چکیده انگلیسی
Slurry application positively affected soil fertility by increasing pH, as well as P, K and Mg availability, without any effect on organic C and the total N content. The mean annual herbage yield was 2.58, 3.56, 4.40, 5.75 and 6.09 t haâ1 in 0, 60, 120, 180 and 240 treatments, respectively. Concentrations of N, P and K in herbage slightly increased with slurry application, while the concentration of Ca decreased. There was no surplus of N, K and Ca up to an N application rate of 120 kg haâ1, and there was only a slight surplus of P and Mg. In S3 and S4 treatments, the main change in vegetation was an increase in graminoids cover, accompanied by a decrease in the cover of legumes and short forbs, without any significant effect on the species richness of vascular plants. Slurry application at annual rates up to 120 N haâ1 seems to be an acceptable compromise, and we recommend setting this limit for application of cattle slurry on Arrhenatherion grasslands.
