Why is Calcium
so important?
Form. Taken up as ionic Ca2+, calcium is essential
for cell division and development of the active
root and shoot tips. Calcium plays a central role in
plant structure both above and below ground.
Function. Calcium is vital for activating enzymes
that promote growth and stimulate immune
system responses. In addition, calcium acts as
a binding agent that is essential to the structure
of stems, roots and fruits. Low calcium status
results in low vigor, slow development of
shoot and root, reduced nutrient recovery and
increased abiotic stress.
Symptoms. Low Calcium status affects rapidly
expanding tissue such as new leaves, roots and
developing fruit. Meristems fail to expand, and
growing points become necrotic. Leaf scorch, tip
burn and blossom end rot are classic symptoms
of low Calcium status, all of which are worse
during conditions that promote rapid growth.
Significance. As mobility within the plant is
very low, calcium demand can readily exceed
supply, creating stress which results in restricted
leaf, root and fruit development. As calcium is
taken up by a very small fraction of new roots,
anything that restricts root development will
affect calcium uptake.
Actions. Check soil calcium status and make
corrections if necessary. Maintain plant
phosphorous and zinc level to optimize root
development and calcium uptake. Foliar feed with
calcium during periods of heat or moisture stress.
The OMEX®
Cell Power®
range
of foliar applied Calcium
products continue to flourish
At OMEX® we take plant health very seriously
and strive to produce the most effective foliar
nutrients possible. OMEX's®
calcium range of foliar
applied fertilizers are tried and tested around the
globe. This calcium formulation is more readily
translocated through the plant than other foliar
calcium sources. The range includes: OMEX®
Calcium Gold, OMEX®
BoroCal Ultra.
Test results have shown that the OMEX®
Calcium
product range is more efficient than standard
calcium sources at placing calcium into the right
part of the plant at the right time.
