The Indian Nitrogen Assessment: Sources of Reactive Nitrogen, Environmental and Climate Effects, and Management Options and Policies provides a reference for anyone interested in Reactive N, from researchers and students, to environmental managers. Although the main processes that affect the N cycle are well known, this book is focused on the causes and effects of disruption in the N cycle, specifically in India. The book helps readers gain a precise understanding of the scale of nitrogen use, misuse, and release through various agricultural, industrial, vehicular, and other activities, also including discussions on its contribution to the pollution of water and air. Drawing upon the collective work of the Indian Nitrogen Group, this reference book helps solve the challenges associated with providing reliable estimates of nitrogen transfers within different ecosystems, also presenting the next steps that should be taken in the development of balanced, cost-effective, and feasible strategies to reduce the amount of reactive nitrogen.
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 and best practices to assess crop nitrogen status, such as the use of proximal sensors and remote sensing techniques. The book considers developments in the use of inorganic nitrogen fertilisers and their effectiveness in optimising nitrogen use efficiency, as well as how more organic sources of nitrogen, such as livestock manure, can be optimised to achieve the same goal.
