Research.com Recognitions

  • 2026 - Research.com Environmental Sciences in United States Leader Award
  • 2015 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Agriculture
  • Ecosystem

G. P. Robertson spends much of his time researching Agronomy, Ecology, Soil carbon, Cycling and Nutrient. The Agronomy study combines topics in areas such as Soil organic matter, Agriculture and Deciduous. Many of his research projects under Ecology are closely connected to Tropical and subtropical coniferous forests with Tropical and subtropical coniferous forests, tying the diverse disciplines of science together.

His Soil biodiversity research integrates issues from Soil biology and Soil morphology. His Soil carbon study integrates concerns from other disciplines, such as Global warming, Greenhouse effect, Carbon cycle and Carbon sequestration. His work on Nutrient cycle as part of his general Nutrient study is frequently connected to Materials science and Macropore, thereby bridging the divide between different branches of science.

His most cited work include:

  • Greenhouse gases in intensive agriculture: contributions of individual gases to the radiative forcing of the atmosphere. (1111 citations)
  • Standard soil methods for long-term ecological research (1029 citations)
  • Nutrient Imbalances in agricultural development (830 citations)

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

His primary areas of study are Agronomy, Agriculture, Ecology, Soil carbon and Soil science. His Agronomy research is multidisciplinary, relying on both No-till farming and Soil water. His work carried out in the field of Agriculture brings together such families of science as Agroforestry, Ecosystem services, Nitrous oxide, Greenhouse gas and Sustainability.

His study on Greenhouse gas also encompasses disciplines like

  • Global warming, which have a strong connection to Fertilizer,
  • Methane that intertwine with fields like Carbon dioxide. His research integrates issues of Plant community, Monoculture and Carbon cycle in his study of Soil carbon. He usually deals with Soil biodiversity and limits it to topics linked to Soil biology and Soil morphology.

He most often published in these fields:

  • Agronomy (46.00%)
  • Agriculture (24.00%)
  • Ecology (19.00%)

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

  • Soil carbon (21.00%)
  • Climate change (11.00%)
  • Agronomy (46.00%)

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

Soil carbon, Climate change, Agronomy, Nitrous oxide and Monoculture are his primary areas of study. His Soil carbon research incorporates elements of Cover crop, No-till farming, Cropping system and Bioenergy. G. P. Robertson performs multidisciplinary study on Agronomy and Water-use efficiency in his works.

The concepts of his Nitrous oxide study are interwoven with issues in Perennial plant, Grassland ecosystem, Crop and Greenhouse gas. His Greenhouse gas study also includes fields such as

  • Global warming and related Agriculture,
  • Microcosm together with Soil water. G. P. Robertson works mostly in the field of Monoculture, limiting it down to concerns involving Plant community and, occasionally, Biomass, Carbon cycle, Soil chemistry and Soil microbiology.

Between 2016 and 2021, his most popular works were:

  • Hotspots of soil N 2 O emission enhanced through water absorption by plant residue (56 citations)
  • Microbial spatial footprint as a driver of soil carbon stabilization. (41 citations)
  • Microbial spatial footprint as a driver of soil carbon stabilization. (41 citations)

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

  • Ecology
  • Agriculture
  • Ecosystem

G. P. Robertson mostly deals with Soil science, Agriculture, Nitrous oxide, Greenhouse gas and Monoculture. His Agriculture research incorporates themes from Sustainability and Ecosystem services. The study incorporates disciplines such as Global warming, Climate change, Fertilizer and Environmental engineering in addition to Nitrous oxide.

The study incorporates disciplines such as Denitrification, Soil water, Bulk soil and Absorption of water in addition to Greenhouse gas. His Monoculture study combines topics in areas such as Plant community, Soil chemistry, Carbon cycle and Soil microbiology. His Soil microbiology research incorporates elements of Biomass and Soil carbon.
