The technology for conservation of hay is a useful method for exploiting the fodder from grasslands and fodder crops, especially from the higher zones of the hilly and mountainous areas. Animal breeders want the grassland areas they exploit to provide the necessary fodder for animals throughout the calendar year. Fodder plants have as essential feature the complete use of the plant mass, which gives a number of advantages, referring first of all to the more efficient use of the environmental conditions, which places them among the most intensive crops. The greatest losses of nutrients are generated when the hay is dried traditionally. These losses reach, in case of adverse weather, even 50−60 %, the drying time increasing to over 6−8 days. This paper addresses some experimental aspects on the way in which the environment influences the drying process of fodder plants, technology based on the conservation, storage and maintenance of the nutritional qualities of the fodder. The results of the experimental researches were realized within a new technology for shortening the period from fodder plants harvesting to obtaining the hay at the storage humidity. When the research was carried out, a pilot ventilation installation with a system for monitoring and controlling the working processes was used. In the research conducted were analysed the parameters of the environment, the parameters of the aeration agent (temperature and humidity), as well as the characteristics of the fodder mass: moisture, temperature, uniformity of drying, and thus information regarding their influence on the drying time was obtained.
