Calcium : The Forgotten Nutrient
WHY CALCIUM IS IMPORTANT FOR TURFGRASSES?
Used for Sodium Abatement, Magnesium Reduction, and Aerating High CEC (tight) Soils. At the end of the day all nutrients are of importance and that is why we believe in balanced turf nutrition.
Calcium assists in the movement of minerals and nutrients around in the soil, which in turn aids in the absorption of these minerals and nutrients by the plant.
CALCIUM IN THE SOIL:
Primary nutrient in maintaining proper soil pH
Improves soil texture
Reduces soil compaction
Creates better environment for the proliferation of beneficial bacteria
Possible links to weed suppression
CALCIUM IN THE PLANT:
Vital constituent of cell walls within the plant
Strong cell walls significantly reduce disease and insect pressures and outbreaks
Enhances cell tissue strength for greater resistance to heat and traffic stress
Increases the availability of N-P-K and other vital micro nutrients
Used more by weight and volume than any other nutrient
Ca2+ is the most dominant cation in the soil
Should occupy 62-70%of the negatively charged sites of soil particles
Significant in building Brix in the plant
Influences 7 other nutrients in a positive way
Manganese (Mn), Potassium (K), Iron (Fe), Phosphate (P), Boron (B), Zinc (Zn), Magnesium (Mg)
INFLUENCING SOIL PH
Soil pH becomes self-adjusting when Calcium, Magnesium, Potassium and Sodium are in proper equilibrium (pH is the result not the cause of nutrient interaction in the soil)
Calcium tends to flocculate and help form stable aggregates which leads to good pore space for roots and microbes.
Calcium is a component of every living cell
Involved in cell elongation and division
Calcium is the main constituent of all cell walls and membranes, hence essential for :
protection against insects; and
