The application of urea solution, even in high concentrations (3-5%), unlike other nitrogen fertilizers, does not cause burns in plants and helps to increase the protein content in grain.
When applying urea to the soil, it must be wrapped in a timely manner, because nitrogen loss from urea in the form of ammonia can reach 70%. To prevent nitrogen loss, urea is applied at an air temperature of no higher than 20-250C during the day and no lower than 10-120C in the evening.
Foliar fertilizing with urea is recommended to be carried out in combination with pesticides and microfertilizers in one working solution, which helps to reduce the factors of negative impact on plants of plant protection products and increases the effect ofherbicides andfungicides.
