Legacy Nutrient Management and Remediation in Diverse Agricultural Watersheds
… impairments persist due to the accumulation of legacy nutrients—phosphorus (P) stored in soils and nitrogen (N) stored in groundwater—that continue to be mobilized long after management changes are implemented. This dissertation evaluates the magnitude, persistence, uncertainty, and mitigation …

Preservation and Deployment of Biofertilizers to Mitigate Soil Phosphorous Loss from Agricultural Systems
The world is approaching peak phosphorus within the next 20 years, which poses a severe threat to the food security of a rapidly growing global population. Phosphorus is the second most essential macronutrient for plants after nitrogen, and its scarcity results in stunted growth, poor root …

Phosphorus fate and management on the Somerset Levels and Moors Ramsar ditch systems
Fundamental to all life, phosphorus is an essential nutrient and, contrastingly, a significant threat to surface water biodiversity globally as one of the most common causes of eutrophication in surface waters worldwide. Freshwater wetland ditches afflicted by these conditions undergo a shift from …

An investigation of the biogeochemical exchange of the macro plant nutrients phosphorus and nitrogen on rewetted peat soil on the Somerset Levels and Moors.
Phosphorus, an essential nutrient for life, excess phosphorus is a common ecological concern in watercourses worldwide leading to eutrophication and pollution of natural water systems. In the UK, eutrophication of freshwater systems is one of the most common cause of water bodies not achieving good …
