Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Ecosystem

His main research concerns Agronomy, Leaf area index, Ecology, Nutrient and Biomass. His research integrates issues of Carbon sequestration, Canopy and Ecosystem, Plant litter in his study of Agronomy. His Leaf area index study deals with the bigger picture of Botany.

As a member of one scientific family, Kurt H. Johnsen mostly works in the field of Ecology, focusing on Water content and, on occasion, Vegetation type, Temperate climate and Litter. The Nutrient study combines topics in areas such as Productivity and Soil fertility. His research in Soil fertility intersects with topics in Carbon dioxide, Forest ecology, Carbon cycle and Carbon sink.

His most cited work include:

  • Soil fertility limits carbon sequestration by forest ecosystems in a CO 2 -enriched atmosphere (890 citations)
  • Long term growth responses of loblolly pine to optimal nutrient and water resource availability (220 citations)
  • Re‐assessment of plant carbon dynamics at the Duke free‐air CO2 enrichment site: interactions of atmospheric [CO2] with nitrogen and water availability over stand development (195 citations)

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

His primary areas of investigation include Botany, Agronomy, Loblolly pine, Black spruce and Forestry. His studies in Botany integrate themes in fields like Carbon dioxide, Animal science and Horticulture. He has researched Animal science in several fields, including Nutrient and Growing season.

Kurt H. Johnsen combines subjects such as Ecology, Soil water, Soil respiration and Water content with his study of Agronomy. His study in Forestry is interdisciplinary in nature, drawing from both Carbon sequestration, Agroforestry, Woody plant and Ecosystem. His research in Biomass tackles topics such as Productivity which are related to areas like Leaf area index and Canopy.

He most often published in these fields:

  • Botany (40.59%)
  • Agronomy (33.66%)
  • Loblolly pine (20.79%)

What were the highlights of his more recent work (between 2012-2020)?

  • Agronomy (33.66%)
  • Botany (40.59%)
  • Biomass (18.81%)

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

Kurt H. Johnsen mainly focuses on Agronomy, Botany, Biomass, Ecosystem and Forestry. His work deals with themes such as Soil water, Water content and Loblolly pine, which intersect with Agronomy. The various areas that he examines in his Botany study include Carbon dioxide and Animal science.

His study focuses on the intersection of Biomass and fields such as Basal area with connections in the field of Woody plant. His Ecosystem study introduces a deeper knowledge of Ecology. His Forestry research includes elements of Forest floor, Agroforestry and Understory.

Between 2012 and 2020, his most popular works were:

  • Ecosystem carbon stocks in Pinus palustris forests (36 citations)
  • Spatial and temporal variability of soil CO2 efflux in three proximate temperate forest ecosystems (30 citations)
  • Sustained effects of atmospheric [CO2] and nitrogen availability on forest soil CO2 efflux (20 citations)
