Dra Ingham I want to make a reference a your
paper that I saw in this page The Soil Foodweb: It's Importance in
Ecosystem Health I want to put the bibliography
about something tha you say 'Soil Foodweb Significance
In restoration studies, the lack of appropriate
inoculum is more likely to be a problem than in other situations where
sources of appropriate VAM spores are near-by. Thus, the presence of at
least 1 to 5 spores per gram of soil is adequate for most crop fields.
When the number of spores falls below one per gram, then addition of
compost containing high numbers of VAM spores (for example from an
alfalfa field, or other legume), or inoculation of VAM spores from a
commercial source generally results in positive effects.
Percent VAM colonization
At least 12% of the root system of grasses,
(i.e., most crop plants), should be colonized by VAM in order to obtain
the minimum required benefits from this symbiotic relationship.
Colonization upwards of 40% is usually seen in healthy soils. VAM
colonization can limit root-feeding nematode attack of root systems, if
the nematode burden is not too high. A great deal knowledge of the
relationship between plant species, VAM species and soil type, including
fertility, is needed in order to fully predict the optimal relationship
between crop plant, VAM species and soil.' How I
can write the reference about it thanks
