Nitrogen fertilizer with 46% urea nitrogen that must undergo the nitrification process to be assimilable by the crop, and this process greatly depends on the soil and environmental conditions. Depending on these factors, it can be used both during sowing and as a top dressing. It is applied mostly as a top dressing for any type of crop, preferably in warm areas to ensure a faster transformation process. During sowing, the application must be carried out as far in advance as possible so that the nitrogen is available as soon as the crop requires it.
