Uittreksel
Reseeding grassland in spring is less productive in the first year than reseeding in autumn, but it is better for environmental reasons because it represents a lower risk for nitrate leaching. In an experiment in Merelbeke and Bocholt (Belgium) grassland was reseeded either in April or at the end of May after one cut of grass. Evolution of NO3–N in the soil and dry matter yield in the sowing year were measured to determine the best period of grassland reseeding for both the farmer and the environment. In this experiment the DM yield of grassland reseeded on June 1st after 1 cut of the original sward was 0.9 t ha-1 higher in comparison with grassland reseeded on April 15th but it was only significantly higher in 1 location in 1 year. Moving the plowing date from April to June 1st resulted in significantly higher NO3-N concentrations in the soil during October – December 2012 and in October 2013 but the risk of nitrate leaching was still low.
