The effect of soil pH on weeds

Recently Jessica Strauss caught up with Department of Primary Industries and Regional Development Principal Research Officer Dr Abul Hashem to talk about research he and Dr Catherine Borger have done on the interaction between soil pH, weeds and crops. Soil acidity limits productivity on approximately 50% of Australia’s agricultural land and several important weed species have a competitive advantage over broadacre crops on soils where the surface soil pH level is less than 5.5 or the subsurface pH is less than 4.8.

CSIRO’s Dr Cathryn O’Sullivan explains how weeds can manipulate the nitrogen cycle

Wild radish in flower

Dr Greg Rebetzke talks about research into high vigour wheat

CSIRO wheat breeder Dr Greg Rebetzke talks to Jessica Strauss about the research being conducted into developing a new high vigour wheat. What if we could have a wheat variety that could play the yield game and the competition game? High vigour kinds of wheat are not only good for competing with weeds; they also serve to shade the soil to reduce evaporation and ultimately increase water-use efficiency. Click through for more.
