Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Carbon dioxide

His primary scientific interests are in Agronomy, Nutrient, Soil water, Environmental chemistry and Poaceae. His research integrates issues of Nitrogen fixation, Nitrate and Ammonium in his study of Agronomy. His Nutrient study integrates concerns from other disciplines, such as Biological system and Botany.

The Soil water study combines topics in areas such as Agriculture and Agricultural productivity. His Environmental chemistry research incorporates elements of Organic matter, Soil pH, Phosphorus and Carbon dioxide. His study focuses on the intersection of Poaceae and fields such as Phosphate with connections in the field of Plant physiology, Diffusion, Soil chemistry and Inorganic chemistry.

His most cited work include:

  • Carbon losses from all soils across England and Wales 1978-2003 (902 citations)

  • Soil carbon (10.79%)
  • Soil water (41.73%)
  • Environmental chemistry (19.42%)

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

Guy J. D. Kirk spends much of his time researching Soil carbon, Soil water, Environmental chemistry, Soil organic matter and Biochar. His work deals with themes such as Hydrology, Atmospheric sciences and Field conditions, which intersect with Soil carbon. His studies deal with areas such as Nutrient and Aerenchyma, Agronomy as well as Soil water.

In general Agronomy study, his work on Human fertilization, Fertilizer and Randomized block design often relates to the realm of Brown rice, thereby connecting several areas of interest. His study in the fields of Speciation under the domain of Environmental chemistry overlaps with other disciplines such as Three way. His Soil organic matter research is multidisciplinary, incorporating perspectives in Primary production, Ecosystem, Biogeochemical cycle, Topsoil and Biogeochemistry.

Between 2016 and 2020, his most popular works were:

  • Long-term increases in soil carbon due to ecosystem fertilization by atmospheric nitrogen deposition demonstrated by regional-scale modelling and observations. (37 citations)
  • The greenhouse gas impacts of converting food production in England and Wales to organic methods (35 citations)
  • Experimental determination of zinc isotope fractionation in complexes with the phytosiderophore 2’-deoxymugeneic acid (DMA) and its structural analogues, and implications for plant uptake mechanisms (33 citations)

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

  • Agriculture
  • Ecology
  • Carbon dioxide

Guy J. D. Kirk mainly focuses on Environmental chemistry, Soil water, Soil carbon, Food processing and Organic farming. His Environmental chemistry research incorporates themes from Soil classification, Nitrogen, Acid–base reaction and Carbonic acid. His Soil water study integrates concerns from other disciplines, such as Carbon dioxide, Bicarbonate, Nutrient and Aerenchyma.

His research integrates issues of Primary production, Ecosystem, Biogeochemical cycle, Topsoil and Biogeochemistry in his study of Soil carbon. His research in Organic farming intersects with topics in Environmental impact assessment, Food waste, Food security and Environmental protection. His study in Land use is interdisciplinary in nature, drawing from both Soil carbon sequestration, Agroecology and Greenhouse gas.
