    The paper discusses the gradual transition from conventional tillage through reduced tillage to no-tillage while creating favourable conditions for increase of organic matter. The paper suggests crop and tillage method rotation for a period of five years in order to facilitate this transition. It also reviews tests of soil physical properties which can help farmers determine how their soils are changing and what effect the change of tillage method has on them.

    Harvesting of oil seed rape and avoiding of big grain losses require specific adjustments of the machine. The basic level of grain machine losses comes from the entrance device (header) added the losses from the following up devices in accordance of the applying technological scheme. The mean feature for each device is its exponential character, which means, that they are very sensitive to the parameter changes, from which they depends on. By suitable prescription of the technological adjustments and adequate selection of the machine type those losses can be reduced below the agritechnical requirements.

    Harvesting of oil seed rape and avoiding of big grain losses require specific adjustments of the machine. The basic level of grain machine losses comes from the entrance device (header) added the losses from the following up devices in accordance of the applying technological scheme. To reduce the seed losses into the harvester it is recommended to operate with the header in accordance with the rotor or hybrid type thresher-separator device.
