The many faces of Calcium
Of all the nutrients plants need to grow properly, Calcium is arguably the most complex, and the simplest at the same time. It has major roles in plant cell structure and strength, through to helping hold fruit on the plant. It has an important role in soil structure, and is also a major part of soil chemistry.
To get inside the plant, calcium has a relatively small part of the root tip to enter. Subsequently damage of any kind to the root tips can prevent this from occurring. Uptake is also dependant on the plants transpiration rate so when the plant is under stress calcium intake reduces. And once it does arrive inside it cannot be repositioned to the new tissue so deficiency symptoms will show in the new growth or fruit. It all sounds a bit difficult, but under normal circumstances uptake occurs easily with very little energy cost.
When it comes to the soil, calcium belongs to a group of positively charged elements known as cations. These particles readily attach to clay, and alongside organic matter play a key role in forming good soil structure. However these cations do need to be present in in a particular balanced ratio for this effect to occur and calcium should to be the leader of the pack. Common opinions are that it should make up between 40 and 60% of the total cation volume, though it`s common for it to be as little 15 or 20%. If your soil is in this position the obvious answer will be to just add lime right?
Well not necessarily. Calcium is available in a variety of forms, and each one will have a slightly different effect on pH, so having an idea of where your soils pH sits will largely determine which one you choose. Lime will raise Ph, gypsum is generally pH neutral, and Katek Super Cal will very slightly lower pH, add in the different ways these products need to be applied and you are on your way to deciding which one is for you.
