There’s an order to these things - one after another.
This chart is all about biochemical sequencing - the ordered uptake of nutrients from the soil food web that shows what must function in the plant before the next thing and the next thing works.
It is the culmination of Hugh Lovel’s work on biochemical sequencing in ‘quantum agriculture’. Many other great thinkers and scientists participated in the development of this too, of course.
Let’s keep it simple-ish. Here’s the story:
0 - Sulfur (not pictured) is the ignition, catalyzing all biological processes.
1 - Boron is the accelerator pedal, creating sap pressure.
2 - Silica is the highway, transporting nutrients through moving sap.
3 - Calcium is the truck that travels on the silicon highway in the traffic of magnesium, potassium, and sodium (the 3 other major cations), collecting and carrying the nutrients that follow in the sequence.
4 - Nitrogen is the precious cargo that enables complex chemistry and sets photosynthesis in motion with magnesium.
5 - Magnesium is the power plant, allowing chlorophyll to function.
6 - Phosphorus is the gas station providing chlorophyll a place to store energy during photosynthesis.
7 - Carbon, as CO2, combines with water, making sugar and releasing oxygen.
8 - Potassium is the tour guide bringing the sugars wherever they most need to go.
The later functions cannot be performed without the previous functions working. This is why the law of minimums is so real - plants can only perform as well as their most deficient nutrients, because those deficient nutrients will legitimately stop biological processes in their tracks.
So it’s good to get a soil test, ensure both broad presence and availability of nutrients, and (depending on your situation) sap test throughout the season to get a real view of what is going on. That way you can address your limiting factors, and unleash the plant's full potential.
