Abstract: 
This article describes the production of new types of liquid nitrogen fertilizers 
containing some derivatives of ferrocene, their use, their importance in agriculture. The growing 
demand for liquid nitrogen fertilizers in our country and in Europe, their effectiveness compared 
to granular nitrogen fertilizers, the solubility of liquid fertilizers in water and nitrate solutions 
compared to solid fertilizers, simplicity of preparation, low capital and operating costs, the lack 
of toxic waste in them, 2-3 times less labor in their loading, transportation and use in 
agriculture, even distribution in the soil, and a number of other advantages are mentioned in the 
article. The role of micro-and macro-fertilizers for the normal development of agricultural crops 
is invaluable. The research carried out by specialists in this field in our country is gaining 
importance.The article discusses some of the reforms implemented by our scientists in this area. 
In addition, information is provided on the reaction equations used in the synthesis of ferrocene 
derivatives, their positive impact on plant growth and development and productivity. Also, the 
goals and objectives of commodity chemistry created in our country, the results of current 
research are described in detail, and a new code number for liquid nitrogen fertilizers 
containing ferrocene products is recommended for the nomenclature of foreign economic activity 
in the proper implementation of export-import processes.
