Overview

What is he best known for?

The fields of study he is best known for:

Botany
Biochemistry
Agronomy

Agronomy, Botany, Potassium, Chlorosis and Apoplast are his primary areas of study. His work deals with themes such as Plant nutrition, Soil fertility, Bulk soil, Soil pH and Calcareous, which intersect with Agronomy. His study in Plant nutrition is interdisciplinary in nature, drawing from both Biotechnology, Fertilizer and Plant physiology.

His research integrates issues of Soil chemistry and Clay minerals in his study of Fertilizer. His work in the fields of Water stress and Picea abies overlaps with other areas such as Niebla. His research in Potassium intersects with topics in Turgor pressure, Horticulture, Sieve tube element and Osmotic pressure.

His most cited work include:

Principles of plant nutrition (3751 citations)
Iron availability in plant tissues — iron chlorosis on calcareous soils (304 citations)
Soil pH increase due to biological decarboxylation of organic anions (221 citations)

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

His main research concerns Agronomy, Botany, Horticulture, Potassium and Ammonium. Konrad Mengel works mostly in the field of Agronomy, limiting it down to topics relating to Soil pH and, in certain cases, Environmental chemistry and Plant nutrition. In the field of Botany, his study on Chlorosis overlaps with subjects such as Light intensity.

Konrad Mengel works mostly in the field of Horticulture, limiting it down to concerns involving Picea abies and, occasionally, Wax. His Potassium research is multidisciplinary, relying on both Amino acid and Assimilation. The study incorporates disciplines such as Phosphate and Soil horizon in addition to Fertilizer.

He most often published in these fields:

Agronomy (37.80%)
Botany (18.90%)
Horticulture (18.11%)

What were the highlights of his more recent work (between 1997-2009)?

Apoplast (11.02%)
Agronomy (37.80%)
Botany (18.90%)

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

His primary areas of study are Apoplast, Agronomy, Botany, Helianthus annuus and Soil organic matter. His Agronomy study combines topics in areas such as Soil classification, Soil test, Loam and Plant nutrition. His study focuses on the intersection of Plant nutrition and fields such as Calcareous with connections in the field of Soil pH.

His Assimilation study, which is part of a larger body of work in Botany, is frequently linked to Silicic acid, Plant metabolism and Glutamine synthetase, bridging the gap between disciplines. Konrad Mengel usually deals with Helianthus annuus and limits it to topics linked to Chlorosis and Sunflower. The Soil organic matter study combines topics in areas such as Environmental chemistry, Fertilizer, Lolium multiflorum and Animal science.

Between 1997 and 2009, his most popular works were:

The central role of microbial activity for iron acquisition in maize and sunflower. (162 citations)
Apoplastic pH and Fe3+ Reduction in Intact Sunflower Leaves (98 citations)
The paramount influence of nitrate in increasing apoplastic pH of young sunflower leaves to induce Fe deficiency chlorosis, and the re‐greening effect brought about by acidic foliar sprays (55 citations)

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

Botany
Biochemistry
Agronomy

His primary scientific interests are in Agronomy, Apoplast, Chlorosis, Helianthus annuus and Nitrogen cycle. His Agronomy research includes elements of Soil test and Soil horizon. Apoplast is a primary field of his research addressed under Biochemistry.

Konrad Mengel focuses mostly in the field of Chlorosis, narrowing it down to topics relating to Sunflower and, in certain cases, Citric acid, Xylem and Cotransporter. His Nitrogen cycle research integrates issues from Transplanting, Ripening and Loam. His Poaceae research incorporates themes from Sorghum, Shoot and Iron deficiency.
