His Hydrology study combines topics from a wide range of disciplines, such as Nitrification, Amazon rainforest, Cedrela odorata, Denitrification and Nitrate.

Tim H.E. Heaton focuses mostly in the field of Ecology, narrowing it down to topics relating to Atmospheric sciences and, in certain cases, Fagus sylvatica, Water-use efficiency and Rainforest. His Agriculture research includes themes of Crop and Herding. His δ15N research incorporates themes from Isotopes of nitrogen and Inorganic nitrogen.

Between 2010 and 2020, his most popular works were:

  • Crop manuring and intensive land management by Europe’s first farmers (261 citations)
  • Manuring and stable nitrogen isotope ratios in cereals and pulses: towards a new archaeobotanical approach to the inference of land use and dietary practices (217 citations)
  • Assessing natural variation and the effects of charring, burial and pre-treatment on the stable carbon and nitrogen isotope values of archaeobotanical cereals and pulses (76 citations)

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

  • Ecology
  • Agriculture
  • Ecosystem

The scientist’s investigation covers issues in Agronomy, Agriculture, Crop, Ecology and Environmental chemistry. Tim H.E. Heaton combines subjects such as Period, δ15N and Isotopes of carbon with his study of Agronomy. His δ15N research is multidisciplinary, relying on both Arid and Isotopes of nitrogen.

His work in Agriculture addresses issues such as Agroforestry, which are connected to fields such as Animal husbandry, Herbivore, Range, Land use and Manure. His work deals with themes such as Isotope analysis and Nitrate, which intersect with Environmental chemistry. His work in Nitrate covers topics such as Deposition which are related to areas like Ecosystem.
