The North American Long-Term Soil Productivity Experiment: Coast-to-coast findings from the first decade

Publications Posted on: May 12, 2016
The National Forest Management Act of 1976 mandates that a site’s productive capacity must be protected on federally managed lands. Monitoring the effects of management on a site’s productive capacity is not easy, and in 1989 a national program of Long-Term Soil Productivity (LTSP) research was established to assist National Forests toward this end.

The North American long-term soil productivity experiment: findings from the first decade of research

Publications Posted on: December 15, 2006
First decade findings on the impacts of organic matter removal and soil compaction are reported for the 26 oldest installations in the nation-wide network of long-term soil productivity sites. Complete removal of surface organic matter led to declines in soil C concentration to 20 cm depth and to reduced nutrient availability. The effect is attributed mainly to the loss of the forest floor.
