His primary areas of study are Agronomy, Root hair, Diffusion, Plant physiology and Soil water. His work on Shoot, Root growth and Phosphorite as part of general Agronomy study is frequently connected to Diffusion and Pulp and paper industry, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. His Root hair research includes elements of Plant species and Horticulture.
His work carried out in the field of Horticulture brings together such families of science as Poaceae, Lolium perenne and Chenopodiaceae. His Plant physiology study necessitates a more in-depth grasp of Botany. His studies deal with areas such as Stereochemistry and Phosphate as well as Soil water.
His primary scientific interests are in Agronomy, Horticulture, Soil water, Shoot and Botany. Norbert Claassen focuses mostly in the field of Agronomy, narrowing it down to topics relating to Loam and, in certain cases, Bulk soil. The Horticulture study combines topics in areas such as Plant species and Spinach.
The various areas that Norbert Claassen examines in his Soil water study include Fertilizer, Sowing, Plant physiology, Crop yield and Phosphate. His research investigates the connection between Shoot and topics such as Cultivar that intersect with problems in Root growth. His Hordeum vulgare and Shoot dry weight study, which is part of a larger body of work in Botany, is frequently linked to Phosphatase, bridging the gap between disciplines.
His main research concerns Agronomy, Soil water, Horticulture, Sunflower and Sugar beet. Norbert Claassen has researched Agronomy in several fields, including Loam and Soil solution. His research integrates issues of Coprecipitation, Fraction, Environmental chemistry and Citramalic acid in his study of Soil water.
His Sunflower research is multidisciplinary, relying on both Shoot and Spinach. Shoot is the subject of his research, which falls under Botany. Norbert Claassen integrates many fields, such as Sugar beet and Root hair, in his works.
Norbert Claassen mostly deals with Agronomy, Sugar beet, Shoot, Horticulture and Soil water. His Agronomy research is multidisciplinary, incorporating elements of Plant nutrition, Phosphorus concentration, Bulk density, Soil pH and Soil temperature. The study incorporates disciplines such as Cluster root, Poaceae, Chenopodiaceae and Citramalic acid in addition to Sugar beet.
Shoot is a subfield of Botany that Norbert Claassen tackles. The concepts of his Horticulture study are interwoven with issues in Salicylic acid, Soil phosphorus, Solubilization and Spinach.
