Calcium is the most commonly overlooked compound when evaluating soil fertility. Calcium is also the second highest element by percentage in plant tissue. Disregarding this information does not make sense given the fact that no other single element is used more by weight and volume by plants than calcium. Literally, calcium levels in the soil and plant are the backbone of any effective fertility program.
The benefits of calcium to turf are numerous, primarily in regard to root and cell wall development. Research indicates that pathogens probe their way into a cell and inject their enzymes to weaken and eventually break the cell down, thus, a stronger cell membrane can actually slow down or even stop this attack. Calcium supplements the strength of the cell tissue for greater resistance to disease and adverse weather conditions. With today's new bentgrass varieties and lower mowing heights, there has never been a greater need for a calcium supplements like those listed below. Calcium allows plants to use sunlight, carbon dioxide, water, nitrogen and other minerals more efficiently and is also essential in starch conversion.
