A mechanical mulching of soils during planting seedlings is becoming popular due to the shortage of labor. Evaluation of the dual action equipment for mulching soils along with planting of vegetable seedlings has been undertaken for qualitative performance of operations and productivity. The device was evaluated in production conditions for receiving its operational indicators. The deviation from a longitudinal axis line of planting seedlings was 5 cm and depth of planting seedling was 12 cm. The average field capacity of the combined machine in planting seedlings of vegetables was about 0.405 ha/hr. The average forward speed of machine was 2.03 km/h and thus average quantity of the planted seedlings was 271 seedlings/min.

The article provides a brief analysis of research results in the field of preparation and storage of silage feed. A brief description of the innovative energy – resource saving technology for the preparation and storage of silage in vacuum-processed containers made from an airtight film is given. The theory of compaction of feed in a container due to its self-weight of the silage and vacuum pressure is presented. It is shown that only vacuum gauge pressure acts on the top of a container, and the difference between the gauge pressure and the lateral and axial pressure, respectively act on the side and bottom of it. The practice of using vacuum-processed containers during silage has shown that a compacted layer is formed over the entire surface of the obtained monolith, which prevents the exit of juice and air from silage. With the porosity of the mass approaching zero, the density of grinded mass of plants approaches the density of their stems and further compaction of silage is senseless. Sufficient vacuum for silage is 60–70 kPa. The density of the compressed silage monoliths in this case is 700–800 kg/m3.
