Biodynamic Greenhouse Management and millions of other books are available for Amazon Kindle. by Heinz Grotzke (Author) Start reading Biodynamic Greenhouse Management on your Kindle in under a minute. Heinz Grotzke draws on over forty years of experience as a professional gardener to address the practicalities of greenhouse management.
This results in the emission of large quantities of methane. Agriculture also involves land-use changes: So the question becomes, how do we both reduce the amount of these greenhouse gasses we are producing, while pulling the carbon that has already been released back from the atmosphere and into the soil where it belongs?
The answer, ironically so, is through farming: And the best tool we can utilize to help us pull that carbon out of the air is already hard at work all around us, at least while the sun is shining: In the process of photosynthesis, light energy from the sun is absorbed along with carbon dioxide from the air by trees and plants. The oxygen is released back into the atmosphere, and the carbon is processed into sugar, transforming it from a gas to a liquid.
Some of this liquid carbon is utilized by the plant, and the rest flows down into the root system, where it is released into the soil.
Next to our oceans, soil is the biggest carbon sink on the planet. And here is where things get really interesting. There is this beautiful symbiosis going on beneath our feet, where the liquid carbon transforms into a solid, and is taken up by the microbiota—bacteria and fungi—that make up healthy soil.
In a handful of soil there are more microbes than there are humans on the face of the earth.
This microbiota returns the favor, releasing minerals and trace elements that feed the roots, encourage worm activity and build soil by creating carbon-rich humus. Building soil humus means the soil can then capture and store more water. The plant-microbial bridge delivers the trace minerals to our food that our bodies need to stay healthy and to ward off disease. Conversely, the presence of synthetic fertilizers discourages plants from pulling the carbon they need from the air.

Today biodynamics is practiced in more than 50 countries worldwide and in a variety of circumstances, ranging from temperate arable farming, viticulture in France, cotton production in Egypt, to silkworm breeding in China.

That beautiful exchange between root and microbes is broken, and the composition of the soil deteriorates. Plowing fields does added damage.
When soil loses carbon, it becomes hard and compacted, and its ability to absorb and retain water is dramatically impacted. This understanding is awakening our scientists, environmentalists and food advocates to a fundamental truth: The time has come to re-envision agriculture, not as a contributor to climate change, but as one of the remedies for it. The time has come to reimagine farming.
The answer to the future of farming may lie in its past. Demeter passionately believes that the Demeter Biodynamic Farm Standard offers a comprehensive agronomic blueprint for achieving these goals of regenerative agriculture and carbon sequestration.
First conceived of in the late s as an agricultural method offered as a response to the industrialization of farming, and still to this day promoted through an international collaboration of more than 20 countries, this tried and true standard offers coherent principles and easy-to-follow, common-sense practices that encourage farmers to be ecologists.
Carbon farmers, if you will.
