Tillage Effects on Spatiotemporal Variability of Particulate Organic Matter
Figure 4
Seasonal changes in bulk density and volumetric water content. Arrows indicate the time of the tillage operations. The north field was converted from no-till to standard tillage in August 2003, while the south field remained under no-till. Both fields were then converted to minimum tillage in May 2005. Bars indicate the standard deviation of the mean.
