Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

Peter Millard mainly investigates Botany, Ecology, Agronomy, Soil water and Cycling. His Botany research integrates issues from Seasonality and Horticulture. His Horticulture research is multidisciplinary, relying on both Biomass, Acclimatization and RuBisCO.

His research in Agronomy intersects with topics in Soil fertility, Mineralization, Soil organic matter, Woody plant and Rhizosphere. His research integrates issues of Climate change, Community structure and Microbial population biology in his study of Soil water. His Cycling research is multidisciplinary, incorporating elements of Dry matter, Nutrient, Deciduous and Nitrogen balance.

His most cited work include:

  • Unravelling rhizosphere–microbial interactions: opportunities and limitations (331 citations)
  • Assessing shifts in microbial community structure across a range of grasslands of differing management intensity using CLPP, PLFA and community DNA techniques (325 citations)
  • Nitrogen storage and remobilization by trees: ecophysiological relevance in a changing world (297 citations)

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

His primary areas of study are Botany, Agronomy, Horticulture, Shoot and Soil water. His Agronomy research is multidisciplinary, relying on both Rhizosphere, Nutrient and Cycling. His work deals with themes such as Soil pH, Microcosm and Microbial population biology, which intersect with Rhizosphere.

Peter Millard has researched Horticulture in several fields, including Urea, Perennial plant, Plant physiology and Transpiration. His studies deal with areas such as Rootstock, Plant nutrition, Herbivore, Betula pubescens and Juglans as well as Shoot. Soil science and Ecology are all intrinsically tied to his study in Soil water.

He most often published in these fields:

  • Botany (39.31%)
  • Agronomy (36.99%)
  • Horticulture (27.17%)

What were the highlights of his more recent work (between 2008-2021)?

  • Agronomy (36.99%)
  • Soil water (14.45%)
  • Rhizosphere (12.72%)

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

Peter Millard mainly investigates Agronomy, Soil water, Rhizosphere, Soil respiration and Soil organic matter. The concepts of his Agronomy study are interwoven with issues in Photosynthesis and Nutrient. The subject of his Soil water research is within the realm of Ecology.

His work carried out in the field of Rhizosphere brings together such families of science as Biomass, Soil pH and Botany. Peter Millard works in the field of Botany, namely Shoot. He interconnects Environmental chemistry and Soil carbon in the investigation of issues within Soil respiration.

Between 2008 and 2021, his most popular works were:

  • Nitrogen storage and remobilization by trees: ecophysiological relevance in a changing world (297 citations)
  • Methane, microbes and models: fundamental understanding of the soil methane cycle for future predictions (176 citations)
  • Does carbon storage limit tree growth (154 citations)

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

  • Ecology
  • Botany
  • Ecosystem

Soil water, Agronomy, Soil respiration, Ecology and Soil carbon are his primary areas of study. His biological study spans a wide range of topics, including Reforestation and Botany. Environmental factor is the focus of his Botany research.

His research in Agronomy intersects with topics in Woody plant and Soil fertility. His Soil respiration research includes themes of Nutrient and Horticulture. His work in the fields of Climate change, Biogeochemical cycle, Greenhouse gas and Soil biodiversity overlaps with other areas such as Land use, land-use change and forestry.
