Abstract
Ridge tillage may improve organic row crop production in terms of higher yields andlower impacts on the environment. Ridge tillage is hardly ever used in Europe. In Denmark, growingof row crops in a ridge tillage system has been tested. In particular, organic grown maize has shownvery promising results. In some of the test plots, yields increased with up to 50 percent as comparedwith conventional flat seedbeds. On average, year 2005 results for organic maize grown on sandysoil showed increased yields of about 20 percent. Prior to putting the ridge tillage method into practice, a number of technical questions have to besolved. The project presented in this paper takes focus on these technical matters. Especially, theestablishment of a uniform ridge at varying soil types and conditions is important. The goal is todevelop a machine able to ridge up the soil, perform precision drilling and make a seedbed withoptimal germinating conditions for the seeds. Another important practical aspect is the machinecapacity and operational performance. In the ongoing project, a four rowed machine for putting upthe ridge and sowing in one operation have been constructed and tested. This machine has a widthof 3 m and a working speed of 4 km per hour resulting in a labour requirement of 1.23 h ha-1and afield capacity of 0.90 ha h-1. In practice, a machine with a width of 6 m and a speed of 5 km per hour may be realistic reducing the labour requirement to.0.58 h ha-1 and increasing the field capacity to1.93 ha h-1.
