Murlong seeder-based mitigation trial 2019. Best treatment: On-row sowing with paired-row plus seed zone wetter x4.1 increase over control. Wetter effect maximised with low in-furrow moisture (eg on the inter-row or with shallow-till knife point) #grdcsandysoils #SA_PIRSA #EPARF

Key message: Overcoming compaction and reducing repellence at Brimpton Lake (SA) led to wheat yield increases >1.8t/ha in 2018, five years after the soil was spaded 👌🏻

plot 55=on row +split wetter furrow surface and seed zone each 1.5l/ha bi-agra band

How was plot 55 established?

Main effect is on-row, but positive synergies with wetters and paired row (or winged point)

so looks good. What was the third picture treatment? That’s very handy

Seeding strategies improved barley establishment in non-wetting sand, Murlong SA. Control inter-row sowing, positive responses/synergies to on/edge-row sowing, deep moisture delving (230mm),winged opener, paired-row & 13 soil wetters @TheGRDC #grdcsandysoils #EPARF @MSF_Mildura

Moisture tracking on the back of the SA rainfall (14mm Nth YP). Preferential flow pathways in last years rows. Highlights the benefit of near row seeding on soils with restricted infiltration rates. With the added benefits of last years Fertiliser granules! #wetdry #soil #PAW

Shields have been used before. They cut out ridging but allow herbicide contaminated top soil to backfill in the furrow. Result=high crop damage.

Our Sandy Soils Trial at Ouyen is looking excellent, with some clear differences between treatments. #GRDCSandySoils @GRDCSouth
