Neighbour Effects in the Move from Trial Strip to Whole-Paddock Clay Spreading on Water-Repellent Sands
A paper from the School of Underlying Conditions reconstructs twenty seasons of clay spreading on the 91 holdings of one sand-plain district whose ground is at least one-fifth water-repellent sand, and places each holding on the district soil survey's map units. Any adopting neighbour raises the odds of a first trial strip by about half, but only a neighbour on the same mapped sand moves a trial to whole-paddock spreading (an odds ratio of 2.31 per such neighbour), most strongly where the unit boundary is abrupt; of the 23 holdings still at the trial stage in 2023, 17 began without one.
