What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Surface runoff

His primary scientific interests are in Surface runoff, Hydrology, Eutrophication, Soil water and Manure. His Surface runoff research is multidisciplinary, incorporating perspectives in Environmental engineering, Agronomy, Water pollution, Water quality and Erosion. His work carried out in the field of Hydrology brings together such families of science as Soil type and Nutrient.

His Eutrophication study incorporates themes from Agriculture and Environmental protection. Andrew N. Sharpley focuses mostly in the field of Soil water, narrowing it down to topics relating to Animal science and, in certain cases, Crop, Dissolution, Diammonium phosphate and Soil pH. The various areas that Andrew N. Sharpley examines in his Manure study include Fertilizer, Leaching and Distilled water.

His most cited work include:

  • Managing Agricultural Phosphorus for Protection of Surface Waters: Issues and Options (1196 citations)
  • Relating Extractable Soil Phosphorus to Phosphorus Losses in Runoff (645 citations)

What are the main themes of his work throughout his whole career to date?

Andrew N. Sharpley spends much of his time researching Surface runoff, Hydrology, Soil water, Water quality and Agriculture. His work deals with themes such as Environmental engineering, Agronomy, Manure, Erosion and Eutrophication, which intersect with Surface runoff. Hydrology is frequently linked to Nutrient in his study.

Within one scientific family, Andrew N. Sharpley focuses on topics pertaining to Environmental chemistry under Soil water, and may sometimes address concerns connected to Sorption. His research integrates issues of Nutrient management, Tillage, Watershed management and Water resource management in his study of Water quality. His study in Agriculture is interdisciplinary in nature, drawing from both Environmental planning, Environmental resource management and Environmental protection.

He most often published in these fields:

  • Surface runoff (42.82%)
  • Hydrology (33.06%)
  • Soil water (30.35%)

What were the highlights of his more recent work (between 2015-2020)?

  • Agriculture (22.76%)
  • Surface runoff (42.82%)
  • Water quality (29.54%)

In recent papers he was focusing on the following fields of study:

Andrew N. Sharpley mainly investigates Agriculture, Surface runoff, Water quality, Hydrology and Watershed. The concepts of his Agriculture study are interwoven with issues in Environmental planning, Environmental resource management, Natural resource economics, Manure and Sustainability. His Surface runoff study combines topics from a wide range of disciplines, such as Fertilizer, Tillage, Nutrient management, Nutrient and Land management.

His Fertilizer research incorporates themes from Soil water and Animal science. His Water quality research is multidisciplinary, incorporating elements of Leaching, Environmental protection, Agricultural productivity, Eutrophication and Wetland. Andrew N. Sharpley works mostly in the field of Eutrophication, limiting it down to concerns involving Agronomy and, occasionally, Regosol.

Between 2015 and 2020, his most popular works were:

  • Long-term accumulation and transport of anthropogenic phosphorus in three river basins (148 citations)
  • Increased soluble phosphorus loads to Lake Erie:unintended consequences of conservation practices? (121 citations)
  • Integrating legacy soil phosphorus into sustainable nutrient management strategies for future food, bioenergy and water security (113 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Ecosystem

The scientist’s investigation covers issues in Agriculture, Water quality, Surface runoff, Eutrophication and Hydrology. His Agriculture research is multidisciplinary, relying on both Agricultural engineering, Natural resource economics, Environmental resource management and Environmental planning. His Nonpoint source pollution study in the realm of Water quality connects with subjects such as Saturation ratio.

The Surface runoff study combines topics in areas such as Soil classification, Soil science, Soil water, Agronomy and Nutrient management. His Eutrophication research incorporates themes from Surface water, Drainage basin, Manure, Sewage treatment and Biogeochemistry. Andrew N. Sharpley combines subjects such as Ecology and Sewage with his study of Hydrology.
