Donald L. Sparks is the S.
His pioneering studies on kinetic processes in soils and minerals include the development of widely used and novel kinetic methods, elucidation of rate-limiting steps and mechanisms over a range of spatial and temporal scales, and coupling of real-time kinetic studies with in-situ molecular scale investigations. His discoveries on the speciation, formation rates and stability mechanisms of metal hydroxide surface precipitates, and their role in the retention and bioavailability of toxic metals in the terrestrial environment, have received worldwide attention.
This research has led to more effective soil remediation strategies and predictive models.
He is the author or coauthor of publications. These include: 11 edited books, 53 book chapters, and refereed papers. Sparks has served as editor of Advances in Agronomy since , having edited 77 volumes. He has given over invited presentations at scientific conferences throughout the world, and been a lecturer at 98 universities and institutes in North America, Europe, Asia, and Australia.
He has received numerous honors and awards including Fellow of five scientific societies, national and international research awards, distinguished fellowships and lectureships, and teaching and mentoring awards.

Published Date: 20th February Page Count: Increased use of organic fertiliser from pig slurry PS , and wastewater sludge WS will lead to the increased environmental occurrence of emerging contaminants, particularly antibiotics and growth hormones.
Environmental transport, fate and exposure must be determined to quantify the development of microbial antibiotic resistance and other environmental and food safety risk, and develop soil and water management practices for risk mitigation. Decreased use of mineral fertilisers and increased use of organic fertilisers will reduce environmental and food safety risks from metals contamination; this is due to lower metal mobility and bioavailability from redox transformations, reduced soil acidification and increased metal complexation on soil organic matter.
Mechanistic soil process models will be tested, further developed to test the specific hypotheses, and applied to quantify process rates that mediate the landscape scale CZ fluxes as a measure of ecosystem service flows.
Earth's critical zone
GIS modelling methods include data from characterisation of a subset of soil properties and process rates at a wider set of locations in the catchment, together with catchment surface water and groundwater monitoring for water and solute flux balances. The GIS model that is developed will identify the geospatial variation in nutrient, contaminant, and GHG sources and sinks and will be used to quantify fluxes at the catchment scale.
These results will determine the current baseline of ecosystem service flows and will evaluate scenarios for how these measures of ecosystem services will change with a transition to widespread of organic fertilisers through the farming area of the catchment.

This project develops a closely integrated project between research teams in the UK and China that directly addresses the following sustainable development challenges of China. Economic development through innovation in agricultural practices 2. Food security through improved agricultural yields on existing productive land 3.
Soil - Wikipedia
Food safety through decreases in plant available soil contaminants 4. Water quality protection and improvement through reduced soil pollution 5. Wellbeing of urban inhabitants through peri-urban land management 6.
Ecological resilience of agricultural production to environmental change 7. Meeting environmental commitments through reduced greenhouse gas emissions from land 8. The environmental impacts of urbanisation The project addresses the challenges effectively by linking the research activities with innovation in farming practices through field manipulation experiments that act as testbeds and demonstrations for the use of organic fertilisers. The project addresses the challenges efficiently by focusing on the role of soil as a central control point within the integrated Critical Zone CZ system where positive changes in managing soil fertility can influence multiple beneficial outcomes to the development challenges.
Efficiency of research investment is gained by drawing on the current investment in staff and infrastructure by the principal China partner IUE at the site and through collaboration with the Zhejiang Academy of Sciences Agricultural Institute in Ningbo city. The programme of impact activities includes strong UK and China stakeholders and performance metrics for immediate and long-term impact are defined.
UK strengths in novel, high throughput molecular tools for soil food web dynamics will be applied with the Chinese investigators at the Ningbo CZO. This will provide the scientific evidence on how in organic fertiliser application will impact the soil N-cycle and can be pro-actively managed to improve yields and long-term soil fertility for food security. UK strengths in novel isotope biogeochemistry will be carried out jointly with the Chinese partners and will provide the scientific evidence to optimise soil management practices that reduce toxic metals uptake to food crops, to improve food safety.
