Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Agriculture

His primary scientific interests are in Mycorrhiza, Botany, Mycelium, Biochemistry and Metabolism. There are a combination of areas like Glomus, Agronomy, Nutrient, Species richness and No-till farming integrated together with his Mycorrhiza study. His work carried out in the field of Agronomy brings together such families of science as Soil biology and Soil management.

David D. Douds has researched Botany in several fields, including Species diversity and Manure. While working on this project, David D. Douds studies both Mycelium and Arbuscular mycorrhiza. In general Biochemistry, his work in Glycogen and Carbohydrate is often linked to Pentose phosphate pathway linking many areas of study.

His most cited work include:

  • Environmental, Energetic, and Economic Comparisons of Organic and Conventional Farming Systems (914 citations)
  • Nitrogen transfer in the arbuscular mycorrhizal symbiosis (680 citations)
  • Arbuscular mycorrhizas : physiology and function (315 citations)

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

David D. Douds spends much of his time researching Botany, Mycorrhiza, Agronomy, Fungus and Spore. Hypha, Daucus carota, Exudate, Mycelium and Hyphal growth are the primary areas of interest in his Botany study. His Germ tube study in the realm of Hypha connects with subjects such as Branching.

A majority of his Mycorrhiza research is a blend of other scientific areas, such as Glomus, Phycomycetes, Metabolism, Biochemistry and Trehalose. When carried out as part of a general Agronomy research project, his work on Compost is frequently linked to work in No-till farming, therefore connecting diverse disciplines of study. His Fungus research is multidisciplinary, incorporating elements of Host and Crop.

He most often published in these fields:

  • Botany (48.10%)
  • Mycorrhiza (43.04%)
  • Agronomy (37.97%)

What were the highlights of his more recent work (between 2011-2019)?

  • Agronomy (37.97%)
  • Inoculation (20.25%)
  • Fungus (29.11%)

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

His main research concerns Agronomy, Inoculation, Fungus, Colonization and Horticulture. His Agronomy research includes elements of Propagule, Nutrient and Agriculture. The Propagule study combines topics in areas such as Spore and Drought tolerance.

His biological study spans a wide range of topics, including Tectona, Shoot and Sowing. As part of one scientific family, David D. Douds deals mainly with the area of Fungus, narrowing it down to issues related to the Crop, and often Arbuscular mycorrhizal fungi, Host and Brassicaceae. Botany covers David D. Douds research in Cultivar.

Between 2011 and 2019, his most popular works were:

  • Fall cover cropping can increase arbuscular mycorrhizae in soils supporting intensive agricultural production (78 citations)
  • Utilization of inoculum of AM fungi produced on-farm for the production of Capsicum annuum: A summary of seven years of field trials on a conventional vegetable farm (16 citations)
  • Pelletized Biochar as a Carrier for AM Fungi in the On-Farm System of Inoculum Production in Compost and Vermiculite Mixtures (13 citations)

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

  • Botany
  • Ecology
  • Fungus

The scientist’s investigation covers issues in Agronomy, Fungus, Colonization, Allium porrum and Inoculation. His work in the fields of Agronomy, such as Drought tolerance, overlaps with other areas such as No-till farming. His research ties Compost and Fungus together.

His study deals with a combination of Colonization and Biochar. His Inoculation research incorporates themes from Greenhouse, Yield, Pepper and Cultivar. His Propagule research is multidisciplinary, relying on both Biomass, Paspalum notatum, Cover crop and Tillage.
