Description

Dried litter fall collected in the nutrient optimisation experiment 1477 Flakaliden. The litter is pooled into one composite sample per plot. Collection periods: • 2002-09-xx -- 2003-10-02. Sorted and weighed into four fractions (2021). • 2004-06-13--2004-09-29. Unsorted, total weight measured (2021). Plot 5A was excluded due to thinning. • 2004-10-06--2005-10-04. Sorted and weighed into four fractions (2021). • 2006-05-18--2006-10-19. Unsorted, total weight measured (2021). • 2007-05-07--2007-10-10. Unsorted, total weight measured (2021). • 2007-11-02--2008-08-20. Sorted and weighed into four fractions (2021). • 2008-10-15--2009-05-14. Sorted and weighed into three fractions (2009). • 2009-05-14--2009-10-02. Sorted and weighed into three fractions (2009). • 2009-10-05--2010-05-27. The base experiment sorted into three fractions (2012), other plots sorted into four fractions (2021). • 2010-05-28--2010-09-28.

Background information

• Between 2002 and 2008: litterfall was collected from four parcels (1A, 5A, 6A, and 16B), each with 10 traps. • From 2009 until autumn 2010: litter fall was collected from all plots except 14B, 16A, and the six girdled plots. • From autumn 2011 until spring 2023: litter fall was collected from 13 plots included in the so-called base experiment: 1A, 3B, 4A, 6A, 7A, 8B, 9A, 10A, 12B, 13A, 14A, 15A, and 16B. Litterfall has been sorted into three or four fractions during the winter seasons of different years (three fractions = needles, twigs and cones, other, four fractions = needles, twigs, cones, other).

Associated trials

Events

  • Miscellaneous 2021: An additional portion of the litter fall was sorted into four fractions (needles, cones, twigs, other).
  • Miscellaneous 2012: Some of the material was sorted into three fractions in 2012 (needles, twigs and cones, other).
  • Miscellaneous 2009: Some of the material was sorted into three fractions in 2009 (needles, twigs and cones, other).
  • Accident 2003: Litter fall collected during the early years of the experiment and stored in the office building at Flakaliden was destroyed when the building burned down.
