In conventional agriculture the main aspect to consider is that nitrogen is an essential mineral related to productivity and fruit quality, being part of a great number of organic compounds such as amino acids, proteins, nucleic acids, chlorophyll, etc.
▶ Deficiency of this element is manifested by yellowing of the leaves, lack of sprouting, very abundant flowering and, what is worse, a manifest lack of fruit set, which results in an extremely reduced harvest. The fruits that are harvested are generally smaller.
Adequate nitrogen supply for citrus crops, especially for resource-poor producers especially for resource-poor growers, can be linked to an abundant but unused organic resource such as manure, compost, worm castings and others.
The period of absorption of the roots, starting in a reduced way at the beginning of spring, achieving an increasing increase in absorption with a peak in mid-summer. The spring period is the period of greatest demand, due to the presence of the flower, fruit set and multiplication of the fruit cell.
This period between the maximum absorption and the highest demand, must be covered with sufficient supply for its accumulation and use in adequate time. The most used fertilizer in citriculture is urea, which has a high solubility once added to the soil.
That is why this fertilizer should be added in fractioned form according to the recommendations of the soil analysis, and depending on the productivity of the plot, and accompanied, if possible, with organic fertilizers that will act as absorption regulators.
