In 2001, soil health and productivity were surveyed in riparian grassland buffers adjacent to Bear Creek in northern Story County, Iowa. The investigators resampled these 24 plots in 2014 using the same techniques to see what changes had resulted from the conservation practices applied in the intervening years.
Do soils within formerly cropped, perennial-grass riparian buffers continue to change after more than ten years of establishment?
The buffers sampled in 2014 had far better developed soil food webs than they (i.e., the very same plots) did 13 years earlier.
