✦ Synopsis
The connection between the quality of silo sheets and the ensiling process was investigated. For this purpose a test apparatus, which simulates and standardizes the radiation processes at the silo, was developed according to the principle of an &arti"cial sky'. Subsequently, an experiment was carried out with 130 kg portions of wilted grass, each compacted in plastic containers and covered with one of ten di!erent "lm types, de"ned by its thickness, colour and structure. The investigation shows that the temperature course in the silage is on similar principle between di!erent "lm types. Di!erences between the investigated "lm types were mainly discovered directly under the "lm (average temperature, temperature #uctuations, colour of the silage surface). Quantitatively, these di!erences do not seem to be very important, especially when taking the high standard deviations and the small e!ects caused in the middle of the containers into consideration. Further experiments are necessary. A test apparatus, such as the &arti"cial sky', o!ers a valuable supplement to standard testing methods in silage research.
