Landwirtschaftskammer Niedersachsen (LWK) is in charge of most of the dry region in the Northeast of Lower Saxony. That means ca. 300.000ha of irrigated land, covering nine counties. Most of the area is classified from EU as “Objective-1-Area” (EU-Convergency Objective). As a result of former EU-Projects (EU-Interreg-Northsea-Programme) and national projects (financed by the German Ministery of Eduction and Research) it became obvious, that in the future the need for irrigation will increase and it will extend to further regions.

During the early 1990 in Northeastern Lower Saxony, the last fields were opened with irrigation infrastructure. This was organized by local irrigation boards. It typically means: deep groundwater–wells (10-100 meters), subterranean pipeline-networks to all fields, and finally electricity (rarely diesel engines) for pumping. The predominant technology to apply the irrigation water is by 300 – 700 m flexible windable pipeline from a reel wagon. That is equipped with one gun- spray-jet at the tubes end, with a working width of 70 m, and driven by hydraulic power. This system is at the time used at about 95 % of the fields in Lower Saxony.

LWK coordinated the activities, with especial focus in the pilot area in Nine Counties of Northeast Lower Saxony . LWK also tesedt WEAM4i developments on thier experimental Station in Hamerstorf.
