The effect of grassland botanical composition and (co-) grazing cattle and sheep on herbage production and sward nutrient utilisation
(2011-09-13)Plant diversity in grassland ecosystems has recently gained increasing interest, as plant diversity has often been found to be related to improved ecosystem functioning. So far, studies of ... -
Weed species diversity in cropping systems: Management and conservation strategies
(2010-05-26)Throughout the last decades, the intensification of farming practices accompanied by simplification of crop rotations, increased nitrogen fertilisation rates and weed control by highly ... -
Distribution of plant functional traits in a range of grassland formations differing in water and nitrogen availability
(2010-03-10)A database linkage between the BiolFlor and SynBioSys databases was applied to evaluate the general use and application of such linkages for grassland approaches, as well as to investigate ... -
Shrub encroachment of temperate grasslands: Effects on plant biodiversity and herbage production
(2009-12-10)In Europe, semi-natural grasslands are an important resource of biodiversity and are, therefore, of high conservation interest. They are often invaded by shrubs, and they are threatened by ... -
The Relationship between Biodiversity and Productivity in Permanent Grasslands and in Ley System
(2008-08-28)To investigate the effect of plant diversity on productivity, two experiments have been conducted. The first experiments aimed to study the biodiversity-productivity relationship in permanent ... -
Effects of local and landscape factors on grassland plant diversity
(2007-03-12)During the last decades, both the decrease of the area and the fragmentation of semi-natural habitats in Central Europe caused a dramatic decline of biodiversity at local and regional scales. ... -
Untersuchungen zur Variabilität und Kausalität des potentiellen Nitrataustrages beim Anbau von Zea mays in Deutschland.
(2005-03-29)The objective of this work was to analyse and determine the impact of important management and soil and site-related factors and their interactions on the risk for nitrate leaching following ...
