Impact of mouldboard ploughing and lime on deep yellow sand with acid subsoil locations
Aims

To measure the impact on crop productivity of combinations of lime and mouldboard ploughing on acidic deep yellow sand.

Key messages
  • In the first two seasons, 2009 and 2010, there was a strong and consistent yield increase in response to mouldboard ploughing. 
  • In 2011 the mouldboard plough plots on average yielded 300 kg/ha (13%) less than the unploughed plots.
  • This trial is an unreplicated demonstration so it’s hard to tell if the negative response is real or not. 
  • For further results please see attached trial report.

West Moora 2011

Sow rate or Target density 85 kg/ha
Sowing machinery

Site was ploughed in 2009 using a 3-furrow Kvernerland mouldboard plough with skimmers at a working depth of 30-35cm. The ploughed soil was then firmed with land packers. All subsequent seeding and management operations have used standard farm machinery as per the rest of the paddock.

Sow date 25 May 2011
Harvest date Not specified
Plot size 30m x 100m
Plot replication Not specified
Fertiliser

At seeding: Mapsc & MOP blend (70% Mapsc, 30% MOP) @ 55kg

Post: Urea split application early July and mid August @ 120kg

Herbicide

Treflan @ 2L/ha Sprayseed @ 1 L/ha, Logran @ 35 Grams (29 May); 500ml Paragon, 500ml Bromicide, 5 grams Glean (8 July)
