Magnesium chloride uses in Farming/Agriculture
Plant growth requires nutrients found in atmosphere and soil. Plants depend on primary nutrients nitrogen, phosphorus, and potassium and secondary nutrients calcium and magnesium. Micronutrients boron, copper, manganese chloride, zinc, etc. bring total elements needed for plant growth to 16, not including trace nutrients cobalt, selenium, and silica that also support growth.
Ionized nutrients dissolve in water carrying positive or negative charges. Nutrients enter plants via the root system in solution. Nutrients are soluble, but they are not equal in terms of volume, some molecular combinations taking more room than others. Magnesium is a nutrient that is more compact. High soil pH reduces its availability to plants while low pH floods the plant, injuring it.
Role of Fertilizer
Nutrients delivered via fertilizers allow plants to use water, carbon dioxide, and solar energy in combination with specific plant supplements, those nutrients. This permits the plants to produce enzymes, proteins, and other essentials to nurture the plants.
Magnesium’s Role in Plant Growth
Chlorophyll photosynthesizes plant energy using positive magnesium ions taken in through the plant root system. This key nutrient turns on plant growth as an enzyme activator and has functions in leaf health and seed production. When leaves yellow while their vein system is green, that plant is likely low in magnesium.
Chlorine’s Role in Plant Growth
Chloride is also necessary for photosynthesis, entering plant root systems as negatively-charged chlorine ions. Plants need chloride to maintain leaf health too and is a natural for combination with positively-charged magnesium. Excess chloride will cause leaf burn.
Canadian Regulation of Fertilizers
Magnesium sources for fertilizer have been commercial limestone and magnesium wedded with oxide, sulfate, or chloride. Magnesium chloride along with all other fertilizers are regulated by the Canadian Food Inspection Agency (CFIA). The Agency assures that magnesium-containing fertilizers are safe for plants, animals, and our environment, whether produced in Canada or imported. Magnesium products are regulated as “Registered Farm Fertilizers,” “Registered Micronutrients,” or “Registered Supplements.”
Identifying “Organic” Magnesium Fertilizers
Magnesium cannot be synthesized because it is an atomic element. The real issue for organic farmers relates to the method of formulating magnesium chloride (and other magnesium alternatives) for organic crop cultivation. The CFIA oversees the Canadian Organic Standards (COS), a national approach to maintaining a substance list compatible with organic agriculture, first promulgated in 1999.
Magnesium Chloride Supplier
Magnesium is readily available as a macronutrient in both “organic” and conventional farming fertilizing applications. The CFIA registration and its COS are your assurance that your version of magnesium meets Canadian standards.
