Probiotics For the Soil: Brew Your Own Local, Indigenous Microbes


| 2/11/2014 12:20:00 PM


The importance of soil health was recently emphasized by Robert Kremer in his presentation to the Cover Crop Research Symposium in Columbia, Missouri. During a day long seminar devoted to cover crops and the No Till methods of Agriculture, the importance of the subsurface ecosystem for plant health and crop yields was highlighted.

This USDA Soil Food Web graphic shows the importance of microbes in the soil.

Soil microbes provide numerous benefits to plants. These include suppression of pathogenic bacteria and fungi, and absorption of nutrients. If your soil is in poor condition as a result of chemical farming, or industrial agriculture, in addition to increasing organic matter, you may want to consider giving your soil a boost by adding local indigenous microbes. The recipe for creating a brew of your own batch of microbes is given below and is a chance to introduce you, and if you have them, your kids to the subject of microbiology.

Soil amendments are often peddled as a magic bullet. When it comes to building soil thee are no shortcuts. In order to increase the organic content of the soil, the research presented at the Cover Crop Symposium indicates that it takes 10 years to increase organic matter by one percent. A test of compost tea, soil microbes, and a control plot showed no difference in productivity as detailed in an research paper in the February, 2009 issue of HortScience Journal but there was no testing of nutrient values after harvest. A soil scientist that I spoke with at the conference suggested that just spraying the soil with a molasses solution, which provides and excellent food for soil microbes, would probably produce the same results. There is a possibility that local, indigenous, soil microbes might be of more benefit than commercially viable microbe preparations. Here is a recipe we tested at the Creek House Norganic Community Garden in Kansas City.
