NORCROSS, Ga.—Most crops
are mycorrhizal. The normal plant
root is colonized by beneficial
mycorrhizal fungi. Hyphae or fila
ments of these fungi can be 100
times longer than the entire plant
root system.
The symbiotic association
between plant and mycorrhizae
consists of an exchange of energy
for nutrients. The plant trades
energy in the form of carbon com
pounds for mycorrhizal assistance
in the uptake of nutrients includ
ing nitrogen, phosphorus, potas
sium, sulfur, magnesium, man
ganese, copper, zinc, calcium and
iron. The positive effects of
mycorrhizae on water uptake can
reduce crop moisture stress.
Mycorrhizae enhance plant
phosphorus nutrition. These fungi
extend the volume of soil sur
rounding each plant root where
nutrients are absorbed. The funi
also produce enzymes that help
convert organic phosphate com
pounds to plant-usable forms, pro
duce organic acids that mineralize
phosphorus and interact with bac
teria to solubilize phosphorus
from soil minerals. They are
involved in both the weathering of
insoluble phosphorus and in the
transport of phosphorus from the
soil to the plant.
The role of mycorrhizae in
enhancing phosphorus availability
differs substantially from that of
bacteria (rhizobia) involved in
biological nitrogen fixation. The
host plant-mycorrhizal association
is less specific than that of
legumes and rhizobia. Crop plants
are colonized by a wide range of

Mycorrhizae:
mycorrhizal species.
Mycorrhizal enhancement of
phosphorus availability is not usu
ally sufficient for the nutrition of
the host plant in soils with low
phosphorus levels. Phosphorus
fertilizer may be more effective in
supplying phosphorus to the plant
than mycorrhizal infection, but the
two sources also work together.
Mycorrhizal colonization
potential can decline in soils.
Fumigation, flooding, severe ero
sion or extended periods of bare
fallow may reduce the soil’s
potential for carrying mycorrhizae
of benefit to the crop. In Australia,
wheat phosphorus and zinc defi
ciencies after long fallow were
attributed to the loss of mycorrhi
zal colonization because of the
absence of host plants during the
fallow period. A similar “fallow
syndrome” has frequently been
noted in com following fallow in
the western Com Belt and Great
Plains. In Nebraska, com grown in
a fumigated soil showed pho
sphorus deficiency symptoms that
were alleviated by reintroducing
mycorrhizae into the soil at the
time of planting. In lowa and Mis
souri fields where crops were
killed by flooding in 1993, mycor
rhizal colonization potential was
reduced and starter fertilizer was
needed to avoid phosphorus defi
ciency symptoms in com even
when phosphorus soil tests were
high.
Mycorrhizal species of greatest
importance to agricultural crops
cannot be propagated in the
absence of growing plant roots.
