In carnation and other ornamentals, many physiological disorders are often associated with boron deficiency as one of the reasons in relation to calcium. How calcium interacts with boron uptake in the soil as well as in the plant and at what ratio we have to maintain to get quality flowers.?
No , I don't think , calcium in any way hinders boron uptake , unless calcium is concentrated in soil in form of calcium carbonate , where there is an excess alkalinity within the rhizosphere zone of the plant . Calcium being a second messenger , mostly having a role in signal transduction , plays an mutualistic role with boron uptake and use efficiency .
Calcium is reported to alleviate the boron toxicity , and boron improves the uptake of calcium .Based on this relation ship between the two nutrients , Ca/B ratio has been suggested as index to throw some light on balance between the two nutrients, across crops and soils .
