Vegetal nutrition

A rational and balanced mineral nutrition is important when it comes to obtain the performance and quality objectives in all crops.

JISA catalog offers different nutrient balances for each phenological phase, putting at your disposal a range of high quality products, for the stability and rapid absorption of all the essential nutrients in plant nutrition.

The essential nutrients for plant development, according to the quantities required by the plants are the following:

Macronutrients and secondary elements:

• Nitrogen (N) favours vegetative growth and gives green color to plants.
• Phosphorus (P) contributes to the development of the root system and intercedes in several biochemical processes at the cellular level.
• Potassium (K) plays an important role in enzymatic activation, photosynthesis, in the synthesis of proteins and carbohydrates, in water balance at the cellular level. It favors the vegetative growth, the fructification and the ripening and quality of fruits.
• Calcium (Ca) stimulates roots and leaves development of roots and. It forms compounds in cell walls, is an enzyme activator. It neutralizes organic acids in the plant and reduces acidity in the soil.
• Magnesium (Mg) is the basic element of the chlorophyll molecule. It is involved in the synthesis and formation of proteins.
• Sulphur (S) is part of some vitamins, amino acids and enzymes. It acts in the cycle of carbohydrates and lipids. It intervenes in the redox mechanisms of cells.

Micronutrients:

• Iron (Fe) is mostly stored in chloroplasts, so it plays a fundamental role in the process of photosynthesis of plants.
• Manganese (Mn), is an essential component of the ribosomes of cells and participates in the reduction of molecules (CO2, nitrite and sulphate); In addition, it participates in the process of photosynthesis in the photolysis of water.
• Boron (B) is essential for pollen grains and pollen tube growth.

As well as it takes part in the synthesis of DNA.

• Molybdenum (Mo), is a basic constituent of enzymes that have to do with the biological fixation of N and the reduction of nitrate to ammonium.
• Zinc (Zn), is part of the amino acid tryptophan promoter of auxins and catalyzes the formation of carbonic acid in chloroplasts and cytoplasm during the process of photosynthesis. It is also essential to maintain the permeability of the cell membranes.
• Copper (Cu), although copper needs in crops are low, it acts as a metallic compound of enzymes and also take part in protein biosynthesis.
