The Agricultural Industry

Calcium is one of the most important nutrients. It is important to build a strong cell membrane structure and play an important role in nitrogen metabolism, protein plays formation and absorption of potassium. Calcium deficiency is usually detected in growth areas such as the new top and root growth, and at the lower end of the fruit. Blossom-end rot (BER) in pepper and tomato is an excellent example of how cell membranes to reduce fruit quality and economic performance weakened.

Although the information is there, it is surprising how poorly informed about nutrition calcium. Although we have a practical understanding of its role as a soil conditioner, you remove the calcium deficiency in California agriculture can be difficult. Supply needs of the culture for the calcium is not as simple as calculating the lime requirement of soil. The availability of nutrients depends on many factors beyond total supply, such as pH, CEC, cation saturation with CCE, water availability and quality, to name a few.

There are two factors can affect the calcium.

Ca / Mg ratio can be limited by calcium availability of excess magnesium. Calcium is described directly below magnesium in the periodic table of elements “as” electro-chemical, which play a role in the dynamics of the cation exchange occurring in sharing the root zone. I personally believe that it pay no magic number for the Ca / Mg ratio, but the manufacturer must draw attention to the power of culture and consider the total amount of Mg as a possible source of interference with the absorption of Ca calculated in this approach the laboratory fertilizer recommendations assume an advisory role, the producer’s experience in reading the response of cultures.

Calcium is usually immobile once inside the plant. He rises from the roots through the xylem in the water column of the sweat moving the leaves, while only very few moves downward through the phloem. Because of this unidirectional flow near a steady supply of available calcium is necessary to ensure the integrity of the cells in the new areas of plant growth, how to support shoots, roots and fruits.

Calcium carbonate is an excellent choice of material for the intake of calcium for the relatively low cost, chemical purity and low power consumption required to dissociate it from its counterpart in carbonate. The redox reaction occurs in the presence of weak carboxylic acids beamed from roots and microorganisms in soils. They reduce the particle size increases the surface area available to be oxidized, increasing the use of calcium for plants.

In contrast to the approach of the laboratory analysis calculated diet, a small amount of micronized calcium carbonate is much more effective in removing calcium deficiency counterbalance the salts containing large amounts of high-quality materials liming rough. The smaller particles reach the roots, which deals with the mass flow of water through the soil pores, creating a buffer zone around the roots that effectively balances risk elements such as magnesium, sodium, aluminum, and the surplus. This explains why it makes economic sense, a smaller amount of fertilizer high in calcium do not use as the application of large amounts of calcium can reach the root zone until it is eroded by the environment.
