The Biochemical Sequences
We need to look at plants as machines and consider them as as living creatures.
Plants possess all the fundamental biological systems humans and animals have. Plants have a nervous system, circulatory system, reproductive system, immune system, etc. We need to understand that plants are not machines that can be bent to our will, but rather delicate natural systems designed to work and behave in specific measurable and predictable ways. We will never be able to optimize yield, quality, cost and effort without that paradigm shift.
Some years ago, Hugh Lovel, author of A Biodynamic Farm, began to realize there was an obvious hierarchy of how elements worked in living organisms. One thing had to occur before the next thing could happen, and so on down the line in a sequence.
Eventually he developed his theory of this hierarchy of elements, which he called “The Biochemical Sequence”.
The biochemical sequence can be hard to understand that's why I'll try to simplify it as much as I can.
The plant biochemical sequence begins with:
1 – Boron: Boron is the gas pedal of the sequence. It creates sap pressure which allows vascular fluids to move up and down your plant. It also activates Silicon – an often overlooked element in plant nutrition, but most definitely an essential one.
2 – Silica/Silicon: Boron provided the gas to move, but without a good highway system you would still get nowhere. Silicon provides the highway that facilitates efficient transport of all other nutrients.
3 – Calcium: Now we have gas and a highway system, we need something to travel our highway with. That’s where Calcium comes in. Calcium is the truck that travels on the silicon highway, collecting and carrying the nutrients that follow in the sequence.
4 – Nitrogen: Our Calcium truck holds precious cargo, our Nitrogen. Nitrogen is the basis of amino acid formation, protein chemistry and DNA replication. Once Nitrogen enters the equation, all sorts of proteins, enzymes, and hormones are produced, and other complex processes are set in motion.
5 – Magnesium: When the calcium truck arrives at its destination, the next thing on the agenda becomes the harvesting of energy. Plants do this with their chlorophyll, which ‘catch’ the energy from the sun in the process we know as “photosynthesis” (you know, our source of oxygen). Magnesium is essential in photosynthesis and can be looked at as the power plant, allowing chlorophyll to function.
6 – Phosphorus: After the chlorophyll caught the energy, this energy needs to be put to good use. As you may remember from high school biology: In photosynthesis, light, carbon dioxide and water are used to produce carbohydrates (sugars). Phosphorus plays an essential role here, as it allows an energy transfer from the chlorophyll. In this regard, we can look at Phosphorus as the gas station providing chlorophyll a place to store energy during photosynthesis.
7 – Carbon: Carbon, as Carbon dioxide (CO2), combines with water, making carbohydrates (sugar) and releasing oxygen.
8 – Potassium: Finally the produced sugars need to find their way to wherever they are needed most. Potassium is the tour guide in charge of just that!
