  • Birge, Traci (2004)
    Productivity and quality of two grazed coastal seashore meadows in Eastern Uusimaa were examined between May and July, 2002. A total of 18 1m2 sample sites divided into four separate cutting regimes were cut by hand to simulate grazing in the meadow. cutting regimes of various intensities were used to simulate the short term effects of different grazing pressures on the quality and productivity of the vascular plant forage in the meadows. Samples were dried, weighed and analysed for digestibility and composition. Digestibility analysis was carried out using in vitro digestibility analysis. A CNS- 1000 Elemental Analyzer was used to measure carbon, nitrogen and sulphur content of selected samples. The results showed that cumulative above ground phytomass productivity (AGPP) was dependent upon both biotope and cutting regime in the large (40 ha) Bosgård meadow, and that interaction betweeen these two factors was significant. The results of the smaller (<2 ha) Majvik meadow were highly variable between replicates. This variation overshadowed possible effects of biotope and cutting regime and their interaction. Quality was dependent upon both biotope and cutting regime. D-value decreased over time.
