The fodder plants necessary in the field of animal husbandry have an essential characteristic, namely, the full use of plant mass, thus, imprinting their more efficient use in environmental conditions, it is among the intensive crops. The technology of conservation of fodder plants is useful for the capitalization of fodder from meadows and fodder crops, especially from the surfaces in the hilly and mountainous areas. The areas of the exploited meadows must ensure the necessary animal feed throughout the year. The article addresses certain experimental aspects of how it influences the environment of the aeration process in order to dry the fodder plants, a technology based on conservation, storage and maintenance of the nutritional qualities of the fodder. In the technology of drying fodder with heated air, it is necessary to continuously control the temperature in the fodder mass during the aeration process. The results of the experimental research were carried out in a technology to reduce the drying time from harvesting the fodder plants to obtaining hay at the storage humidity. A special aeration installation with a monitoring and control system of work processes was used to carry out the research. During the research the environmental parameters were analysed, the flow and the parameters of the aerating agent (temperature and humidity), as well as the characteristics of the feed mass structure: humidity, temperature, drying uniformity, obtaining information on their influence on reducing the drying time. In the controlled process of feeding aeration, conducted in climatic conditions, there is additionally an influence of the linear speed of the aerating agent on the duration of the process, the degree of humidity of the feed, at approx. 18%, recommended for preservation.
