Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His primary areas of investigation include Agronomy, Leaching, Nitrification, Soil water and Pasture. His Agronomy study incorporates themes from Loam, Ammonium and Nitrogen. Keith C. Cameron interconnects Enzymatic hydrolysis, Lysimeter, Nitrate and Soil horizon in the investigation of issues within Leaching.

His research investigates the link between Nitrification and topics such as Nitrogen cycle that cross with problems in Archaea. His Soil water study combines topics in areas such as Nitrous oxide and Fertilizer. The concepts of his Pasture study are interwoven with issues in Cover crop, Irrigation and Arable land.

His most cited work include:

  • Nitrate leaching in temperate agroecosystems: sources, factors and mitigating strategies (735 citations)
  • Nitrification driven by bacteria and not archaea in nitrogen-rich grassland soils (603 citations)
  • Nitrogen losses from the soil/plant system: a review (525 citations)

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

His primary areas of study are Agronomy, Leaching, Soil water, Pasture and Lysimeter. His Agronomy research is multidisciplinary, relying on both Nitrate, Loam and Nitrification, Nitrogen. While the research belongs to areas of Nitrification, Keith C. Cameron spends his time largely on the problem of Nitrous oxide, intersecting his research to questions surrounding Greenhouse gas.

His Leaching research is multidisciplinary, relying on both Fertilizer, Irrigation, Effluent, Denitrification and Animal science. His Soil water research incorporates themes from Environmental chemistry and Water content. His Pasture research includes themes of Urea, Dry matter, Lolium perenne and Trifolium repens.

He most often published in these fields:

  • Agronomy (57.25%)
  • Leaching (37.65%)
  • Soil water (32.16%)

What were the highlights of his more recent work (between 2016-2021)?

  • Agronomy (57.25%)
  • Leaching (37.65%)
  • Nitrogen (22.35%)

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

Keith C. Cameron mainly investigates Agronomy, Leaching, Nitrogen, Pasture and Animal science. His Agronomy study which covers Soil water that intersects with Nitrification. His research integrates issues of Lolium multiflorum, Irrigation, Soil nitrogen, Lysimeter and Nitrate in his study of Leaching.

His study looks at the relationship between Nitrogen and fields such as Environmental chemistry, as well as how they intersect with chemical problems. Keith C. Cameron has included themes like Nitrous oxide and Fertilizer in his Pasture study. The various areas that he examines in his Animal science study include Agriculture, Urine nitrogen, Grazing and Effluent.

Between 2016 and 2021, his most popular works were:

  • A review of plant options for mitigating nitrous oxide emissions from pasture-based systems (19 citations)
  • Nitrate leaching losses are lower from ryegrass/white clover forages containing plantain than from ryegrass/white clover forages under different irrigation (17 citations)
  • Potential inhibition of urine patch nitrous oxide emissions by Plantago lanceolata and its metabolite aucubin (14 citations)

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

  • Agriculture
  • Ecology
  • Nitrogen

Keith C. Cameron mostly deals with Agronomy, Leaching, Nitrogen, Lysimeter and Irrigation. His Agronomy study combines topics from a wide range of disciplines, such as Nitrous oxide, Soil water and Nitrification. His Nitrification research incorporates elements of Contamination and Archaea.

Keith C. Cameron combines subjects such as Lolium multiflorum, Nitrate, Grazing and Trifolium repens with his study of Leaching. His Nitrogen research focuses on Ammonia and how it connects with Liquid manure, Methane, Environmental chemistry, Ammoniacal nitrogen and Dissolved organic carbon. His Lysimeter study combines topics in areas such as Cow urine, Pore size, Nitrate leaching and Drainage.
