NITROGEN

Nitrogen (N) is the most important mineral element in plants´ nutrition. It is a constituent of amino-acids, proteins and nuclei acids and therefore, is fundamental in the growing process, in the division phase as well as the cellular elongation.

It is a component of the chlorophyll molecule directly influencing the photosynthesis, since it is part of the RUBISCO enzyme, which is fundamental in the fixation cycle of the carbonic anhydrous in the leaves.

Without an adequate Nitrogen supply, the crop excessively delays reaching a development to make it productive. In case of tree in production does not obtain a rapid renovation of the fruit wood for the following season:

Nitrogen deficiency symptoms in the plants are express as:

• Size reduction of the plants, flower and fruits.
