Nitrogen fertilizers are applied in cover to complete the nutritional requirements of crops in times of maximum need, key to development.
The choice of the type of fertilizer and the dosage depends on: The needs of crops, intense and punctual, in nutritious elements that are not easily retained in the soil.
The nutrients they contain: nitrogen supplementing with sulfur, magnesium, calcium and even micronutrients.
The chemical forms in which nutrients are found.
The characteristics of the soil and climatology.
Cultural practices and, especially, irrigation systems.
Trade name: UREA
Equivalent Grade: 46-0-0
Presentation: Granulated solid in bags
Urea is the most popular fertilizer.
It is the granulated solid with the highest concentration of nitrogen (N).
Nitrogen is essential in the plant.
It is part of every living cell. Plants require large amounts of N to grow normally.
It is necessary for the synthesis of chlorophyll and as part of the chlorophyll molecule, it is involved in the process of photosynthesis.
It is a component of vitamins and plant energy systems.
And it is also an essential component of amino acids; Therefore nitrogen is directly responsible for the increase of proteins in plants, being directly related to the number of leaves, shoots, stems, etc.
In cereals, nitrogen is decisive in the amount of protein in grains.
