Each group of scientists according to their specialization studies the material on
mineral fertilizers and prepares it in the form of a lecture. To do this, selects
specific materials and forms questions for students on the topic.
The following lectures will be given in the course: first, a lecture by chemists
"Classification of mineral fertilizers" will be given with a demonstration of the
collection of mineral fertilizers and the amount of nutrients in mineral fertilizers.
Thetableisdisplayed.
Secondly, a report of geologists on the raw materials needed for the production
of mineral fertilizers will be presented, indicating mineral deposits on the map of
Uzbekistan.
The production of mineral fertilizers (technologists' report) is supplemented
with information about the equations of chemical reactions and the production of
