Effect of fertilisation renovation on the production capacity of permanent grassland
From the experimental study of fertilization renovation (after its three-year absence) on production capacity of seminatural grassland in the area of Strážov Hills (Middle Slovakia, height above see level 640 m, association Lolio-Cynosuretum Tx. 1937, time of experiment 1997-1999) it follows that ye...

| description | From the experimental study of fertilization renovation (after its three-year absence) on production capacity of seminatural grassland in the area of Strážov Hills (Middle Slovakia, height above see level 640 m, association Lolio-Cynosuretum Tx. 1937, time of experiment 1997-1999) it follows that yearly application of doses 60-120 kg N(+PK)/ha leads to a rapid renovation of production feat at high yield stability and production effects by infused nutriens (increase of yield 15.3 or 13.6 kg dry matter/kg NPK, 23.1 or 19.1 kg dry matter/kg N). Within the dose interval 120-240 kg N(+PK)/ha, the values of average production 1 kg N (8.64 kg dry matter) fall to almost one half in comparison to the interval 60-120 kg N(+PK)/ha, and when compared to the dose interval 0-60 kg N(+PK)/ha, they fall to almost one third. When alternating applications of nutrients in particular years (PK-NPK-PK, PK-0-PK, N60PK-N120PK-N240PK) the yield variation in time (Vx = 25.56-43.64%) increases enormously in comparison to habitual application of the same nutrient doses (Vx = 5.26-10.42%). |
