To identify on-farm management strategies to increase soil organic carbon (SOC) and quantify any associated risks and benefits in a grain production system.
In this trial the Facey Group wanted to determine whether:
• In 2013 there was no evidence of changes in soil condition or organic carbon associated with the application of compost at up to 3 t/ha in 2012.
• Potential changes in soil organic carbon and other soil properties will be determined in February 2014.
Property: Wade Hinkley, Tincurrin
Plot size & replication: 140m x 10m (control replicated x 4 strips)
Soil type: Grey deep sandy duplex (gravel below 25 cm); Grey Chromosol
(4% clay in 0-20 cm, increasing to 8% in 20-30 cm layer)
Soil pH: 4.8 in CaCl2 (0-10 cm), 4.5 in CaCl2 (10-20 cm), 4.7 in CaCl2 (20-30 cm)
EC: 0.09 dS/m (0-10 cm), 0.03 dS/m (10-30 cm)
Sowing date: NA
Seeding rate: Volunteer pasture in 2013
Fertiliser: 100kg/ha Super & Potash 2:1
Soil amelioration: In 2012 lime sand was spread at 0.75t/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.
