Molecular formula: NH4N2O
Granulated urea fertilizer 46%. It is basic nitrogen fertilizer with a wide range of applications, practically used for all cultivated plants, both pre-sowing and top dressing. It can be used as soil and foliar fertilizer. It is characterized by a high nitrogen bioretention; low nitrate potential and long period of availability in soil for plants.
It is used for foliar feeding in the form of foliar spraying with an aqueous solution.
The dose and concentration of the solution should be selected according to the species and stage of development of the fed plants.
Root feeding with urea is also possible, but due to the need to convert the amide form to the ammonium form, which is available for plants, and then to the nitrate form, the absorption process is much longer and slower than with foliar application.
The scope of application of urea as a soil fertilizer is very wide and covers practically all crops.
It can be used both before sowing and top dressing.
The efficiency of using urea as a nitrogen source on very acidic, strongly alkaline soils or just after liming may be significantly lower than on comparable areas with neutral pH soils.
Urea as a nitrogen fertilizer is especially recommended in fruit and vegetable crops due to its low nitrate potential.
Urea remains in the soil for a long time in the form of ammonium available to plants.
As a result of its use, we do not observe excessive accumulation of harmful nitrates in the soil and plants.
Also, groundwater is not polluted with these hazardous compounds due to the use of urea.
Another advantage of this nitrogen fertilizer is that it supports the uptake of phosphorus from the soil and reduces the excessive uptake of potassium.
The application of nitrogen in this form causes lush rooting and faster plant development compared to other forms of application of this element since the post-emergence period.
Application of urea in the form of soil increases the resistance of plants and increases the yields and their biological value.
