Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Ecosystem

Murray Unkovich spends much of his time researching Agronomy, Nitrogen fixation, Legume, Pasture and Agriculture. He regularly ties together related areas like Crop residue in his Agronomy studies. The concepts of his Nitrogen fixation study are interwoven with issues in Ecosystem, Nitrogen cycle, Botany and Nitrogen assimilation.

His research integrates issues of Lupinus angustifolius, Nitrogen deficiency and Plant roots in his study of Legume. His study in Pasture is interdisciplinary in nature, drawing from both Plant nutrition and Annual plant. His Agriculture research includes elements of Enzyme assay, Water use, Soil water, Carbon accounting and Nitrogenase.

His most cited work include:

  • An appraisal of recent field measurements of symbiotic N2 fixation by annual legumes (305 citations)
  • Measuring plant-associated nitrogen fixation in agricultural systems (279 citations)
  • Potential precision of the δ15N natural abundance method in field estimates of nitrogen fixation by crop and pasture legumes in south-west Australia (155 citations)

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

Agronomy, Nitrogen fixation, Crop, Pasture and Plant nutrition are his primary areas of study. His work carried out in the field of Agronomy brings together such families of science as Soil water and Crop residue. His study looks at the relationship between Nitrogen fixation and fields such as Botany, as well as how they intersect with chemical problems.

The Crop study combines topics in areas such as Fertilizer, Dry matter, Irrigation, Agriculture and Yield. His work deals with themes such as Grazing, Growing season and Annual plant, which intersect with Pasture. Murray Unkovich has researched Legume in several fields, including Field pea and Shoot.

He most often published in these fields:

  • Agronomy (60.78%)
  • Nitrogen fixation (21.57%)
  • Crop (19.61%)

What were the highlights of his more recent work (between 2010-2021)?

  • Agronomy (60.78%)
  • Crop (19.61%)
  • Cropping (8.82%)

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

His primary areas of study are Agronomy, Crop, Cropping, Agriculture and Nitrogen fixation. His work is dedicated to discovering how Agronomy, Plant nutrition are connected with Water use and other disciplines. In his study, which falls under the umbrella issue of Crop, Leaf area index is strongly linked to Yield.

His Agriculture research is multidisciplinary, incorporating perspectives in Agroforestry and Medicago sativa. The various areas that Murray Unkovich examines in his Nitrogen fixation study include Isotope fractionation, Botany and Soil nitrogen. His Dry matter study incorporates themes from Growing region, Nitrogen cycle, Shoot and Nitrate, Nitrate reductase.

Between 2010 and 2021, his most popular works were:

  • Methodologies for estimating nitrogen transfer between legumes and companion species in agro-ecosystems: A review of 15N-enriched techniques (56 citations)
  • Interactions between water and nitrogen in Australian cropping systems: physiological, agronomic, economic, breeding and modelling perspectives (54 citations)
  • Isotope discrimination provides new insight into biological nitrogen fixation (51 citations)

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

  • Agriculture
  • Ecology
  • Ecosystem

Murray Unkovich mainly focuses on Agronomy, Ecosystem, Legume, Nitrogen fixation and Water use. He combines subjects such as Abundance, 15n isotope, Fractionation and Pruning with his study of Ecosystem. Legume is closely attributed to Forage in his study.

His Nitrogen fixation study combines topics in areas such as Soil water, Isotope fractionation and Botany. His studies in Water use integrate themes in fields like Biomass, Plant nutrition and Yield gap. His Plant nutrition research is multidisciplinary, incorporating elements of Grazing, Soil pH and Pasture.
