Fig. 2. Field capacity (-33 J kg-1) and wilting point (-1500 J kg-1) water contents in plots measured one year after first amendment application (a, March 1999), one month after the second amendment application (b, June 1999), and one year after the second amendment application (c, April 2000). Treatments with the same letters were not significantly different for each matric potential (
