The National Agricultural Nitrous Oxide Research Program (NANORP) was a national research network of 23 projects under an agreed collaborative program that has developed and delivered effective and practical strategies for reducing nitrous oxide emissions while maintaining crop and pasture productivity.
Automated greenhouse gas sampling systems with in situ gas analysis were deployed at 15 sites

The NANORP was principally funded by the Australian Government Department of Agriculture, Fisheries and Forestry (now Agriculture and Water Resources) with a AUD20M investment over 4 years (2012-2016) and was preceded by the Nitrous Oxide Research Program (2009-2012). An additional AUD30M was provided through industry, state, university and CSIRO investments.
The NANORP was managed by the Grains Research and Development Corporation (GRDC). The program coordination and scientific leadership of NANORP was provided by the Institute for Future Environments, Queensland University of Technology (QUT).
The first phase of NANORP (2012-2015) collected 234 complete datasets from 50 studies to develop effective nitrogen management strategies to increase agricultural productivity and reduce N2O emissions and associated losses.
The network is a member of Coherence in Information for Agricultural Research for Development (CIARD) – an initiative to make agricultural research information more publicly available and accessible. The network supports the CIARD manifesto and complies with its checklist for disseminating agricultural research data.

For growers
Greenhouse gas emissions and farming practices
Nitrous oxide (N2O) gas is emitted naturally from the microbial processes of nitrification and denitrification in the soil. The use of nitrogenous fertilisers, and the return of animal dung and urine, in agricultural activities increases the soil content in mineral nitrogen. In turn, this increases the rate at which bacteria release N2O. The figure below summarises the soil nitrogen cycle.

How N2O is emitted in the atmosphere
Along with carbon dioxide and methane, N2O is a powerful greenhouse gas (GHG). Increased worldwide GHG emissions due to human activity can intensify the greenhouse effect which leads to climate change. In Australia, agriculture is the dominant human source of the greenhouse gases N2O and methane1. The table below shows the main on-farm sources of GHGs.
{insert table here}
Increased N2O emissions have harmful long-term effects in the lower and upper atmosphere. Unusually high levels of N2O emissions also indicate fertiliser overuse and lead to ecological damage from the leaching of nitrates into groundwater or by entering the water systems of other ecological systems as runoff.
Reducing on-farm N2O emissions
Farmers can adopt a range of N2O management techniques to reduce emissions from agricultural soils. For example, by changing the timing, type and amount of nitrogenous fertiliser applied to the soil; using nitrification inhibitors and cover crops; adopting sustainable tillage systems; and improving irrigation practices and good manure and soil management. These management practices might be the basis for a future national strategy to reduce GHG emissions from agricultural soils.
N2O research can help by identifying optimal fertiliser application regimes; ones that will maximise yields whilst minimising emissions. By applying nitrogenous fertilisers more efficiently, farming can also become less resource-intensive and lower its costs through the reduced use of fertiliser. This also improves the ecological footprint of farming activities by reducing gas emissions and minimising the harmful effects of nitrogenous fertilisers.
N2O research and the N2O Network
Further research is still needed to determine how to best reduce N2O emissions. The complex interactions between all three major GHGs as well as the soil properties unique to each crop need to be taken into account when studying N2O emissions.
Emissions research has traditionally mainly focussed on carbon dioxide and research data on N2O soil emissions from Australian soils is still limited. The N2O Network is the first effort to bring together researchers who measure and model N2O emissions for dryland and irrigated farming (particularly grains, cotton, sugarcane and dairy) from sites around Australia.
The N2O Network will provide the latest available scientific knowledge on reducing N2O soil emissions in the form of tools and advice to farmers, consulting agronomists, extension officers and policy makers. The N2O Network will also help researchers standardise their datasets and collection methods to produce more powerful simulations of emissions for various land-use types and climatic conditions.
A central database of N2O research will be made available by the network to the wider GHG research community for further analysis and interpretation.

Understanding nitrous oxide emissions from agriculture and principles for mitigation
This document presents the current state of knowledge relating to the processes responsible for nitrous oxide production and emission from agricultural soils. That knowledge is then used to develop some general principles that should be considered in managing specific agricultural production systems. The aim has been to produce a technical resource for farmers and service providers, especially those in the fertiliser industry, who provide advice and guidance to farmer managers.
For Researchers
Rationale for an N2O research data repository
By collating a large diverse set of data in one place, the portal will ensure the best solutions can be provided for reducing N2O emissions whilst sustaining the productivity of farming systems.
Access to a larger data pool will also raise the prospect of calibrating and validating models that rely on the synthesis of greenhouse gas emissions data.
The standardised methods implemented by the network are essential to making evidence-based policy on climate change mitigation more robust.
The repository plays a significant role in ensuring the science behind agricultural N2O soil emissions in Australia more robust, as well as more open to scrutiny and use by the international community.
The N2O emissions data repository
One objective of the N2O Network is to create a data portal that aggregates N2O (and other non-CO2 gases) and makes it available to the wider climate change community.
The repository creates a conduit to share and access research data from the various N2O sites in the network. The repository will serve all the data using standard data formats and data sharing protocols.

The flow of research data in the N2O Network
Datasets stored in the repository contains detailed descriptions of relevant data the collection methods. Research data will be readily available for download in a standard file format and in compliance with a data protocol.
A set of terms and conditions governs how research data can be used and shared. An authentication system limits data access to accredited users only. By agreeing to the terms and conditions, these accredited users gain the authority to immediately access the data.
Community-driven standards and protocols
The IT platform underlying the data portal is KNB Metacat. Metacat is a community-driven data repository that was specifically developed to store ecological research data. It has a built-in web interface to search and download ecological data. Metacat has been successfully deployed at a number of ecological research sites around the world.
Data stored in Metacat will comply with an N2O data protocol that is largely based on those of ICASA (International Consortium for Agricultural Systems Applications) standards. The protocol specifies data collection methods, the parameters required for each dataset and what additional descriptions (metadata) are expected.
Ecologists interact with Metacat by using Morpho. Morpho is a software assistant to add critical metadata to research data collection and annotate datasets. It also helps track new versions of the data and to upload the latest version of the datasets to the repository.
N2O Metadata Standard
The N2O Metadata Standard has been developed by network researchers as a guide to preparing data for upload to the N2O repository. It is available in N2O data protocol.
For Policy Makers
Why focus on N2O from agriculture?
N2O is a powerful GHG. It is 296 times more potent than carbon dioxide (CO2) and stays in the atmosphere for up to 114 years. As the residual amounts of chlorofluorocarbons (CFCs) and other ozone-depleting gases disappear in the stratosphere, N2O is increasingly becoming the main contributor to thinning stratospheric ozone. This ozone helps protects Earth from harmful UV radiation. In the lower atmosphere, N2O is a precursor to tropospheric ozone which is both a pollutant and yet another GHG.
So, even though far less N2O is emitted than CO2, its potency and longevity makes it an important agent in climate change. Yet, to date, research and policy has primarily focussed on CO2emissions, with attention to N2O emissions lagging behind. Soil scientists and farm advisors are calling for short-term management plans to control N2O emissions and long-term policies to reduce emissions.
The Garnaut Climate Change Review recommends committing resources to overcome gaps in nitrous oxide (N2O) emissions data so that they will be available to greenhouse gases (GHG) accounting and potentially for use in an emissions trading scheme. In Australia, the agricultural sector contributes 16.3% of Australia‘s total GHG emissions. This percentage is significantly high compared to many other developed nations; for example, agriculture both in the US and UK only contributes about 7% of total GHG emissions. This suggests that, in Australia,agriculture has a greater role to play in reducing GHG emissions.
Mitigating N2O represents a real and significant opportunity to reduce the greenhouse effect from anthropogenic emissions from agriculture. In 2007, Australian N2O emissions from agricultural soils were estimated at 20.2 million tonnes of “carbon dioxide equivalent” or 85.9% of all anthropogenic N2O emissions. Between 1990 and 2007, N2O emissions in Australia rose by 24%1 and this increase is largely attributable to the increased application of nitrogenous fertilisers.
An evidence-based, long-term policy on GHG emissions will address the long-term sustainability of agriculture in Australia, while improving land management practices. This can significantly reduce on-farm N2O emissions in the short term and lead to positive flow-on effects such as improving farming productivity and profitability.
Better access to research data and analysis of N2O emissions from Australian soils is a necessary first step for a comprehensive evidence-based national policy on gas emissions. Likewise, this access to research data will help the Australian farming community devise better land-use management.
The diagram below outlines the basic processes by which the Network‘s initial field measurements and observations are transformed into meaningful simulations and projections for policy makers implementing action for environmental change.

How N2O emissions science informs policy and action
Contributing to evidence-based policy
The N2O Network is the first national effort to bring together N2O emissions research data for agricultural soils from around Australia. Funding the N2O Network reflects the commitment of the Grains Research Development Corporation to investigate the effects of climate change-causing (GHGs) on Australia and how they can be best managed.
The network encompasses a number of research programs that collect N2O soil emissions data and analyse how local conditions contribute to the increase in emissions from farming practices. The N2O Network brings these programs together to create a comprehensive picture of N2O emissions across Australia. For the first time, emissions data from a range of climatic conditions, farming methods and crops are made available and accessible to researchers from a single source.
Meaningful Impact
New research resulting from data collected by the N2O Network will provide advice, trends and projections on N2O emissions that will:
- enable better policymaking for decreasing on-farm GHG emissions by quantifying agricultural gas emissions and how to manage them
- contribute to the National Carbon Accounting System – Department of Climate Change and Energy Efficiency – by estimating GHG emissions from managed land systems
- contribute to Australia‘s National Greenhouse Gas Inventory2
- reinforce the role of farmers as front-line participants in action to mitigate GHG emissions and climate change.

Fact sheets
Industry factsheets
Significant reductions in N2O emissions from agriculture can only be achieved through education of key concepts and on-the-ground implementation of key strategies. The dissemination and extension of information to industry has been facilitated through the development of industry specific factsheets. These factsheets provide growers and agronomists the best available information for reducing N2O emissions through the sustainable management of their crops and pastures.
Fertcare factsheets
Fertcare is a joint program between Fertilizer Australia and the Australian fertilizer Services Association. Its role is to improve the skills and knowledge of anyone involved in the supply of fertilizer and soil ameliorant products. It ensures that high quality advice is passed on to farmers, allowing them to optimise productivity while minimising environment and food safety risks. Factsheets for reducing N2O emissions from a variety of agricultural industries have also been developed in consultation with Fertcare.
