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

The scientist’s investigation covers issues in Ecology, Agronomy, Nematode, Botany and Soil biology. Ecology is a component of his Soil food web, Food web, Ecosystem, Trophic level and Abundance studies. His Agronomy research is multidisciplinary, incorporating elements of Soil water, Soil carbon and Soil fertility.

His study looks at the relationship between Nematode and fields such as Organic matter, as well as how they intersect with chemical problems. Howard Ferris combines subjects such as Animal science, Bacterivore and Horticulture, Orchard with his study of Botany. His work investigates the relationship between Soil biology and topics such as Soil organic matter that intersect with problems in Cover crop.

He most often published in these fields:

  • Ecology (36.53%)
  • Agronomy (32.93%)
  • Nematode (26.95%)

  • Soil biodiversity (7.19%)

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

His scientific interests lie mostly in Ecology, Agronomy, Soil biodiversity, Ecosystem and Abundance. Trophic level, Food web, Biomass, Predation and Soil water are the subjects of his Ecology studies. His primary area of study in Agronomy is in the field of Cultivar.

In his study, which falls under the umbrella issue of Ecosystem, Species diversity is strongly linked to Biodiversity. His Soil carbon research integrates issues from Soil organic matter, Soil biology, Soil quality and Bacterivore. His Soil fertility study combines topics in areas such as Cover crop and Soil food web.

Between 2010 and 2021, his most popular works were:

  • Agroecology: A Review from a Global-Change Perspective (163 citations)

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

  • Ecology
  • Agriculture
  • Botany

Howard Ferris mainly investigates Ecology, Soil food web, Agronomy, Soil fertility and Abundance. His Trophic level, Nematode, Soil water and Food web study are his primary interests in Ecology. Soil food web and Soil quality are frequently intertwined in his study.

His Agronomy study integrates concerns from other disciplines, such as Rootstock, Tylenchulus semipenetrans, Mesocriconema xenoplax and Xiphinema index. The various areas that he examines in his Soil fertility study include Soil organic matter and Soil carbon. His studies in Abundance integrate themes in fields like Ecosystem, Ecosystem diversity and Biosphere.
