root hair

Researchers in different cropping regions are studying how to lift nutrient use efficiency by manipulating a crop's root systems.. In the south and west, Dr Manny Delhaize from CSIRO Agriculture has discovered that root hairs play a key role in improving the phosphorus use efficiency of wheat in acid soils... University of New England Associate Professor Chris Guppy is using 3-D computer-aided images (above) of cereal root systems supplied with phosphorus to identify whether they have the capacity to respond to the deep nutrient placement strategies being developed in the northern grains region...

Williams and Lipsett (1961) found that 50-60 years of wheat cultivation in NSW resulted in a loss of 30% of organic C but only 17% organic P. In natural soils the extent of net immobilization of P in organic matter and probably soil organic matter levels may often be set by the P supply in the parent material... Many authors only consider supply to occur by mass flow and diffusion (the interception component in Table 2.2 is combined with the diffusion component)... Plants can access a greater volume of soil through the formation of a mycorrhizal symbiosis...
