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 Lancaster Farming 1 E.

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.
