It is the most nitrogen-containing fertilizer among chemical fertilizers. When urea is given at a sufficient level, it affects flowering as well as root and stem development positively. By encouraging the formation of green parts, it allows the plant to benefit from the sun. Thus, it causes an increase in productivity. When given less, plant growth slows down, grain and fruit yield decreases. Urea should not be given close to seeds and roots. It can be used with planting in autumn and as top fertilizer in spring. When used as top fertilizer; Since there will be loss of nitrogen in the remaining urea on the soil surface, it should be buried under the soil with light tillage.
