    Abstract

    Reseeding grassland in autumn is normally more productive in the 1st year than reseeding in spring, however it represents a higher risk for nitrate leaching. In an experiment in Merelbeke and Bocholt (Belgium) grassland was reseeded on August 15th, September 15th and October 15th in 2012 to establish. Evolution of the NO3-N concentration in the soil and dry matter yield in 2012 and 2013 were measured to determine the best period of grassland reseeding for both the farmer (installation new sward, yield) and the environment (risk nitrate leaching). We became the best combination by reseeding in September. Reseeding in August resulted in high NO3–N values in the soil in October- December and reseeding in October had a negative effect on sward development and yield in the year after reseeding.
