Bacteria dominate ammonia oxidation in soils used for outdoor cattle overwintering

Popis výsledku v původním jazyce

In areas used for cattle overwintering detrimental effects normally associated with grazing are intensified. Among the alterations observed, increases on the N availability and soil pH may highly influence structure of ammonia oxidizing microbes and thusinfluence nitrification pattern in soil. To evaluate this assumption, we assessed the abundance and diversity of ammonia oxidizing bacteria (AOB) and archaea (AOA) in three sites with different degrees of animal impact (severe, moderate or no impact) ofan overwintering pasture by means of qPCR and T-RFLP of amoA genes. In areas where no animal impact could be identified AOA was dominating over AOB. However, AOB abundance increased as the degree of animal impact enhances, becoming most dominant in theseverely impacted site. Interestingly, the diversity of AOB was the highest in the severely impacted area, where AOA diversity was the lowest. Obviously the pressure imposed by altered environmental conditions created by cattle husbandry
