When To Use Calcium Fertilizers

A crucial nutrient, calcium supports the cellular walls of plants and is essential for the formation of new cells. Frequent fruit illnesses like blossom-end rot, which is common in tomatoes and peppers, can result from a calcium deficit. For annual crops like vegetables, include winter shortly before digging. The calcium carbonate works during the winter and won’t harm new growth.

1. Benefits of Calcium Carbonate
   Increased availability of phosphorus.
   Increased nitrification and mineralization.
   Improved root system performance, nutrient recovery, and water use efficiency.
   Soil pH adjustment.
   Minimises soil levels of heavy metals.

Application Guidelines if direct to soil: 
Apply 250g/m2 if digging in the soil, and then sprinkle more on the top after digging. For 4m2 of soil, 1 kg of calcium carbonate will be sufficient to adjust the pH. For 100m2 of soil, 25kg of calcium carbonate will be sufficient to adjust the pH. Apply if the soil is acidic before growing perennial plants like lawns, shrubs, fruit, or trees. For an estimate of how much you need, check the pH of your soil. It may take years for an application to the area around established plants to have any impact. Before planting or sowing, pH levels should be adjusted. A soil pH test determines the soil’s acidity or alkalinity. pH 7.0 is regarded as neutral. The soil has an alkaline pH of over 7.0 and an acidic pH below 7.0. Granulated garden lime takes much longer to work than calcium carbonate in powder. Apply with a little more care to ensure that you receive even coverage. The ability of calcium carbonate to reduce heavy metals in the soil is one function that is well known to many professionals but may not be well known to the typical home gardener. This is typically only necessary if a soil analysis reveals the presence of heavy metals at levels in the soil that can be remedied. The removal of the soil would likely be the best option if the levels are too high. Heavy metals can be poisonous to plants in addition to possibly being toxic to humans. Instead of removing the metals from the soil, calcium carbonate “ties them up” so that they are less accessible for uptake by plants.

A crucial nutrient, calcium supports the cellular walls of plants and is essential for the formation of new cells. Frequent fruit illnesses like blossom-end rot, which is common in tomatoes and peppers, can result from a calcium deficit. For annual crops like vegetables, it is typically applied in the winter right before digging because calcium carbonate can take effect during the long winter months and won’t harm early development. For the best health of reptile shells, egg shells, farm animals, and domestic pets, ground calcium carbonate is the optimum calcium choice for your next animal feed or nutrition supplement composition. For the highest calcium content, our calcium carbonate is produced from a specialized, high-purity source. One role of calcium carbonate known to many professionals, but that is not necessarily common knowledge to the average home gardener, is its ability to mitigate heavy metals in the soil. Calcium Carbonate, in its powdered form, is much faster acting than granulated garden lime, but a little more care must be taken when applying to make sure you get even coverage. While many specialists are aware of calcium carbonate’s potential to reduce heavy metals in the soil, the average home gardener may not be as familiar with its function. Although calcium carbonate in powdered form works considerably more quickly than granulated garden lime, applying it requires a bit more care to ensure even application.
