Urea (46-0-0) is the most widely used nitrogen fertilizer worldwide, with the highest nitrogen content, reaching 46% in amide form. It is used to enhance the growth of all crops, as nitrogen is essential for protein formation, increasing photosynthesis and improving yield and quality of production.
The use of urea is flexible as it is suitable for use as a basic or surface fertilizer, through dispersion, fertigation and foliar nutrition. When applied to the soil, it is first converted to ammoniacal and then to nitrate nitrogen, providing both immediate and medium-term nutrition. However, to avoid losses through volatilization (ammonia), it is recommended to incorporate it into the soil or apply it before rain or irrigation.
Features and benefits
High nitrogen concentration
It provides a large amount of nitrogen per unit of product, reducing production costs.
Flexibility
Ideal for various application methods (soil, foliar feeding, hydroponics).
Slow release
It ensures prolonged nutrition, contributing to the stable growth of plants.
Adaptability
Compatible with all soil types and a wide range of crops.
Urea is recommended for a variety of crops, such as:
Cereals-Grains (wheat, barley, corn)
Industrial crops (cotton, sugar beets)
Fruit trees (olives, citrus, apple trees)
Vegetables (tomato, cucumber, potato, pepper)
Vineyards and other high-yield crops.
Indicative doses (per acre) and application methods:
Cereals (wheat, barley)
20-40 kg/ha, with two applications: 15 kg basic fertilization
and 15-20 kg surface application before earing.
Corn
30-40 kg/hectare, in two doses: 10-15 kg at sowing and 10-15 kg in the growth phase.
Cotton
10-15 kg/ha, before flowering or with fertigation in combination with irrigation.
Olives
1-2 kg/tree, in spring either superficially or by incorporation into the soil.
Tomato
2-3 kg/ha per application via fertigation, mainly during the period of foliage growth and fruiting.
Potato
15-20 kg/hectare, in two doses: during planting and before tuber formation.
Vines
10-15 kg/hectare, in the spring before the start of vegetative growth.
Notes: Exact rates depend on soil type, crop needs and climatic conditions. It is recommended to work with a qualified agronomist to ensure correct application and optimize yields.
