The functions of mineralsMinerals can perform three functions for the growth and development of plants, i.e. electrochemical, structure and function of the catalyst. The role includes the process of electrochemical ion concentration, menyeimbangakan makromelekul, koloida stabilization stabilization and neutralization of the charge. Structure of the role performed by the minerals in his involvement in the chemical structure of biological molecules or function in the form of polymer structure, e.g. calcium in pectin.

In its function as a catalyst, trace minerals are involved in the active (active site) an enzyme. Minerals-the minerals it contains the macro element groups (macronutrient) has a third role, whilst the micro elements (micronutrients) only supports the function of catalyst. The following is a function of the respective minerals and gelaja defisiensinya. The appearance of symptoms of deficiency against one mineral typically differ between plants that one with other plants.

(1) the function of Calcium (Ca) For plants.
In many of the mineral calcium in the soil, and plants in natural conditions are rarely deficient against these elements. Calcium is important in the synthesis of pectin on lammela middle. Calcium is also involved in the metabolism or the formation of cell nucleus and mitochondria. Calcium is very important for kebanykan plant and a severe lack of calcium can lead to damage and death of plants.

Meristematik is one of the regions most afflicted, because calcium deficiencies will inhibit the formation of new cell walls, so that cell division would be inhibited. Imperfect cell division or mitosis tampa formation of new cell wall, it will generate a multinukleat cells and are the typical symptoms of a deficiency in calcium. Cell walls, especially in supporting the structure of stems and petiol will be fragile, and the expansion of cells is inhibited.

Occurence of chlorosis of leaves along the edges of the young, the tip of the leaves bent down, the formation of roots is stuck, a symptom of deficiency of Ca. Catalytic role just a little calcium, namely as a motivator for some enzymes such as phospholipase. In addition, calcium plays a role in detoxification of oxalic acid crystals to form Ca-Oxalate that is often found in the plant cell vacuole.

(2) the functions of Magnesium (Mg) For plants.
Magnesium needed plants in large enough quantities. Magnesium has several important roles in plants, such as in the stabilization of riboson particles. Magnesium is seen in a number of enzymatic reactions with variable capacity.

The first reaction that concerns the transfer of phosphate from ATP, magnesium acts as liaison of the enzyme against the substrate. The second function of magnesium in changing the balance of the konstantan reaction in a manner bound to the product, for example on a specific kinase reactions. Third, the work of forming a complex with an inhibitor of the enzyme. Symptoms of magnesium deficiency are very characteristic.

The occurrence of bone between the chlorosis of leaves, can arise bright colors of pigments of red, Orange, purple, yellow or red and in defiseinsi severe necrosis areas or spots occurred. Because magnesium is highly soluble and easily transported throughout the body, a deficiency symptoms usually arise in the adult leaves.

(3) potassium (K).
Plants require large amounts of potassium, and a deficiency of this element against common in sandy soil or sand, because of its high solubility rate so easily lost because leached, potassium is a cation that is common in plants and is involved in maintaining the balance of ions inside the cell.

Potassium is not memililki’s role in supporting the structure of plants, but he acted as a catalyst.the synthesis of protein Many enzymes involved in the synthesis of protein, Jenis Protein not work efficiently if there is no potassium. Potassium is needed in large quantities, exceeds the needs of magnesium, and serves to activate the enzymes are free.

Potassium bound in the form of ions, in the enzyme pyruvate kinase, which is important in respiration in the metabolism of carbohydrates, so potassium becomes very important to the overall metabolism in plants. Potassium deficiency usually begins with a typical chlorosis shows spots on the adult leaves, and then propagate the younger kedaun. Potassium is one of the elements of the very cars at the plant.

Potassium deficiency is often also saw growth of rosette or like Bush. The reduced stem growth, become weak, and resistance to pathogens is declining, so susceptible to the disease. Symptoms of potassium deficiency is the result of Biochemistry tereduksinya proteins and carbohydrates, while the molecules small molecular weight such as amino acids, will accumulate.
