Fig. 2. The layout of a 20- x 20-m subsection (Site I) of the former compost area. The 1997 apparent soil electrical conductivity (EC_a) map is shown overlaid on the coring grid. Coring Rows B and D are based on known row locations; A, C, and E are located between the rows. (Adjusted northing = northing - 4487000; adjusted easting = easting - 570000)
