![]() ![]() Over fertilization of nitrogen and potassium will reduce calcium availability It is the carrier of all other nutrients to the plantĪs calcium content in the plant drops so can the protein, mineral and energy levels of the plantĬalcium is not considered a mobile nutrient, but can leach with excess nitrogen Plant available calcium determines the uptake of all other nutrients into the plant High levels of other cations such as magnesium, iron, sodium, and potassium can increase pH If transpiration is reduced, the calcium supply to growing tissues will become inadequateĬalcium is found in many minerals in soil, but is relatively insoluble.Ī common misconception is that if the pH is high, adequate calcium is present If the plant runs out of a supply of calcium, it cannot remobilize calcium from older tissues It is an important constituent of cell walls and can only be supplied in the xylem sap Once fixed, calcium is not mobile in the plant Only nitrogen and potassium are required in larger amounts by plants ![]() ![]() To associate calcium only as a buffer of pH is agronomicly ignorant.Ĭalcium stimulates growth of "soil life", including nitrogen-fixing bacteria.Ĭalcium helps create a healthy environment for your plants Some research even suggests that calcium plays a role in weed populations. The importance of calcium in the soil, includes the reduction of soil compaction, increased water infiltration, and helping to provide a better environment for the proliferation of beneficial bacteria. It plays a major role in the physiology of the plant, strengthening its physical structure, increasing nutrient uptake and protecting from disease. Calcium is rarely considered as a nutrient at all, only as a soil buffer to adjust pH.Ĭalcium should be considered the most important nutrient, and more than simply just a tool to move the pH scale. It is true that NPK is used in greater percentages than calcium, but calcium is used more by weight and volume than any other nutrient. Enjoy the read! This article was published in 2007. Below is an article that was written by a colleague of mine, Craig Dick, on the importance of Calcium. ![]()
