For that, alfalfa is harvested in mid-June by forage harvester, blown onto a compost spreader driving alongside and applied to a young root crop at rates of 70-140 m\u00b3\/ha.<\/p>\n<p>Transfer mulch was tested in the eastern part of Austria with Pannonian climate with long dry periods and occasional heavy rains. Ten days after the application of the 140 m\u00b3\/ha rate, measured soil water content was 1 % higher than on plots without mulch, which is the equivalent of 6 mm of precipitation. Transfer mulch in root crops is an important protection against evaporation, especially on hot days in early summer when the rows are not yet closed. At the same time, the mulch provides important soil protection during heavy rain events, in order not to lose the precious topsoil in root crops.<\/p>\n<p>A fertiliser effect on the mulched crop in the same year was not detectable.
