mighty microbes Soil microbes Microbes and Organic Gardening also help with water retention and disease suppression within the root zone.” Outdoor gardeners growing organically benefit from, or rely on, the presence of soil microbes in their gardens, many without even knowing the role these microbes play. Every living creature requires a food/energy source to survive and reproduce, and soil microbes feed and obtain energy primarily from the organic matter in the soil. Luckily, most organic fertilizers and amendments come in a form where further decomposition is required before they will be of any benefit to the plant. The microbes feed on this organic matter, breaking down the complex carbon bonds and, for lack of a better word, releasing the elemental nutrients held within the bond. However, if the soil does not contain enough organic matter for microbes to feed sufficiently, their numbers will undoubtedly be lower and they will likely congregate within a plant’s rhizosphere, consuming any root exudates and dead root cells that they can. 128 Maximum Yield USA | January 2015 Outdoor soil gardeners are not the only growers that can benefit from microbes in the soil, both outdoor and indoor container growers can as well. Growers who use an organic, soilless potting mix and some form of organic fertilizer stand to benefit greatly from the inoculation of beneficial microbes to the rooting media. Most organic fertilizers contain small amounts of elemental nutrients that are readily available to plant roots, but most of the nutrients will still be trapped within a carbon bond. The addition of soil microbes to the rooting medium will help the grower obtain a higher level of soil fertility and plant development. Soil microbes also help with water retention and disease suppression within the root zone. Natural evolution has embraced both competition and reliance as a way to cycle energy and nutrition throughout the land, sea and sky. The micro-organisms in the soil and the plants we grow are constantly involved in an often mutually beneficial game of give and take. And it is relationships like the ones between soil microbes and plants that helps keep life complex and perpetual.
