available in liquid, viscous, and powdered form on the market of the Russian Federation, there are certain difficulties with their dosage and uniform distribution in silage feeds. This is especially important for preservatives, which are used in small doses. Abroad, this issue is solved by using applicators which allow to make low doses of preservatives in the range of 125-250 ml/t uniformly [1]. In our country, to increase uniformity of preservatives distribution, water is usually added to a small amount of preservatives and they are applied by column centrifugal or diaphragm pumps at the rate of 3–5 l/t of silage raw material. It is not possible to apply preservatives in pure form with available metering pumps, as they cannot ensure uniformity and small doses of their application. In this regard, the installation for forage harvester for fine-dispersed application of preservatives by compressed air was developed in the Federal Williams Research Center of Forage Production & Agroecology. The results of laboratory studies are presented.
