Controlled drainage and crop production in a long-term experiment in North-Eastern Italy

Crop productivity under controlled drainage was studied in long-term field experiment with shallow fluctuating water table in North-Eastern Italy. Fourteen years of hydrological and yield data, including winter wheat, sugarbeet, soybean and maize, were collected over two monitoring periods (1995–2002 and 2006–2013). Controlled drainage (CD) and free drainage (FD) were tested in combination with open ditches (O) and subsurface pipes (P) systems....
