  • 2001 - Fellow of the American Society of Agronomy (ASA)

Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His primary scientific interests are in Agronomy, Crop, Horticulture, Water use and Canola. His Agronomy study frequently draws connections to other fields, such as Soil water. While the research belongs to areas of Crop, he spends his time largely on the problem of Sowing, intersecting his research to questions surrounding Mean radiant temperature and Temperate climate.

When carried out as part of a general Horticulture research project, his work on Brassica is frequently linked to work in Growth inhibition and Take-all, therefore connecting diverse disciplines of study. His research investigates the link between Water use and topics such as Pasture that cross with problems in Yield, Crop yield, Plant breeding and Legume. His work deals with themes such as Plant physiology, Glucosinolate and Allelopathy, which intersect with Canola.

His most cited work include:

  • 'Haying-off', the negative grain yield response of dryland wheat to nitrogen fertiliser. I. Biomass, grain yield, and water use (254 citations)
  • Biofumigation: Isothiocyanates released from Brassica roots inhibit growth of the take-all fungus (253 citations)
  • Increasing Water Use and Water Use Efficiency in Dryland Wheat (223 citations)

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

John Angus mostly deals with Agronomy, Crop, Soil water, Canola and Sowing. The Agronomy study combines topics in areas such as Plant nutrition and Horticulture. His research integrates issues of Dry matter, Biomass, Poaceae, Yield and Grazing in his study of Crop.

His Soil water research is multidisciplinary, incorporating elements of Tillage, Growing season and Water content. His Canola study combines topics in areas such as Brassica, Fertilizer and Salinity. His research investigates the connection between Sowing and topics such as Mineralization that intersect with issues in Soil test and Nitrogen cycle.

He most often published in these fields:

  • Agronomy (106.17%)
  • Crop (43.21%)
  • Soil water (28.40%)

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

  • Agronomy (106.17%)
  • Crop (43.21%)
  • Canola (27.16%)

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

The scientist’s investigation covers issues in Agronomy, Crop, Canola, Agroforestry and Pasture. The Anthesis research he does as part of his general Agronomy study is frequently linked to other disciplines of science, such as Mathematics, therefore creating a link between diverse domains of science. The concepts of his Anthesis study are interwoven with issues in photoperiodism and Sowing.

His Crop research is multidisciplinary, incorporating perspectives in Biomass and Grazing. His Canola study combines topics from a wide range of disciplines, such as Salinity, Yield and Subsoil. John Angus combines subjects such as Water use and Crop yield with his study of Pasture.

Between 2010 and 2021, his most popular works were:

  • Break crops and rotations for wheat (139 citations)
  • Break crops and rotations for wheat (139 citations)
  • Diversity and Evolution of Rainfed Farming Systems in Southern Australia (42 citations)

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

  • Agriculture
  • Ecology
  • Agronomy

His main research concerns Pasture, Agronomy, Agroforestry, Water use and Crop. His work deals with themes such as Intensive farming, Soil water, Crop yield, Nitrogen balance and Arid, which intersect with Pasture. His studies deal with areas such as Canola, Legume, Yield and Plant breeding as well as Crop yield.

Agronomy is frequently linked to Dryland farming in his study. His Agroforestry research incorporates elements of Ruminant, Plant nutrition, Animal nutrition, Animal breeding and Grazing.
