Long-term field experiment V140 Muencheberg from 1963 to 2009 - Plots

General description of the Long-term Field Experiment "V140": The long-term field experiment "V140" was established in 1963 at the experimental site of the present Leibniz Centre for Agricultural Landscape Research about 50 km east of Berlin in the district Märkisch-Oderland. The area is characterized by dry periods, particularly during early summer. Weather data for the running period of V140 are available at the DWD (station number 03376) ftp://ftp-cdc.dwd.de/pub/CDC/observations_germany/climate/daily/kl/historical/tageswerte_KL_03376_19490101_20171231_hist.zip. The V140 represents one of the few still active long-term field experiments on sandy soil. During the running period just smaller management measures changes have been done. Whereas originally questions to yield increase measures on sandy soil were in focus, present research put more focus on the effects of organic and mineral fertilization on essential aspects of the soil fertility. The V140 is around 0.5 ha and is located on a flat area. Before the establishment of V140 the site was cultivated uniformly. According to the German Guidelines Soil Assessment (Bodenschätzung) the dominating soil types are slightly loamy sand and sand (Sl4D and S4D). The most common soil sub type is Haplic Luvisol. The experiment includes 21 treatments: 5 levels of mineral fertilization combined with 4 levels of organic fertilization and one control.
