variable rate gypsum

Catalogue: Ground Cover
An authority in soil science is among those suggesting closer long-term scrutiny of soil health using precision agriculture (PA) technology and on-farm trials to rectify areas where crops under-perform because of poor water use efficiency... Esperance-based David Hall, of the Department of Agriculture and Food, Western Australia (DAFWA), says root growth and water use by crops are often restricted by subsoil constraints including sodicity, salinity, boron toxicity and acidity which, to some extent, can be alleviated by applying gypsum... At the Mt Madden Field Walk in September 2010, Mr Hall observed the crop growth differences between the treatments highlighted the short-term benefit of gypsum in helping to increase crop emergence, root growth, water infiltration and water storage...

Finding the pieces that maximise water use efficiency.. The variation within the strips can be used to tease out soils that are more or less responsive to ameliorative treatments... There are also opportunities to develop other products from the soils and geophysics data sets that will help farmers increase their water use efficiency through improved recognition and remediation of constraints...
