Closing the phosphorus loop in England: The spatio-temporal balance of phosphorus capture from manure versus crop demand for fertiliser

Advances and Perspectives to Improve the Phosphorus Availability in Cropping Systems for Agroecological Phosphorus Management

“…Development of P fertilizer best management practices are beginning to be defined, not only for short-term economic and environmental reasons (i.e., eutrophication of waterways and oligotrophic terrestrial ecosystems) but also for the wise stewardship of the nonrenewable nutrient resources upon which food, feed, fiber, and fuel production depend (Fixen and Johnston, 2012). An important objective is to develop productive farming systems in which P availability in soils is increased, P fertilizer inputs and outputs are reduced, or alternative renewable P resources for crop fertilization (e.g., recycling organic waste from both agroindustry and human communities, manure from intensive animal agriculture, retrieval of P from struvite in sewage) are used (Doyle and Parsons, 2002;Cordell et al, 2011;Simpson et al, 2011;Bateman et al, 2011;Senthilkumar et al, 2012). Strategies dedicated to enhance P use efficiency in farming system were recently reviewed by Simpson et al (2011), , Shen et al (2011), and Veneklaas et al (2012), namely, reduction of P losses (mainly driven by physicochemical soil properties and fertilization practices Hansen et al, 2012)), targeted use of sustainable P fertilizers, effects of cropping system on P recycling, and breeding for plant traits involved in maintaining productivity on low-P soils (Vance, 2010;Lambers et al, 2011).…”

Innovation in Resourcing Geological Materials as Crop Nutrients

“…Although a number of publications report nutrient balances for P and/or N (e.g., Vitousek et al 2009;Bateman et al 2011;MacDonald et al 2011;Dungait et al 2012), very few address K and fewer provide an internally consistent and directly comparable set of data. Consideration of global nutrient balances in the second half of the twentieth century (Sheldrick et al 2002) indicates that K is the nutrient that is being removed most significantly from soils.…”

A review of phosphorus management through the food system: identifying the roadmap to ecological agriculture

“…Thus, these trends posed serious challenges to P management relating with P use efficiency and P security in food system. Bateman et al (2011) indicated management of the agricultural P cycle is therefore the key to achieving the desired agricultural productivity whilst also safeguarding water quality and slowing down consumption of phosphate rock resources. Accordingly there are number of technologies and policy options that together could meet future P management (Gaxiola et al, 2011;Iho and Laukkanen, 2012;Schr€ oder et al, 2011).…”
