Effects of soil tillage
Excessively high work intensities did not lead to better results, not even with regard to soil loosening. In terms of the stability of the loosened soil structure, however, there are differences between the various implements. The increase of nitrate concentration due to tillage can be reduced significantly by planting appropriate green covers. Against the expectations,…
Soil tillage: energy input and seedbed structure
On soils requiring a high energy input for tillage, tillage methods show quite considerable differences with regard to work efficiency, energy requirements and efficiency. In all these respects, active (PTO driven) systems provide better results than passive implements. This is particularly true of the rotary tiller. Increasing the work intensity excessively has proved to be…
PE colour stretch films for silage bales
Within the scope of an investigation, we examined the suitability of colour PE stretch films for wrapping silage bales. Four types of films (white, black, olive green and brown) of two different manufacturers (Silotite and Teno-Spin) were used. We investigated the temperature rise beneath the film at a depth of 10 cm, the films’ influence…
Plastic silos – Recommendations for safe operation
Material fatigue and/or overloading can cause a collapse of tower silos of glass fiber reinforced plastic. As the silos are designed mainly for the relatively coarse-fibred grass and maize silages, the danger of collapse increases when the silo is filled with products of a high density, such as sugar beet pulp, coarse meal of maize…
Influence of single passes with high wheel load on a structured, unploughed sandy loam soil
In a field experiment, a sandy loam was subjected to single passes with a sugar beet harvester at two different soil water potentials and two different hopper fillings. The moist plot responded to a wheel load of 11,23 t with an increase in bulk density and pre-consolidation pressure as well as with a decrease in…
