Abstracts |
The effect of five rock phosphates with different
solubility (from Algeria, North Florida, North Carolina,
Senegal, and Morocco) and that of single superphosphate (SSP)
alone or with lime was investigated on the root colonization of
red clover with indigenous arbuscular mycorrhizal fungi (AMF).
In a pot experiment, the phosphorus (P) sources were applied at
four rates (0, 100, 400, and 1600 mg total P2O5 kg(-1) dry soil)
to an acidic sandy soil (Nyirlugos) and to an acidic clay loam
soil (Ragaly). The arbuscule content of the roots was more
sensitive to various rock phosphates than the infection
frequency. No mycorrhizal colonization of roots was observed in
the Nyirlugos soil at the 1600 mg P2O5 kg(-1) level of SSP or in
either soil at the 1600 mg P2O5 kg(-1) level of SSP+lime,
indicating that the mycorrhizal dependency of the host was
eliminated by the highest soluble P concentrations in the soil
