Impact of rotary spading, one-way ploughing, deep ripping and incorporated nutrients on second year crop responses locations
Aims

To investigate rotary spading and other soil amelioration techniques on yellow sandplain soils west of Moora.

Key messages

Grower adoption of rotary spading and mouldboard ploughing in the West Midlands has been steadily increasing.

  • This trial demonstrates the productivity and financial benefits that can arise from implementing rotary spading and indicates that the practice of deep ripping prior to spading appears to be worthwhile as not only does it remove obstacles and make spading easier it also appears to be a benefit to crop growth and productivity particularly in times of drought.
  • Soil compaction was a significant constraint on this site and deep ripping alone has shown an advantage. Ideally controlled traffic system should be implemented after deep tillage to prevent re-compaction and loss of these benefits.
