A variety of bene®cial microorganisms are applied
to agricultural soils to control plant pathogens,
increase symbiotic or associative nitrogen ®xation,
increase plant nutrient availability, promote plant
growth through production of hormones or degrade
xenobiotic compounds. Variable results have been
reported for all types of microbial products, with vari-
ation in their eectiveness attributed to three main
causes: (1) presence of an already satisfactory level of
the organism(s) prior to inoculation; (2) poor survival
of the inoculant organism in the environment; and (3)
low quality of the inoculant itself. Low quality inocu-
lants contain insucient viable cells of the intended
microorganism, high numbers of contaminating micro-
organisms, or both.
Bene®t from bio-pesticides and bio-fertilisers
requires delivery to the ®eld of viable, active microor-
ganisms in high numbers, which requires high quality
inoculants. The carrier substrate is a critical part of
the product formulation and must be capable of sup-
porting high numbers of the intended microbe(s)
