. Even the most fertile topsoil is only a foot or so deep. Soil is more than rock particles. It includes all the living things and the materials they make or change.
Soil Organic Matter (SOM) is that fraction of the soil composed of anything that once lived. Most soil lacks enough organic matter to support healthy plant growth. The Strive for 5% campaign was developed to help us increase SOM for healthy soil!
Truly healthy soil has between 3% and 5% organic material. That level can be maintained ONLY IF you add organic matter to the soil at the surface year in and year out. The plants, the earthworms, and the microbes need that additional matter to sustain a healthy soil. In the woods and prairies, that added organic matter came from dead leaves or dead grasses decomposing each year. We need to replicate that process in our lawns to be able to maintain a healthy organic content in our soil.

But few residential landscapes have soil this rich with organic material. The reality is that the soil under American lawns typically contains less than 1% organic material. This is because over a ten or twenty year period not only was no new organic material introduced, but the most abundant natural sources such as leaves and grass clippings were regularly collected and disposed of in our weekly trash pick-up.
A healthy soil needs a steady source of new organic material. It is constantly decomposing and yielding nutrients for the grass plants and must be replaced. The black fibrous material (called "humus") that results from the decomposition of grass clippings and other organic material eventually has little food value left. But, it does have enormous value in aerating the soil, in storing water, and in feeding key microorganisms needed for other tasks.

While leaving grass clippings on the lawn provides some organic material, it is not enough to consistently provide 3 or 5 %. You must provide more. And how may I provide more organic matter, you might ask? The answer is simple; STA Certified Compost! Applying a layer of compost to lawns twice a year (called 'top dressing') adds vital nutrients, increasing soil's water holding capacity and soil structure. Top Dressing is widely recognized by landscape pros as the most environmentally responsible method of lawn care. Compost is also beneficial for erosion control, turf establishment, tree & shrub backfill mix and used in flower & vegetable gardens for vibrant blooms and healthy veggies.
STA Certified Harvest Blend Compost can do many things for your soil. Benefits include:
·        Improving soil structure, porosity and density to ensure a healthier root environment
·        Infiltrating heavy soils, thereby reducing erosion
·        Increasing water holding capacity of soil so that water is used more efficiently
·        Stabilizing pH and improving the soil’s ability to hold nutrients
·        Supplying valuable microbes, micro and macronutrients and organic matter to the soil environment
·        Helps to suppress soil-borne plant pathogens
·        Binds and degrades specific pollutants
We encourage you to schedule a visit to one of the participating STA composting facilities to get a first hand look at the commercial composting process. To locate a facility in your area, visit http://www.compostingcouncil.org/ & click on "Buying Compost" under the Resources tab. Please visit the US Composting Council’s website for more information on the Consumer Compost Use Program and all issues related to compost.
