The Impact of Organic Amendments on Soil Microbiology and Nutrients in a Three-Year Study of Trees Planted in Heavily Compacted, Poor Soil
Lamboy, Jana; Rivenshield, Angela; Bassuk, Nina
This project adds new dimensions to a three-year study of the effects of soil amendments and drainage on the growth of three species of trees planted in heavily compacted soil. The research was originally intended to compare soil physical parameters. Striking differences in the growth of trees planted with organic amendments led to questions regarding the nature of long-term benefits derived from adding food compost at the time of planting. The proposed tests will allow comparison of soil nutrients, microbiological activity, and presence of beneficial nematodes as an indicator of healthy soil. This is a rare opportunity to observe differences in a randomized experiment with replicated treatments prior to the harvest of the trees.
