Barley varieties with more effective rooting, improved water uptake and more efficient nutrient use have been singled out in research being carried out by the James Hutton Institute. Rooting performance of a number of spring barley varieties was being tested under varying degrees of soil compaction, said Alison Karley, a research scientist at the Institute. "Our aim is to exploit varietal differences in rooting to improve water and nutrient use efficiency."
