UREA is the type of fertilizer with the highest nitrogen ratio with a nitrogen ratio of 46%. It is white in color and odorless and has a pril or granular structure. UREA can be used in all plants during the production period.UREA is the type of fertilizer with the highest nitrogen ratio with a nitrogen ratio of 46%.

It is white in color and odorless and has a pril or granular structure. UREA can be used in all plants during the production period.
Plants can take up UREA nitrogen directly. However, in order for UREA to become more useful for plants, it must be broken down and converted into ammonium and nitrate. Considering this time, UREA application should be done earlier than other nitrogen fertilizers.
When UREA is excreted into the soil, it changes form by being broken down by urea bacteria present in the soil and becomes useful.When UREA is excreted into the soil, it changes form by being broken down by urea bacteria present in the soil and becomes useful.
During this transformation, if UREA, which is used as top dressing, remains on the soil surface, gas hen UREA is excreted into the soil, it changes form by being broken down by urea bacteria present in the soil and becomes useful.
During this transformation, if UREA, which is used as top dressing, remains on the soil surface, gas nitrogen losses of up to 30% can occur in a short time. This situation is especially observed at higher levels in calcareous and sandy soils. In addition, high air temperature also increases nitrogen loss.
In order to make effective use of UREA and reduce nitrogen losses, the applied fertilizer must remain under the soil. The important thing to note is that UREA does not touch the plant root or the planted seed.In order to make effective use of UREA and reduce nitrogen losses, the applied fertilizer must remain under the soil.
