Vliv organického a minerálního hnojení na zlepšení degradovaných travních porostů v Národním hřebčíně Kladruby nad Labem

The aim of the work was to find out the influence of mineral and organic fertilization on the change of the quality of forage and to change the botanical composition and the yield of the forage on the poor stand in the National stud farm Kladruby N. L. In Kladruby n. L. in the autumn of 2014 on land 9502 a small-scale experiment was set up to verify the effect of fertilization on botanical composition and the production of forage grass with low yields of forage. The application of fertilizers was carried out in autumn 2014 and autumn 2015 on parcels measuring 4.0 x 4.0 with three variants in three replicates. After application of fertilizers botanical composition of stands and production of forage on the area of 1 m2 in the middle of the parcel before the 1st harvest in 2015 and 2016 was evaluated. The production of forage was evaluated together with the botanical evaluation of the stands. After the drying of the forage and its grinding on the laboratory mill, the quality of the forage was evaluated. According to the composting results, the yield of forage in 2016 to 10.2 t/ha and the quality of forage quality positively affected. Grass meadow was dominated by grassland in fertilized mineral fertilization and compost of parcels, compost fertilization also supports the occurrence of dicotyledonous herbs. Mineral fertilization promotes the occurrence and growth of grasses. mineral fertilization, organic fertilization, forage quality, forage production
