This report provides information on the effects of agricultural practices on soil pH and soil carbon (C) from three long-term agricultural trials in the Douglas Daly region of the Northern Territory (NT). The three trials studied the effects of tropical pasture species and mixtures on beef production (1973-2011), tillage practices for wet season arable cropping (1983-2000), and mixed cropping rotations with differing ley pasture species and grazing intensities (1994-2000). This report has recommendations for the effective use of soil carbon and pH to monitor soil quality in agricultural soils in the NT. The results of these trials may be relevant to other Australian regions [PDF 699 KB, 108 pages]. #
