The book "Improvement of energy efficiency of ultraviolet disinfection of liquid media in agricultural production" by Alexander Valenitovich Kotov is a unique study, which combines advanced technologies and practical solutions to improve the efficiency of agricultural production. In today's world, where environmental problems and food safety are becoming more relevant, this work opens up new horizons in the field of agronomy and ecology. In his book, Kotov invites readers to look into the world of ultraviolet disinfection, which becomes an integral part of modern technologies for processing liquid media. The author analyzes in detail how ultraviolet radiation can be used to destroy pathogenic microorganisms in water and other liquids, which is especially important for agriculture, where water purity directly affects crop quality and animal health. Kotov not only describes the theoretical aspects, but also shares practical recommendations for the introduction of these technologies into real production. The book will be of interest to a wide range of readers: from undergraduate and graduate students of agronomic and environmental specialties to practicing agronomists and entrepreneurs engaged in agriculture. It can also attract the attention of specialists in the field of ecology and environmental protection, as it addresses issues of sustainable development and efficient use of resources. If you are interested in modern methods of improving the quality of products and reducing the negative impact on nature, then this work will be a real find for you. The topics raised in the book cover not only the technical aspects of ultraviolet disinfection, but also broader issues such as sustainable agriculture, food safety, and environmental protection. Kotov emphasizes the importance of integrating new technologies into traditional farming methods, which allows not only to increase productivity, but also to reduce processing costs. He also discusses the economic aspects of the introduction of ultraviolet disinfection, which makes the book useful not only from a scientific but also from a practical point of view. The author's style is distinguished by clarity and accessibility, which makes it easy to assimilate even the most complex concepts. Kotov skillfully combines scientific data with practical examples, which makes his book not only informative, but also fascinating. This work will be an excellent addition to the library of anyone interested in modern technologies in agriculture. Alexander Valenitovich Kotov is an author who has already established himself in the scientific community, and his work on agronomy and ecology are of interest to specialists and students. If you are familiar with his other works, you know that each one is filled with in-depth research and up-to-date data that could change the approach to traditional farming methods. In conclusion, the book “Improving the energy efficiency of ultraviolet disinfection of liquid media in agricultural production” is not just a scientific publication, but a practical guide that will help you understand modern technologies and their application in agronomy. If you want to be one step ahead in your field, this book should take its rightful place on your shelf.
