Decomposition-in-a-bag

site-e1-decomposition-bags-06012009-101805 I’ve set out 200 mesh plastic bags to examine decomposition rates and changes in litter chemistry of four types of litter: freshly killed Eichhornia crassipes and Typha domingensis (or dominguensis depending on what paper you read), and the past seasons accumulated litter from both aforementioned species. The bags sit, baking in the sun, attached to 3-m poles of PVC, which actually may be too short given the height of Typha (cattail) around here. The two photographs of bags below show some test bags I set out a few days ago, with tadpoles skimming around the surface of the bag… potentially attempting to enter and process the litter themselves. The other photo is designated site E1.

By the way, check out the excellent sewing job on the bags below… I can pump those out at a rate of 50 in 4 hrs now, although I started out at a much slower rate.
