Characterization of soil microbial population dynamics in newly constructed sand-based root zones. Soil erosion and conservation in global agriculture.

The results are in agreement with previous studies which shown that agricultural practices, such as mineral N fertilizer application, significantly alter AOB populations, which subsequently impact nitrification and production rates of nitrous oxide N 2 Oa potent greenhouse gas, in crop production systems Kowalchuk and Stephen, Therefore, the study of these bacteria is essential for economic and environmental sustainability. Soil and waste pH. Effects of ammonium and nitrate on mineralization of nitrogen from leguminous residues.

Numbers of nitrite-oxidizing bacteria in the root zone of grassland plants. Moreover, although not taxonomically identified, NB bacterial genera and species were found involved in N cycling and closely related to the genera Nitrosomonas and Nitrosospira, which are reported as abundant in agricultural soils.

Springer, New York, NY. The second approach evaluate microbial functional groups which are involved in N cycling, where functional redundancy is lower, and therefore, any diversity change would have a significant bacterisa on soil processes e.
