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 …

Because nitrogen is one of the major elements limiting growth of plants in agrosystems,
large amounts of N fertilisers have been used in the second half of the twentieth century …

The second edition of this book, first published in 1991 and intended for students and
researchers, contains revised and updated material on the theory and practice of nitrogen …

This book shows scientists how to apply their analysis and synthesis skills to overcoming the
challenge of how to write, as well as what to write, to maximise their chances of publishing in …

Background Humans in various cultures have feared snakes, provoking an aversion and
persecution that hinders conservation efforts for these reptiles. Such fact suggests that …

In this paper we review both the methods for estimating N2 fixation and the quantity of N2
fixed by annual crop legumes. Available data on the N difference method for estimating N2 …

Abstract The Intergovernmental Panel on Climate Change (IPCC) standard methodology to
conduct national inventories of soil N 2 O emissions is based on default (or Tier I) emission …

In the last 40 years, the global use of mineral N fertilizers has increased to support
increasing food demand. Misuse of fertilizer has led to environmental problems in some …

Legumes play a crucial role in nitrogen supply to grass-legume mixtures for ruminant fodder.
To quantify N transfer from legumes to neighbouring plants in multi-species grasslands we …

The objective of the present review was to present the current knowledge on nitrogen (N)
rhizodeposition, including techniques for 15N labelling of agricultural plants, amounts of N …
