Improving nitrogen use efficiency in crop production (eBook)

"Nitrogen is required for food production but most of it is released to the environment where it causes a cascade of negative impacts. This timely book provides an excellent overview of nitrogen use in agriculture and most especially suggestions on how to maximize the benefits of nitrogen while minimizing its detrimental impacts." James N. Galloway, Sidman P. Poole Professor, Emeritus, University of Virginia, USA

In the last 60 years fertiliser use in agriculture has increased by 900%. However, it's been reported that up to 80% of these fertilisers are not utilised by crops but are lost to the environment as nitrous oxide, ammonia and nitrate. Improving nitrogen use efficiency is recognised as one possible solution to reducing the sector's environmental impact and optimising its productivity and sustainability in the face of increasing pressure to feed a growing population.

Improving nitrogen use efficiency in crop production reviews recent advances in understanding nitrogen cycling in soil as well as advances in monitoring nitrogen status and synchronising fertiliser application. The book also considers developments in inorganic fertilisers to improve nitrogen use efficiency, as well as how more organic sources of nitrogen, such as livestock manure, can be optimised to achieve the same goal.

With its comprehensive exploration of nitrogen use efficiency, the book showcases the key role agriculture can play in restoring balance to the global nitrogen cycle.

Featuring contributions from internationally-renowned experts, the book will be a standard reference for researchers in agricultural and environmental science, government and other agencies advising on fertiliser use and its environmental impact, farmers, agronomists, as well as companies manufacturing fertilisers.
