Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Organic chemistry

His primary areas of investigation include Soil water, Agronomy, Fertilizer, Environmental chemistry and Plough. His work carried out in the field of Soil water brings together such families of science as Organic matter and Environmental engineering. His studies deal with areas such as Soil organic matter, Loam, Phosphorus and Nitrogen as well as Agronomy.

He focuses mostly in the field of Phosphorus, narrowing it down to topics relating to Biomass and, in certain cases, Park Grass Experiment. While the research belongs to areas of Fertilizer, A. E. Johnston spends his time largely on the problem of Soil biodiversity, intersecting his research to questions surrounding No-till farming and Soil texture. The Environmental chemistry study combines topics in areas such as Pollution and Soil horizon.

His most cited work include:

  • Phosphorus Loss from Soil to Water (343 citations)
  • Optical bistability and signal amplification in a semiconductor crystal: applications of new low‐power nonlinear effects in InSb (252 citations)
  • Long-term Experiments in Agricultural and Ecological Sciences (226 citations)

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

A. E. Johnston focuses on Agronomy, Soil water, Environmental chemistry, Agriculture and Potassium. A. E. Johnston works mostly in the field of Agronomy, limiting it down to topics relating to Soil organic matter and, in certain cases, Soil fertility, as a part of the same area of interest. His Soil water research is multidisciplinary, relying on both Organic matter, Plough, Grassland and Arable land.

A. E. Johnston has included themes like Contamination, Soil contamination and Environmental engineering in his Environmental chemistry study. In his study, Soil management is inextricably linked to Agroforestry, which falls within the broad field of Agriculture. His Fertilizer study combines topics from a wide range of disciplines, such as Loam, Poaceae and Animal science.

He most often published in these fields:

  • Agronomy (48.50%)
  • Soil water (24.81%)
  • Environmental chemistry (16.92%)

What were the highlights of his more recent work (between 2004-2018)?

  • Agronomy (48.50%)
  • Phosphorus (12.03%)
  • Nitrogen (10.15%)

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

His main research concerns Agronomy, Phosphorus, Nitrogen, Potassium and Agroforestry. His Agronomy study incorporates themes from Soil water, Soil fertility and Phosphate. His Soil water research integrates issues from Agroecosystem and Phosphate fertilizer.

The study incorporates disciplines such as Park Grass Experiment, Plant nutrition and Grassland in addition to Phosphorus. His Nitrogen study integrates concerns from other disciplines, such as Soil pH and Crop production. A. E. Johnston combines subjects such as Crop and Soil phosphorus with his study of Fertilizer.

Between 2004 and 2018, his most popular works were:

  • Determinants of Species Richness in the Park Grass Experiment (197 citations)
  • Efficiency of soil and fertilizer phosphorus use. Reconciling changing concepts of soil phosphorus behaviour with agronomic information (189 citations)
  • Testing the distinctness of shoot ionomes of angiosperm families using the Rothamsted Park Grass Continuous Hay Experiment (55 citations)

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

  • Agriculture
  • Ecology
  • Organic chemistry

A. E. Johnston mainly investigates Agronomy, Phosphorus, Fertilizer, Nitrogen and Crop yield. A. E. Johnston works mostly in the field of Phosphorus, limiting it down to concerns involving Park Grass Experiment and, occasionally, Biomass, Species richness and Plant ecology. His research in Fertilizer intersects with topics in Soil structure, Soil water and Loam.

A. E. Johnston specializes in Soil water, namely Soil contamination. His work on Soil nitrogen as part of general Nitrogen study is frequently linked to Production and Dilemma, bridging the gap between disciplines. His Crop yield research includes elements of Agriculture, Winter wheat and Soil fertility.
