Michael McGill has been conducting an evaluation of this seasons wheat crop in Goomalling WA. In conjunction with Ian Clarke, this is a long-term trial that Michael plans to continue for five years.
The trial is situated on deep white sand and rainfall has been low this year. Despite the circumstances, Ian and Michael have noticed two standout observations so far.
Plant sap brix testing observations show that the control paddock had a brix result of 9, whereas the treated paddock had a brix result of 13. The Brix reading is a standard method for measuring sugar content in an aqueous solution. This means that the treated plants had a higher sugar content as compared to the controlled plants.
Sugars have a central regulatory function in steering plant growth. Thus, higher sugar content improves the regulation of protein synthesis, which in turn increases plant productivity. Sugars are used by plants in counteracting common adversities in their natural environment, such as frost.
