In 2012 lime sand was spread at 0.75 t/ha prior to compost. Compost was combined with 0.2 t/ha of lime sand for ease of spreading. In total each treatment received 0.95 t/ha of lime sand + variable rate of compost prior to seeding.
3 compost rates (1, 2, 3 t/ha spread in 2012 and 3 t/ha in May 2014)
