WA growers with non-wetting soils are adding clay and using a spader for incorporation to lift the productivity of their farms
Trevor Syme is positive about the future productivity of his cropping program despite climatic conditions being far from optimal over the past two years.
Claying at a rate of 260 tonnes per hectare and using a rotary spader to incorporate the clay is a cost effective and profitable way of ameliorating non-wetting sands on a farm near Goomalling, according to preliminary trial results.
Remediating sandy soils with clay-rich subsoil can generate substantial crop yield improvements, provided appropriate methods are followed.
Remediating sandy soils with clay-rich subsoil can often generate substantial crop yield improvements, providing appropriate methods are followed.
Remediating sandy soils with clay-rich subsoil can generate substantial crop yield improvements, provided that appropriate methods are followed. In fact, trials in South Australia and Western Australia have recorded yield improvements of 20 to 130 per cent across cereal, lupin and canola crops in the years following clay additions. Grain...
