Platform data

Overview

Detailed view

Data of repasturisation experiment with information about the location and treatments of the respective plots

Sketch of the site: different plot colour indicates different plot management
Data tables: treatment codes (a) control, (b) second control, (c) simulation of grazing (2x per year), (d) simulation of grazing (5x per year), (e) high fertilization , (f) low fertilization, (g) simulation of grazing (2x per year) + high fertilization, (h) simulation of grazing (5x per year) + high fertilization

FOR402-Metainformation:

"Basisdatei für Q2, Q3 und Q5: 52Plots zu 2500m², alle Bäume mit BHD>20cm mit Parameter: Art, BHD, Qualitätsansprache sowie waldbaulicher Behandlung; Verjüngungskompartimente mit 12 x 12 m befinden sich im Zentrum jedes Blocks für Bäume mit BHD 5-20 cm"

Original data: FOR402 (Phase 2) ID: 51004; Creator: Günter, Sven (AG: C4-C4, AG Mosandl)
 
This dataset has been migrated from the previous FOR402-Database to the FOR816-Database by the Central Data Management Z1/FOR816.
Please keep in mind that the migration included all avilable metainfomation which were accessible through the FOR402-Database. Nevertheless, it can't be guaranteed that no thematic misinterpretation occured in the data/attribute description.
There has been no further disciplin specfic control. In any case of ambiguity please contact the dataset creator.

Conclusion of the control experiment: 
-Spraying with Combo is the most efficient, low cost- and least manpower-requiring treatment. 
-On the other hand, the commonly used concentrations of this herbicide resulted in high mortality rates of all other components of the vegetation.
-Half of the application rate of Combo in combination with cutting reduces the impact on other vegetation dramatically, but is still highly efficient with respect to bracken.
-Black-foil & cutting, or cutting alone proved as the best method for bracken control if herbicides are not allowed and other vegetation should be preserved.

Treatments:
Asulam	with 400g/l active agent: 6l/ha
Glyphosat with 480g/l active agent: 4l/ha
Wilt Pruf with 25% active agent in solution: 6l/ha
Combo (PM) with 240g/l Picloram and Metsulfuron Methyl (60% p/p): 4l/ha
black foil:	6x6m/Plot
transparent foil:	6x6m/Plot
Cutting: only bracken leaves were cut, other vegetation remained in the plots
treatment combinations:
all treatments mentioned above were used in combination with cutting in alternating application
