Increasing Soil Aeration and Atmospheric Gas Exchange to Improve Soil Composition
Soil aeration is a natural process where topsoil absorbs gases from the air that are necessary for plant growth and productivity. If the ground does not get enough of these gases, soil nutrients are not available to the plants causing stunted root growth and low quality of plants and grasses. Areas of ground with high traffic become dense and packed down, dramatically lowering soil nutrients and therefore drastically lowering plant and grass growth. It is also important for aerobic soil microorganisms, which are key for many biological processes.
Soil contains the same gases found in the atmosphere, nitrogen, oxygen and carbon dioxide which are important for soil dynamics. The soil contains different proportions of gases, it is low in oxygen but high in carbon dioxide. There are many ways to increase the natural process of soil aeration and productivity.
One of the most cost effective ways to increase soil aeration and soil quality, is excavating and portable screening the topsoil. Topsoil screeners break up compacted and nutrient deprived soil thus restoring the nutrients needed for plant growth, making the purchase of new topsoil unnecessary.
Soil screeners are also environmentally friendly. Smaller dirt screeners that do not use harsh chemicals or larger gas guzzling machinery. It works by speeding up natures work, with little impact on the environment.
Good soil aeration is necessary for good plant growth, and dirt screens do the job in a low-cost and environmentally friendly way.
