SAGIT Deep Ripping Project Younghusband 2021 This trial was established to compare soil amelioration methods including deep ripping on non-wetting sands and to evaluate the cost/benefit of organic inputs such as chicken litter. Soil Treatment
Organic Input (Chicken Litter @ 5 t/ha)
Control
Nil Surface Spread
Control + SE14 Soil Wetter
Nil
Spading

Deep Ripping
Nil Surface Spread
Deep Ripping with Inclusion plates
Nil Surface Spread Direct Injected behind inclusion plate
Establishment improved by SE 14 soil wetter All treatments sown across 2020 crop rows (Partial onrow) Deep ripping, especially with inclusion plated led to variable establishment outcomes Spading gave small improvement over control but was exposed to severe erosion post seeding.
