No doubt you are hearing more about the trend toward using biologically based soil amendments versus synthetics or chemicals.
We have been using these natural products; testing the soil and observing that over time plants and turf areas are far more resilient and vital. Our experience has shown us that it is also a cost effective solution for healthier plants, gradually diminishing the frequency of fertilization and plant replacements.
And now, the scientific community is eagerly embracing these practices and have backed it up with research. We were most intrigued to read a recently published article in one of the industry trade publications about some exciting new research about these products.
A study conducted by the Professor of Agronomy at the University of Nebraska, Roch Gaussoin, found that they produce an equivalent response in terms of quality against 30% less quantity of a nitrogen based product. Moreover, the indications were an equal response with reduced rates of fertility.
Now this is only the below-ground benefits, mind you.
The above-ground benefits are also recognized for their contributions to air and water purity. Dr. Amaranthus, Associate Professor at Oregon State University says that environmentalists are getting excited because of the ability of these products to sequester carbon gases.
Studies have shown that the biological products increase the carbon content of treated soil 1% per year which Dr. Amaranthus says is huge. If you multiply that over millions of acres, there is a potential to reduce 27% of US carbon emissions.
The diagram below is taken from the Landscape for Life website, a collaboration of the Lady Bird John Wildflower Center and the US Botanic Garden. The blue arrows show how the element has always cycled naturally from one carbon reservoir to another. The red arrows represent carbon emissions due to human activities.
