Bute, SA
Aims
To investigate amelioration options for sands that have low water holding capacity, low organic matter, low nutrient availability, compaction, non wetting and high risk for wind erosion.
Key messages
Treatments combining deep ripping with surface applied nutrition (synthetic fertiliser or chicken litter) delivered the highest marginal returns, ranging from $934 - $1249/ha over three years.
Depending on treatment cost these delivered return on investment ranging from 142 – 521%, over three years.
Placement of high rates of chicken litter (20t/ha) or matched synthetic fertiliser in the subsoil did not provide any yield increase over surface application.
