Calcium is an absolutely wonderful element. Calcium is the buffer that keeps our blood at a pH of 7.4, so nutrients can be electrically inducted into our cells. It is also the element that carries those nutrients into the cells, releases them, and goes back for more. Calcium ions are what make nerve synapses work. DNA can’t be synthesized without Calcium. Calcium can bind to seven oxygen locations on a protein while still holding on to a water molecule and then release them all easily. No other element can do that. Calcium carries the heavy trace minerals like Manganese into the plant from the soil. Have you ever bought a peach or a nectarine where the seed was split open and inside you could see this little shriveled kernel instead of a plump embryo? That seed didn’t form because it didn’t have any Manganese. Every viable seed requires a molecule, maybe only a single atom, of Manganese to bring the electric charge to the seed and the magnetic force to draw the other elements into the seed. There may be plenty of Manganese in the soil, but if there is a shortage of Calcium to pull it into the plant the seeds will be sterile if they form at all. Or there may be enough Manganese and Calcium, but no Boron, and Boron is needed to move and direct Calcium. It all works together and each part is necessary.
Here’s the true fact: somehow they (whoever they are) managed to hide the important tip that Calcium is such an essential element in all living things? In plants, animals and humans, adequate Calcium is absolutely needed for life. But just about the only mention Calcium gets in soil or hydroponics science is as a pH modifier or the name Cal on your Magnesium additives..
