Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]
A pollen core is a core sample of a medium containing a stratigraphic sequence of pollen. Analysis of the type and frequency of the pollen in each layer is used to study changes in climate or land use using regional vegetation as a proxy. [1] [2] This analysis is conceptually comparable to the study of ice cores.
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
At the age of 11 Gunnar made a list of plants at Solvik. Gunnar went to the university and received a doctorate in 1921 with a thesis on pollen studies in German, [3] which made pollen analysis known outside Scandinavia. He studied and worked under Lennart von Post for the study of peat bogs, continuing his work from 1923.
Palynology is an interdisciplinary science that stands at the intersection of earth science (geology or geological science) and biological science , particularly plant science . Biostratigraphy , a branch of paleontology and paleobotany , involves fossil palynomorphs from the Precambrian to the Holocene for their usefulness in the relative ...
Soil morphology is the branch of soil science dedicated to the technical description of soil, [1] particularly physical properties including texture, color, structure, and consistence. Morphological evaluations of soil are typically performed in the field on a soil profile containing multiple horizons .

A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
