In this episode Octavia takes a look at the Rhizosphere - a term given to the thin region of soil around a root hair where interactions occur between the root and microorganisms within the soil. Using the energy from light, the plant converts carbon dioxide and water into sugar and oxygen (6CO2 + 6H2O ⇒ 6O2 + C6H12O6) – this is photosynthesis.
Rather than using all this sugar for growth, they secrete some of it into the Rhizosphere, along with proteins and other substances – these sugary solutions are known as exudates. You might think that this is a waste of valuable energy, but they are actually attracting a microscopic workforce into the area, a colony of bacteria and fungi that help the plant extract nutrients from the soil that would have otherwise been unobtainable to the roots alone.
This marvellous symbiotic relationship leads to more complex interactions; it acts as a disease suppressant for the plant and forms the foundations of the soil food web. This web is vital for nutrient cycling and supports the growth of new life.
Modern farming practices can damage this soil food web, often destroying the delicate interactions between plants and their resident microorganisms. These practices are having devastating effects upon plant health, crop yields, soil stability and wildlife and are not currently sustainable.
At 59 Degrees we are paving the way forward for a healthier soil community. We believe that in order to promote healthy, happy plants, we need healthy, happy microorganisms.
We grow communities of these unique soil microorganisms that you can use directly in your soil and on your plants – from salad crops to mighty oaks. By adding this beneficial life to your soil you will transform the health of your plants.
