  < p > The ZALF Focus Area - Paulinenaue is located 30 km west of Berlin . ZALF manages 60 ha of grassland on a lowland fen research site founded in 1949 by Prof. E.A. Mitscherlich in the Havelländisches Luch.</p > < p > Own herds of different animal species e.g. Uckermärker cattle are available for grassland use.</p > < p > The ZALF research station Paulinenaue is located on the edge of the 56,000 ha NATURA2000 ( SPA ) site Rhin - Havelluch ( < a href="https://www.bfn.de / natura-2000 - gebiet / rhin - havelluch">see BfN NATURA2000 in Germany</a > ; < a href="https://lfu.brandenburg.de / lfu / de / aufgaben / natur / natura-2000 / managementplanung / spa - rhin - havelluch/">see LfU SPA site Rhin Havelluch</a > ) This area represents the shallow- to medium - depth fens of northeastern Germany , which are predominantly used as grassland . ZALF 's agricultural landscape research questions related to grassland and peatland are comprehensively addressed here . < /p > < h1 > Main research tasks that are addressed in this focus area:</h1 > < p>1 . Acting as a coordinating body for scientific work in the field of fenland research or grassland and fenland ecology . Implementation of a long - term data collection program on landscape - relevant variables on typical grassland sites of the ZALF study area.<br/ > 2 . Supervision of a grassland long - term experiment and a groundwater lysimeter installation with 103 lysimeters and 15 different soil types of Northeast Germany for parameter quantification and validation for grassland and landscape models.<br/ > 3 . Collaboration on ecosystem - based landscape analysis and related research projects in close cooperation with all program areas and working groups of ZALF . Securing grassland - specific experimental and mapping work in the landscape.<br/ > 4 . Organizing large - scale landscape ecology experiments involving agricultural and processing enterprises with a focus on production ecology research , development and redesign of the cultivated landscape . Active participation in the establishment of new landscape laboratories of ZALF and contribution of existing knowledge and experience.</p > < p > The fenlands of the Rhin - Havelluch have essentially developed as marshy and silted - up fenland with waterlogging by groundwater . The 300 years of drainage in connection with intensive use in the past decades has contributed to a considerable extent to the fen shrinkage and mineralization of the organic soil substance . Therefore , the subject of research is particularly the protection of the fenland body and extensive agricultural land use practices that conserve abiotic and biotic resources.</p > < p > The soil physical and chemical parameters of the study area can be characterized as follows:&#xD ; Soil physical parameters from the crumb horizon of the Rhin - Havelluch.<br/ > Organic matter content ( % ): 65 - 70 < br/ > Solids ( Vol.% ): 19 - 27 < br/ > Usable water capacity ( Vol.% ): 42 - 48 < br/ > Minimum air capacity ( Vol.% ): 11 - 12 < br/ > Ca ( % ): 2.4 - 4.8 < br/ > K ( % ): 0,07 - 0,10 < br/ > P ( % ): 0,07 - 0,11 < br/ > N ( % ): in organic matter 4.2 - 4.3 < br/ > pH value : 5.8 - 7.2</p > < p > The long - term mean of precipitation ( 1981 - 2010 ) is 536 mm . Average air temperature in this period is 9.2 ° C . < /p >
