RESEARCH ON THE INFLUENCE OF CHEMICAL FERTILIZERS ON TEMPORARY SHORT-EXPLOITATION GRASSLAND
AbstractAveraged over the two years of experimentation (2012-2013) separate influence of the mixture of species on short-exploitation temporary grassland production was reduced, meaning that the production of the 4 mixtures were close. Whatever themixture, theunfertilized variant, consideredcontrol, has been acquiredvery lowproductionof only2.44tha-1 d.m. Throughfertilizationwith100 kg/haN(backgroundof 50kg/haP2O5 and50 kg/haK2O) were made5.41t ha-1 d.m., which represents an increase of2.97tha-1orin therelative numbersby122%. The dose of 120 kg/ha N applied in two rounds (80 kg in the spring + 40 kg after first harvest) increased production by 2.08 t ha-1, the amount harvested per unit area being 4.52 t ha-1d.m.
