FOSFORNS VÄXTTILLGÄNGLIGHET OCH DESS EFFEKT PÅ MYKORRHIZA / Phosphorus in soil and its impact on arbuscular mycorrhiza
A pot experiment was performed to study the impact of phosphorus in soil on the development of Arbuscular Mycorrhiza (AM) on ryegrass. The soil used in the experiment was fertilized with different phosphorus fertilizers three years before this experiment.
Fertilizer-P (easily soluble calcium phosphate) added as a storage supply (45 kg P/ha) affected AM negatively and lime did not compensate for the negative influence of fertilizer-P. Smaller amounts (13 kg P/ha) of fertilizer-P seemed not to influence the AM.
