1. Strategic nitrogen management in stockless organic cropping systems : redistribution of residual biomass for improved energy and nitrogen balance
Abstract : Agriculture faces the challenge of producing high yields to feed a growing world population, while simultaneously addressing environmental problems such as eutrophication, emissions of greenhouse gases, loss of biodiversity and soil degradation. Organic farming can be part of the solution, as it promotes biodiversity, uses less energy for fertiliser production and often has higher inputs of organic matter to soil than conventional farming.

3. Modeling the Potential for Carbon Removal in Agriculture: Integrating Farmer Perspectives
Abstract : The overarching aim of this thesis is to provide insights into the dynamic processes governing SOC stocks and to identify viable paths for agricultural systems to contribute to climate change mitigation. By integrating current scientific knowledge of carbon sequestration in agriculture with feasible agricultural applications, this work proposes local realistic strategies for enhancing soil organic carbon (SOC) and presents a quantitative assessment of their potential for CO2 removal.

4. Understanding crop and farm management : links to farm characteristics, productivity, biodiversity, marketing channels and perceptions of climate change
Abstract : Agriculture faces challenges in meeting rising demand for food, feed, fibre and fuel while coping with pressure from globalisation, limited natural resources and climate change. Farmers will choose management practices based on their goals and available resources and these practices will influence farm performance. READ MORE
