Calcium and Magnesium- Building Blocks of Life
Calcium and Magnesium as building block elements are paramount for proper tree reestablishment and sustainability. Calcium aids in cell division, strengthening of cell membranes, and cell wall structure for a strong, uniform framework to resist osmotic stress. With healthy cell walls, trees can translocate other nutrients throughout their structure from branch to branch, and from leaf to roots. Magnesium aids in the development and generation of chlorophyll, which provides colour in leaf and flower tissue. With more chlorophyll production, trees can generate more energy through photosynthesis to sink additional carbon and produce oxygen. Magnesium also aids the transportation and absorption of key nutrients, such as phosphorus and iron.
Where is my Calcium and Magnesium Going?
We all know that pH plays a vital role in mineral availability for nutrient uptake, however, the pHC of water sources is another factor to consider when managing elemental nutrient levels. pHC is a measurement of water’s potential to be a stripper or depositor of soil elemental nutrients. This calculation is based on the total cations, carbonates, & bicarbonates in your source water. If the pHC value is above 8.4 it is a stripper of soil nutrients and if below this value, it is a depositor of elemental nutrients. Easier said, the cleaner the water source (ex. rain & glacier run), the more potential it will have to strip elemental nutrients from the root zone. This variable plays a crucial role in managing the calcium and magnesium levels for newly establishing trees and shrubs.
