NEW DIRECTIONS IN ANALYTICAL TECHNIQUES FOR THE ASSESSMENT OF MICROBIAL POPULATIONS IN CANELAND SOILS
By MIRA DURR, IAN WHITE, STEVE ROGERS, BEN MACDONALD and SUE WELCH
SOIL microbiological research is an area of increasing interest to agricultural
industries as it is a recognised component of soil health. Microbial populations
play a fundamental role in the cycling of nutrients in soil and are well
established as a component of structural soil stability, and thus agricultural
sustainability. The Australian sugar cane industry is aiming to increase its crop
productivity, decrease its inputs, and improve environmental performance. For
these reasons, soil microbial research is being increasingly recognised as a
means to provide practical management options improve industry performance
and viability. This paper provides an overview of techniques available to
evaluate soil microbial populations. Particular emphasis is placed on the
information that the emerging discipline of molecular bioscience can provide on
species composition and diversity.
