Effects of Past Agricultural Practices on the Survival and Growth of Planted Trees1
- A. R. Gilmore and
- W. R. Boggess2
Four pine species (loblolly, shortleaf, red, and white) and three hardwood species (sycamore, green ash, and yellow-poplar) were planted on a recently abandoned agronomic experimental field in southern Illinois that had been used for 40 years to test crop rotations with various soil and fertilizer practices. After 7 growing seasons, pine survival and growth were poorest on the old limed plots (attributed to competition from weeds). After 6 growing seasons, hardwood survival and growth were best on the old limed plots. The effect of the tree species and the past fertilizer practices upon the chemical composition of the soil are given. Five years after plots were planted to pines, soil organic matter remained approximately the same on fertilized plots but nearly doubled on unfertilized plots.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
