Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Carbon dioxide
  • Ecosystem

Agronomy, Soil water, Denitrification, Intercropping and Environmental chemistry are his primary areas of study. Cropping system is the focus of his Agronomy research. His research in Soil water intersects with topics in Fertilizer and Grassland.

His work carried out in the field of Denitrification brings together such families of science as Soil type, Nitrification, Ecosystem, Nitrogen cycle and Greenhouse gas. His biological study spans a wide range of topics, including Nitrogen fixation, Crop yield, Crop and Hordeum vulgare. His Environmental chemistry study incorporates themes from Pyrolysis and Biochar.

His most cited work include:

  • Atmospheric composition change: Ecosystems–Atmosphere interactions (434 citations)
  • Full accounting of the greenhouse gas (CO2, N2O, CH4) budget of nine European grassland sites (372 citations)
  • INTERSPECIFIC COMPETITION, N USE AND INTERFERENCE WITH WEEDS IN PEA-BARLEY INTERCROPPING (351 citations)

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

The scientist’s investigation covers issues in Agronomy, Environmental chemistry, Soil water, Ecosystem and Ecology. His research integrates issues of Crop residue and Nitrogen in his study of Agronomy. As a part of the same scientific family, he mostly works in the field of Environmental chemistry, focusing on Nitrous oxide and, on occasion, Atmospheric sciences.

Per Ambus focuses mostly in the field of Soil water, narrowing it down to matters related to Denitrification and, in some cases, Nitrification. His research investigates the connection with Ecosystem and areas like Nitrogen cycle which intersect with concerns in Mineralization. His Hordeum vulgare study integrates concerns from other disciplines, such as Sativum and Field pea.

He most often published in these fields:

  • Agronomy (33.86%)
  • Environmental chemistry (23.11%)
  • Soil water (20.72%)

What were the highlights of his more recent work (between 2015-2021)?

  • Agronomy (33.86%)
  • Ecosystem (15.94%)
  • Soil carbon (8.37%)

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

His scientific interests lie mostly in Agronomy, Ecosystem, Soil carbon, Environmental chemistry and Soil water. His research on Agronomy frequently connects to adjacent areas such as Biochar. His Ecosystem research also works with subjects such as

  • Global warming which connect with Soil respiration, Terrestrial ecosystem, Field experiment and Sucrose,
  • Climate change together with Cycling, Atmospheric sciences and NOx.

The concepts of his Environmental chemistry study are interwoven with issues in Nitrous oxide, Carbon pool and Nitrogen deficiency, Nitrogen. His Soil water research integrates issues from Temperate climate, Spectrometer, δ13C, Nitrogen cycle and Nutrient. Per Ambus works mostly in the field of Nitrogen cycle, limiting it down to topics relating to Nitrification and, in certain cases, Botany, as a part of the same area of interest.

Between 2015 and 2021, his most popular works were:

  • How does biochar influence soil N cycle? A meta-analysis (73 citations)
  • Productivity and carbon footprint of perennial grass–forage legume intercropping strategies with high or low nitrogen fertilizer input (41 citations)
  • Productivity and carbon footprint of perennial grass–forage legume intercropping strategies with high or low nitrogen fertilizer input (41 citations)

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

  • Ecology
  • Carbon dioxide
  • Agriculture

The scientist’s investigation covers issues in Agronomy, Ecosystem, Environmental chemistry, Soil carbon and Crop yield. His research integrates issues of Biochar, Temperate climate and Nitrogen in his study of Agronomy. His Ecosystem study results in a more complete grasp of Ecology.

Environmental chemistry is closely attributed to Animal science in his research. His Soil carbon study incorporates themes from Wetland, Greenhouse gas, Carbon sink and Slash-and-char. The Soil water study combines topics in areas such as Nutrient cycle, Denitrification and Nitrogen cycle.
