Provide or retain set-aside areas in farmland Farmland Conservation

A replicated controlled study of former arable fields at six sites in Sweden (Hansson & Fogelfors 1998) found twice as many plant species in unfertilized compared to fertilized set-aside after 10 years (30 species in the least fertile site; 10 in the most fertile).  Annual cutting resulted in an increased number of species over the years.  The competitive success of plant species was related to management practices but there were also interactions between management and site conditions. At each site, two plots (10 x 20 m) were sown with a grass cover crop and two were left bare.  Each year, one of each pair had fertilizer added (equivalent to 150 kg N/ha) and half of every plot was cut and cuttings removed (late July).  Vegetation cover was assessed in the centre of each plot (8 x 1 m²; 1975-1986).

 

Reduce fertilizer, pesticide or herbicide use generally Farmland Conservation

A replicated controlled study of former arable fields at six sites in Sweden (Hansson & Fogelfors 1998) found that after 10 years, there were twice as many plant species in unfertilized compared to fertilized set-aside (30 species in the least fertile site, 10 in the most fertile). Cutting and planting a cover crop also had a positive effect on the number of plant species. At each site, two plots (10 x 20 m) were sown with a grass cover crop and two were left bare. Each year, one of each pair had fertilizer added (equivalent to 150 kg N/ha) and half of every plot was cut and cuttings removed (late July). Vegetation cover was assessed in the centre of each plot (8 x 1 m²) in 1975-1986.
