Biological nitrogen fixation (BNF) refers to a microbial mediated process based upon an
enzymatic “Nitrogenase” conversion of atmospheric nitrogen (N2) into ammonium readily …

The demand for nitrogen (N) for crop production increased rapidly from the middle of the
twentieth century and is predicted to at least double by 2050 to satisfy the on-going …

Cobalt is a transition metal located in the fourth row of the periodic table and is a neighbor of
iron and nickel. It has been considered an essential element for prokaryotes, human beings …

Industrially produced N-fertilizer is essential to the production of cereals that supports
current and projected human populations. We constructed a top-down global N budget for …

A review has been undertaken into how soil organic matter (SOM) affects a range of soil
properties that are important for the productive capacity of soils. The potential effect of …

Biological dinitrogen (N 2) fixation is a natural process of significant importance in world
agriculture. The demand for accurate determinations of global inputs of biologically-fixed …

Although diazotrophs are important in the nitrogen (N)-cycle and contribute to the pool of
plant available N, the population response to long-term inorganic fertilization is largely …

The amount of reactive N in soils on the Australian continent appears to be increasing,
mainly because of biological N-fixation by permanent pastures in the dryland farming zone …

Microbial community diversity and structure, which underpin soil function, can in turn be
impacted by land-use practices. In this study an agricultural site with consistent long term (+ …

Microbial ecologists continue to seek a greater understanding of the factors that govern the
ecological significance of microbial community structure. Changes in community structure …
