Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

mycolabadmin

This study examined how beneficial fungal partners of plants (arbuscular mycorrhizal fungi) affect soil bacteria that convert ammonia to nitrate. Using 50 different soils from Czech agricultural fields, researchers found that these fungi suppress ammonia-oxidizing bacteria, but surprisingly this happens even when ammonia levels in soil are high. The findings suggest the relationship between these microorganisms is more complex than simple competition for nutrients.

This study examined how a beneficial fungus called arbuscular mycorrhiza affects bacteria that break down ammonia in soil. Researchers tested 50 different agricultural soils and found that the fungus suppressed ammonia-oxidizing bacteria populations. Interestingly, the presence of the fungus actually increased ammonia levels in soil while decreasing nitrate, suggesting the relationship is more complex than simple competition for nutrients.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

This study examined how a common soil fungus called arbuscular mycorrhiza affects bacteria and archaea that process ammonia in agricultural soils. Using 50 different soils from the Czech Republic, researchers found that the fungus suppresses ammonia-oxidizing bacteria but not archaea. Interestingly, the fungus actually increased ammonia levels in soil rather than depleting them, suggesting the suppression works through mechanisms beyond simple competition for nutrients.
