Overview

What is he best known for?

The fields of study he is best known for:

  • Agronomy
  • Agriculture
  • Ecology

George W. Clayton mainly investigates Agronomy, Tillage, Cultivar, Crop rotation and Conventional tillage. Canola, Field pea, Crop, Weed and Green manure are subfields of Agronomy in which his conducts study. His Weed research incorporates elements of Weed control and Crop yield.

His study explores the link between Tillage and topics such as Mulch-till that cross with problems in Crop production, Strip-till, Water erosion and Minimum tillage. His research in Cultivar intersects with topics in Grain yield, Poaceae and Seeding. His study looks at the relationship between Conventional tillage and topics such as No-till farming, which overlap with Red Clover, Soil structure and Soil management.

His most cited work include:

  • Soil microbial diversity and community structure under wheat as influenced by tillage and crop rotation (382 citations)
  • Cattle Manure Amendments Can Increase the pH of Acid Soils (298 citations)
  • Pulse Crop Adaptation in the Northern Great Plains (207 citations)

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

His primary scientific interests are in Agronomy, Canola, Cultivar, Weed and No-till farming. Agronomy is represented through his Hordeum vulgare, Tillage, Crop, Field pea and Seeding research. George W. Clayton focuses mostly in the field of Tillage, narrowing it down to topics relating to Crop rotation and, in certain cases, Rhizosphere.

His Canola study integrates concerns from other disciplines, such as Fertilizer, Soil water, Brassica, Brassica rapa and Glyphosate. George W. Clayton works mostly in the field of Weed, limiting it down to topics relating to Weed control and, in certain cases, Cropping and Agroforestry. His No-till farming research includes themes of Soil management and Cropping system.

He most often published in these fields:

  • Agronomy (91.77%)
  • Canola (43.04%)
  • Cultivar (24.05%)

What were the highlights of his more recent work (between 2009-2016)?

  • Agronomy (91.77%)
  • Canola (43.04%)
  • Hordeum vulgare (21.52%)

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

The scientist’s investigation covers issues in Agronomy, Canola, Hordeum vulgare, Cultivar and No-till farming. Weed, Fertilizer, Seeding, Crop yield and Weed control are among the areas of Agronomy where the researcher is concentrating his efforts. His Fertilizer research is multidisciplinary, incorporating perspectives in Soil biology, Crop rotation and Tillage.

George W. Clayton combines subjects such as Coated urea and Intercropping with his study of Canola. He interconnects Sativum, Field pea and Grain yield in the investigation of issues within Hordeum vulgare. George W. Clayton usually deals with No-till farming and limits it to topics linked to Cropping system and Growing season, Soil management and Agroforestry.

Between 2009 and 2016, his most popular works were:

  • Crop yield and nitrogen concentration with controlled release urea and split applications of nitrogen as compared to non-coated urea applied at seeding (118 citations)
  • Weed-Competitive Ability of Spring and Winter Cereals in the Northern Great Plains (64 citations)
  • Seeding Rate, Nitrogen Rate, and Cultivar Effects on Malting Barley Production (51 citations)

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

  • Agriculture
  • Agronomy
  • Ecology

His primary areas of study are Agronomy, Cultivar, Hordeum vulgare, Fertilizer and Canola. His work is connected to Weed, Crop yield, Yield, Tillage and Weed control, as a part of Agronomy. His work in the fields of Tillage, such as Conventional tillage, overlaps with other areas such as Cru.

His research in Weed control tackles topics such as Biomass which are related to areas like Crop rotation. His work deals with themes such as Soil biology and No-till farming, which intersect with Hordeum vulgare. The various areas that George W. Clayton examines in his No-till farming study include Soil management, Cropping system and Bulk soil.
