'Bacteria in living soil - the soil food web in action'

00:37 Jan 11, 2022
'Bacteria are single celled organisms that are the smallest of all of the microorganisms found in compost and living soil.  They are an important part of the soil food web because they cycle nutrients by eating organic matter and excreting nutrient rich waste that plant roots can absorb directly.  Many soil microbes feed on bacteria in the soil food web.  Because bacteria are high in nitrogen, the feeding microbes excrete the excess nitrogen in a form that can also be used directly by plants.  Bacteria typically measure 1 micron in diameter and can be round, oblong, or rod shaped.  In this video, thousands of bacteria are being pressed out of a piece of plant material (probably from the weight of the cover slip).  These bacteria are some of the typical microorganisms I find in the compost liquid I make with my AeromatiCo composter.  The AeromatiCo composter works by continuously aerating the compost with an industrial air pump that delivers 60 liters of air per minute.  Bacteria are one of many beneficial organisms that populate the organic matter and break it down into liquid compost.  I drench my garden beds and potted plants with the liquid compost which inoculates the living soil with a diverse set of microbes that keeps the soil food web thriving.  video details microscope: Olympus CX23 camera:  Olympus LC30 objective: 40x (400x total magnification)'
