  • 2011 - Fellow of the American Society of Agronomy (ASA)

Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Agronomy
  • Ecology

His primary areas of investigation include Agronomy, Tillage, Fertilizer, Sowing and Plough. His study in Agronomy is interdisciplinary in nature, drawing from both Loam and Nutrient. He focuses mostly in the field of Tillage, narrowing it down to topics relating to Surface runoff and, in certain cases, Erosion, Stover, Soil water and Infiltration.

The concepts of his Sowing study are interwoven with issues in Soil management, Crotalaria and Green manure. His work deals with themes such as No-till farming and Chisel, which intersect with Plough. Charles S. Wortmann has included themes like Soil nitrate and Phaseolus in his Crop study.

His most cited work include:

  • Atlas of common bean (Phaseolus vulgaris L.) production in Africa (196 citations)
  • Tillage and Rotation Interactions for Corn and Soybean Grain Yield as Affected by Precipitation and Air Temperature (144 citations)
  • Nutrient balances and expected effects of alternative practices in farming systems of Uganda (137 citations)

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

His primary scientific interests are in Agronomy, Fertilizer, Nutrient, Manure and Sorghum. In his research, Mucuna is intimately related to Soil fertility, which falls under the overarching field of Agronomy. His biological study spans a wide range of topics, including Soil organic matter, Agriculture, Grain yield and Agroforestry.

The various areas that he examines in his Nutrient study include Phaseolus and Soil test. In his study, Soil water, Loam, Erosion and Water quality is inextricably linked to Surface runoff, which falls within the broad field of Manure. The study incorporates disciplines such as Soil management and Sowing in addition to Sorghum.

He most often published in these fields:

  • Agronomy (67.36%)
  • Fertilizer (29.02%)
  • Nutrient (26.94%)

What were the highlights of his more recent work (between 2017-2021)?

  • Agronomy (67.36%)
  • Fertilizer (29.02%)
  • Nutrient (26.94%)

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

Charles S. Wortmann mostly deals with Agronomy, Fertilizer, Nutrient, Crop and Agriculture. Charles S. Wortmann is interested in Sorghum, which is a branch of Agronomy. His Fertilizer research incorporates elements of Grain yield, Yield, Manure and Yield.

He combines subjects such as Vigna and Soil water with his study of Nutrient. His work in Crop tackles topics such as Legume which are related to areas like Soil management. His Agriculture study incorporates themes from Enteric disease and Agricultural science.

Between 2017 and 2021, his most popular works were:

  • Soybean response to nitrogen application across the United States: A synthesis-analysis (36 citations)
  • Does occasional tillage undo the ecosystem services gained with no-till? A review (28 citations)
  • Tetracycline and Sulfonamide Antibiotic Resistance Genes in Soils From Nebraska Organic Farming Operations. (20 citations)

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

  • Agriculture
  • Agronomy
  • Ecology

His main research concerns Agronomy, Nutrient, Fertilizer, Soil test and Crop. His Crop yield study, which is part of a larger body of work in Agronomy, is frequently linked to Yield, bridging the gap between disciplines. His Nutrient research incorporates themes from Yield and Abiotic component.

In his study, which falls under the umbrella issue of Fertilizer, Grain yield is strongly linked to Yield. His Crop research includes themes of Legume and Fodder. His studies in Fodder integrate themes in fields like Pennisetum, Sorghum, Stover, Manure and Productivity.
