PRW01 Fine Root Density and Turnover Based on Root Window Observations

Summary

Short name: 

PRW01

Abstract: 

Eight root windows (40cm X 40cm) were used to measure fine root production and decay over three years in a 2 factor-factorial experiment (Burning, Mowing). Root lengths were traced every two weeks during the growing season. Production, disappearance and standing crops (lengths) were calculated by 10 cm increments.
