OUTLINE: This trial is measuring sediment loss for a range of in-furrow sediment control options.


METHODOLOGY:

The trial site is located in south-east Queensland. Row length is approximately 100 m on a 4% slope. The treatments are as follows:

  1. No Treatment
  2. 4 Pines in a diamond pattern
  3. 5 Pines in a row across the furrow
  4. 5 Pines in a row across the furrow with a whole plant above
  5. 5 Pines in a row across the furrow with living mulch (Jap Millet)
  6. 3 Whole plants
  7. Living Mulch
  8. Polymer – Stonewall
  9. Coarse sugar cane mulch with polymer glue

The trial was planted on the 4/5 December 2019 and received 14 mm of for December (6 mm and 8 mm). On 22 January 2020, the images below were taken. The rainfall prior to the photo was recorded as:

  • 16/01 – 30 mm
  • 17/01 – 38 mm
  • 18/01 – 38 mm
  • 21/01 – 38 mm

The photo pairs below show the top and bottom of the same row for one of the replicates. In total there are 4 replicates.
