Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Agriculture
  • Ecosystem

Alec D. Mackay mainly focuses on Agronomy, Pasture, Soil water, Fertilizer and Soil organic matter. Many of his studies on Agronomy involve topics that are commonly interrelated, such as Loam. His Pasture study deals with the bigger picture of Ecology.

His work carried out in the field of Soil water brings together such families of science as Trampling and Water content. His Soil organic matter research includes elements of Soil test, Soil fertility and Animal science. His Soil management research includes themes of Ecosystem services, Natural capital and Environmental resource management.

His most cited work include:

  • A framework for classifying and quantifying the natural capital and ecosystem services of soils (516 citations)
  • Soil temperature effects on root growth and phosphorus uptake by corn (118 citations)
  • Earthworms and rate of breakdown of soybean and maize residues in soil (113 citations)

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

The scientist’s investigation covers issues in Agronomy, Pasture, Soil water, Soil organic matter and Grazing. His study in Agronomy is interdisciplinary in nature, drawing from both Soil carbon, Nutrient and Soil fertility. His research investigates the link between Pasture and topics such as Agroforestry that cross with problems in Ecosystem services, Agriculture and Soil conservation.

His research integrates issues of Organic matter, Trampling and Water content in his study of Soil water. His Soil organic matter study combines topics from a wide range of disciplines, such as Soil classification and Leaching. His Grazing research is multidisciplinary, incorporating elements of Livestock, Stocking and Greenhouse gas.

He most often published in these fields:

  • Agronomy (52.31%)
  • Pasture (37.69%)
  • Soil water (26.15%)

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

  • Ecosystem services (13.85%)
  • Agronomy (52.31%)
  • Grazing (16.92%)

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

Alec D. Mackay mostly deals with Ecosystem services, Agronomy, Grazing, Soil water and Soil carbon. His Ecosystem services study combines topics in areas such as Natural resource, Biodiversity, Environmental resource management and Farm planning. Alec D. Mackay does research in Agronomy, focusing on Pasture specifically.

His Grazing research integrates issues from Stocking and Greenhouse gas. His work investigates the relationship between Soil water and topics such as Earthworm that intersect with problems in Mesocosm. His Soil carbon research incorporates elements of Forestry, Soil phosphorus and Soil horizon.

Between 2016 and 2021, his most popular works were:

  • Managing Natural Capital Stocks for the Provision of Ecosystem Services (42 citations)
  • Unpacking systemic innovation capacity as strategic ambidexterity: How projects dynamically configure capabilities for agricultural innovation (24 citations)
  • Influence of earthworm abundance and diversity on soil structure and the implications for soil services throughout the season (17 citations)

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

  • Ecology
  • Agriculture
  • Ecosystem

His primary scientific interests are in Ecosystem services, Land use, Land management, Environmental resource management and Biodiversity. Alec D. Mackay works in the field of Ecosystem services, focusing on Natural capital in particular. His studies deal with areas such as Riparian zone and Sustainable development as well as Land use.

In Land management, Alec D. Mackay works on issues like Natural resource management, which are connected to Ecosystem health, Ecosystem valuation and Ecosystem management. His work deals with themes such as Agroforestry, Habitat, Externality, Bank and Sustainability, which intersect with Biodiversity. The study incorporates disciplines such as Profitability index, Natural resource, Agriculture and Ecosystem in addition to Natural resource economics.
