Teachers and researchers of different universities have shared or transferred technology and experience with field technicians and carried out many experiments, thus completing the technology for the sustained effect of the slow-action urea fertilizer by making use of several additives.

After confirming the technical production processes in a short span of time through several technical discussion sessions, the researchers of Kim Chaek University of Technology completed the technical tasks for various kinds of equipment and devices necessary for the processes in cooperation with technicians and designers of different units.

Scientists of the agricultural science research units are also engaged in the research into developing high-efficiency slow effective fertilizer and determining the scientific fertilizing system and rate.

The Hungnam Fertilizer Complex is providing necessary conditions for developing and producing the fertilizer.
