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.
