One of our goals when we first started farming here was to develop the farm as a self-contained nutrient system. Unlike the almost complete recycling of nutrients which can take place on a livestock operation, we are always amazed – even a little disturbed – to see how many tons of fertility and organic matter leave the market garden each year with so little returned to the good earth.
In the last few years I have noticed a lot of buzzwords being used around the grazing industry and in my readings, like sequestration of carbon, living soils, microbes, mycorrhizal fungi, biochar, regenerative agriculture, micro-biome and cover cropping. These all are in reference to techniques and terminology associated with awareness of soil biology. If any of you are like me, I sometimes will not ask a simple question because I don’t want to sound uninformed, so today I will start out with a simple explanation as to what the natural cycle of plant photosynthesis is and how a plant goes about getting the nutrients it needs to grow.
