It is absorbed in the CA ++ image, either in the ground solution or directly from the calcium. The leguminous plants absorb larger amounts of the starch plants, which are inert in the plants.
The most important calcium deposits:
- Equation of acids produced from cells, especially the composition of protein and its transformations.
- Insert the intermediate plate of the cells into the image of calcium bactate.
- Works to activate the histopathological tissues in the developing summits.
- Essential in the composition of flowers.
- Affects the movement of carbohydrates in the plant.
- Increases plant resistance to disease.
Symptoms of calcium deficiency:
- Drying of developing peaks of branches and roots.
- Mitt spots appear on the leaves.
- Dry the edges of the leaves of the newly grown after the corrosive and then crashing.
- Pour the fruits with dead spots.
- The roots are short, twisted, and the roots of the top are dead.
Calcium intake in soil and plant:
The amount of calcium in the soil varies according to the soil quality, the origin of the soil and the prevailing marginal conditions, and its percentage of soils ranges from 1% in the humid wetlands to more than 50% in dry areas represented by calcareous soil.
Calcium Sources in Soil:
One of the most important sources of calcium is the soils and primary and secondary minerals containing calcium.
Calcium Fertilizer and Nectar Treatment:
- Calcium carbonate .
- Gypsum.
- Calcium nitrate.
- Super phosphate.
