Degradability Testing: Comparing Brands

In an effort to compare degradability between competitive brands, Keg River sampled extensively in 2010.  Many more locations were sampled than are shown here – these are however representative results:

Procedure:

  • Samples of products delivered to units were degraded with water for 24 hours.
  • Samples were washed through a 40 mesh screen to measure degree of disintegration (40 mesh has screen openings ~ 0.01” or 0.41 mm).  The less degraded portion is retained on the mesh (see tray on the right below). 
  • Samples were dried, weighed, graphed and photographed.

Results:

5g of each sample activated by 3 ml water

After screening, this is the remainder of the samples that is larger than 40 mesh

Details:

  • Three different competitor locations were sampled
  • Better clay results in more thorough disintegration
  • Degraded particles smaller than 40 mesh provide very high surface area exposure to soil microbes for faster conversion to plant usable sulfate.  Finer particles yield better results.
