Read moreProspects in the use of nanotechnologies in plant growing
Nanotechnologies in agriculture are mostly associated with the reproduction of agricultural species and the processing and improvement of the quality of production. Nanotechnologies are already being used for disinfection of the air and of various materials, including food for animals, for purification of water in agro-ecological systems, for the treatment of seeds and cultures, for stimulation of the growth and the development of plants, as well as for the development of new types of packing materials allowing the continuous preservation of the ready products.
