Abstract

UK-China Virtual Joint Centre for Improved Nitrogen Agronomy (CINAG)

Despite making great progress, China still needs to increase agricultural production to feed its growing population with its increasing expectations while overcoming the considerable environmental problems that industrial and agricultural development has brought with it such as air and water pollution and soil acidification. Currently the three main cereal crops (wheat, maize and rice) use only 33% of the nitrogen fertiliser applied, and less than 40% of the nutrients in recyclable organic 'wastes' such as livestock manure are returned to agriculture. China Agricultural University (CAU), the Chinese Academy of Agricultural Sciences (CAAS) and the Chinese Academy of Sciences (CAS) have developed innovative and successful ways of working with farmers to improve the situation, increasing yields of winter wheat and summer maize by 35% and reducing nitrogen fertiliser use by 20%. However, the Chinese Government has set the goal of increasing yields with zero increases in chemical inputs by the year 2020.

Rothamsted Research and its partners in this proposal, the Centre for Ecology and Hydrology (CEH) and Bangor University (BU), have worked with CAU, CAAS and CAS for over 10 years, producing research into agriculture and the environment that has been published in the very best journals such as 'Nature' and 'Science' but also used by Chinese farmers through such mechanisms as a Chinese fertiliser recommendations system and farmer field schools. We propose to increase our UK-China collaborative research through a Virtual Joint Centre in Nitrogen Agronomy that would:
1. Carry out joint research projects, in particular using novel 'Farm Platforms' that will allow us to develop economically and environmentally sustainable farm systems through research at the farm level.
2. Exchange staff and students for laboratory and field work, with a strong focus on UK-to-China movements and for periods of 1-3 months, e.g. summer student visits from the UK to China to work on the new CAU Cropping Farm Platform.
3. Hold joint conferences and meetings, with public participation.
4. Share data management, publications and practical work with farmers in China and the UK.
We will develop novel metagenomic-based indicators of N use efficiency and soil quality, use these indicators, and other emerging knowledge, to test and develop farm systems that permit the sustainable intensification of (especially Chinese) agriculture, and take these developments to Chinese farmers. We will achieve this through four Work Packages: improved fundamental understanding of N cycling; harnessing novel N technologies; improved agronomic practices; predictive capacity and knowledge exchange

The Centre will build on previous collaborations such as China Partnering Awards and joint projects between the partners such as 'Sino-United Kingdom Low Carbon Agriculture' project (Grant FCO-C02/62.1001), 2008-2011, funded jointly by the UK FCO and the Chinese Ministry of Agriculture and an existing VJC with CAAS: The 'Centre for the Sustainable Intensification of Agriculture' (CSIA) and closely link to similar international initiatives such as EU 'N Expert Panel', utilising the Panel's approaches for expressing NUE at (1) the farm level and (2) through the food chain in order to compare systems and regions and as a stimulus to use N more efficiently.

The Centre will translate its research into practice in China through the existing and very 'Science and Technology Backyard (STB)' programme, managed by our partners at CAU, CAAS and the Hebei Institute of Agricultural Sciences, and linked to Chinese local government extension agencies, fertiliser companies and farmers.

Planned Impact

The Chinese government has set the goal for researchers of increasing agricultural output but with zero increase in chemical inputs, especially of N fertiliser, after 2020. This is a major challenge, requiring the reconfiguration of Chinese agriculture over the next 10 years. The UK and other developed countries need a step change in how they improve and monitor N use efficiency and soil quality in general. We can now identify key steps in N cycling and mineralisation using standard enzymatic assays, and use these together with soil metagenomes that determine the phylogenetic diversity of key genes as measures of soil functional health (including the expression level of key genes involved in C and N cycling). We propose to apply these methods to the quantitative assessment of N cycling and general soil quality and health in China and the UK, delivering a novel molecular diagnostic test for soil N supply. This would take methods of measuring soil quality to a new level and facilitate maximising N use in cropping systems.

We will carry out preliminary tests of manure metagenomics to see if this can inform on nutrient content and better N use efficiency from manures. We will develop recommendation tables for organic amendments, especially manures, for China's Fertiliser Recommendations and a CrapApp (see http://www.swarmhub.co.uk/about.php?id=3919 ) for China. We will develop next-generation monitoring schemes with key indicators developed from Sustainable Intensification metrics and current work with the Sustainable Development Solutions Network such as the 'Indicators and a Monitoring Framework for Sustainable Development Goals'.

The research focus will be provided by using complementary farm platforms in the UK and China, linked to research on other farm platforms around the world via the Global Farm Platforms programme (GFP). In particular, CAU will be establishing a new arable platform on an existing 500-ha university farm 70 km south of Bejing. Together we will design and develop an innovation and demonstration farm for China: the CAU Farm Platform (CAUFP). The farm will test and compare economically, agronomically, environmentally and socially sustainable farm businesses and be a model for the whole of China and be the focus of joint research that will include UK staff and students working on the CAUFP. Translation will be primarily through the continuing very successful socioeconomic and agronomic integrated science of the 'Science and Technology Backyard (STB)' programme, managed by our partners at CAU in collaboration with the Crop Science Group at CAAS and the Hebei Institute of Agricultural Sciences, and linked to Chinese local government extension agencies, fertiliser companies and farmers.

The VJC will help address poverty issues for Chinese farmers by providing solutions relating to the environmental and economic sustainability of food production in China. Proven, internationally-excellent, research groups from the UK and China will collaborate to improve Nitrogen Use Efficiency across a range of cropping systems, and dedicated capacity building, research translation and outreach activities will ensure direct economic and social benefits to farmers across the country. Through an increase in the skills and knowledge base of Chinese agricultural researchers the VJC will further improve China's ability to undertake and disseminate research to maximise impact on the issues of rural and economic growth through the sustainable intensification of agriculture. Furthermore, there will be significant development of research infrastructures for the agriculture, food security and environmental protection sectors; all of which have been identified as priorities by the Chinese government for welfare enhancement and economic development.

Description A modelling study conducted by members of the CINAg team and reported in the journal Environmental Science and Technology (Vol 50, pages 13409-13418) illustrates how optimising use of manure nutrients in the range of livestock production systems in China could reduce N, P and K fertiliser input by up to 27, 82 and 100% by 2020 if barriers to recycling manure nutrients can be overcome.

Improved knowledge of inorganic fertilizer and manure effects on soil health and ecosystem services: manure significantly changes soil biological and chemical properties while traditional fertilizer management has biggest effect on soil structure; manure application is a means to increase soil organic carbon and can substitute inorganic fertilizers, thus helping to realize the goals for global 0.4% soil carbon increase and zero inorganic fertilizer increase in the intensively managed agriculture on the North China Plain.

A novel set of potential soil health indicators for different soil types (for the UK, but for further assessment and development for China).

Improved knowledge/recommendations on practices and application rates for specific cropping rotations and regions (particularly the North China Plain), based on experimental results and extensive scenario modelling that will enable reductions in fertilizer N use with no reductions in crop yield, directly contributing to meeting China's zero increase in fertilizer policy.

Improved knowledge on the use of urease and nitrification inhibitors with N fertilizers and manures to improve crop N use efficiency, and of the factors influencing their effectiveness; this knowledge can be used for development of improved fertilizer products and tailored recommendations regarding their use.

Demonstration of the potential for acidification (with sulphuric acid) of digestates from anaerobic digestion of food-waste, crop and livestock manure-based feedstocks to greatly reduce N losses via ammonia volatilization and improve digestate N use efficiency following application to arable crops.

Improved quantification of N losses through different parts of the manure management chain for China livestock production systems


A framework for a decision support tool for manure nutrient use in China (MANNER-China; together with the N-Circle project)

Academic outputs include >80 joint publications in peer-reviewed journals (with more in preparation and submission), numerous international conference and workshop presentations, and several published datasets.
Exploitation Route These findings have implications for future nitrogen fertilizer use and particularly manure management in China. Options regarding optimal nutrient use can be developed as guidance for farmers and inform policy direction and actions. The development of nutrient management plans to fully account for manure nutrients will be environmentally beneficial (fewer nutrient losses to the wider environment), but only economically beneficial if previous fertilizer industry subsidies are redirected to improve manure management practices. To improve manure utilization, large changes and investments in the livestock farm infrastructure, namely, animal housing, manure storage, and facilities for manure transportation and application, are needed. An integrated manure and fertilizer nutrient recommendation system has to be developed that takes account of the total nutrient and available nutrient contents of manures. Finally, the resulting improved knowledge needs to be disseminated to farmers.

Title Greenhouse gas emissions, nitrogen use efficiency and biomass from digestate experiments on winter wheat at North Wyke and Henfaes, UK (2017) 
Description The data contains nitrogen (N) offtake, N emissions (ammonia and nitrous oxide), soil parameters (pH, EC, NH4+, NO3-), biomass and grain production from a winter wheat field experiment located at Bangor University (Henfaes Research Station in North Wales) and Rothamsted Research (North Wyke (NW) in Devon). Data were collected between April 2017 and August 2017. Measurements and soil and plant samples were taken from 45 plots in a randomized complete block design. Sixteen extra mini-plots at the prevailing wind (south westerly) edge of the experiment site were used at NW for NH3 volatilization measurements. The treatments were control (C, without N application), food based digestate (D), food based digestate + the nitrification inhibitor 3,4-dimethylpyrazole (DMPP; D+NI), acidified food based digestate (AD), acidified food based digestate + the nitrification inhibitor 3,4-dimethylpyrazole (DMPP; AD+NI). Four rates of ammonium nitrate (NH4NO3; 75, 150, 225 and 300 kg N ha-1) were applied to compare yields and fertilizer replacement rate of the digestate treatments (targeted at 190 kg N ha-1). Soil pH, soil electrical conductivity (EC), soil NH4+ and soil NO3-, NH3 volatilization, N2O emissions were measured periodically for C, D, D+NI, AD and AD+NI and nitrogen concentration in grain and straw, grain yield and plant biomass for all treatments. Nitrogen offtake, losses and fluxes were used to determine the N use efficiency (NUE) and fertilizer replacement rate of the digestate treatments. Measurements were undertaken by members of staff from Bangor University, School of Environment, Natural Resources & Geography and Rothamsted Research, Sustainable Agricultural Sciences - North Wyke. Data was collected for the Newton Fund project "UK-China Virtual Joint Centre for Improved Nitrogen Agronomy".

Title Greenhouse gas emissions, nitrogen use efficiency and biomass from inorganic fertiliser additions to grassland at North Wyke and Henfaes, UK (2016) 
Description The data consists of nitrogen (N) offtake, N emissions and soil N parameters, and herbage quality parameters from a three-cut silage plot trial located at two grassland sites within the UK collected between April and October 2016. The sites were Rothamsted Research at North Wyke in Devon and Bangor University at Henfaes Research Station in North Wales. At each site measurements were taken from 16 plots, organised within a randomised complete block design. Fertiliser was applied three times and three cuts were performed, all parameters measured were following a fertiliser application. Nitrogen parameters measured were crude protein (CP) of herbage, ammonia (NH3) emissions, nitrous oxide (N2O) emissions, and soil ammonium (NH4) and nitrate (NO3). Herbage quality parameters measured were dry matter, acid-digestible fibre (ADF), ash, CP, metabolizable energy (ME), and non-digestible fibre (NDF) and digestibility (D) was calculated. Nitrogen offtake, losses and fluxes were measured to determine the N use efficiency and the economic viability of different N fertilisers.

Title Nitrous oxide emission factors of mineral fertilisers in the UK and Ireland (1999-2019) 
Description Data from 38 experimental sites across the UK and Ireland were collated resulting in 623 separate mineral fertiliser N2O emission factors (EF) estimates derived from field measurements. Data were either i) extracted from published studies in which one aim of the experimentation was to explicitly measure N2O and report EFs after a mineral fertiliser application, or ii) raw data were used from the Agricultural and Environmental Data Archive (AEDA). To find the published data, a survey of literature was conducted using Google Scholar for articles considered 'recent' (20 years or fewer), i.e. published after January 1998 and submitted before April 2019. The following search terms and their variations were used: N2O, nitrous oxide, emission factor, mineral fertiliser, ammonium nitrate, urea, nitrification inhibitor, nitrogen use efficiency, agriculture, greenhouse gas, grassland and arable. This search based on keywords was complemented with a search through the literature cited in the articles found and known previous research.
