Journal of Soil Science, 1961
Summary Acidic soils (pH below 5.5) may contain a great deal of pollen through the profile, and the floristic composition of this pollen may vary greatly in samples from successively greater depths. Various attempts have been made in the past to interpret pollen diagrams from soils, but they have usually broken down ...

This book describes latest analytical procedures of key soil health indicators including physical, chemical and biological parameters. Most of the Soil Analysis manuals currently available, primarily deal with basic chemical and physical properties without giving emphasis on soil health assessment. However, literature shows indicator parameters such as

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1990
Determinations of constituents present in soils and soil solutions at trace concentrations are conducted primarily because of interest in soil as a medium for plant growth or because of its influence upon the solute chemistry of fresh waters and ground waters.

Proceedings of the Prehistoric Society, 1982
Samples for pollen analysis were cut from freshly cleaned excavation sections. They were taken at one or two centimetre intervals through the buried soils and the reave bank. Towards the top of each section samples were taken at five centimetre intervals.The position of each of the sample columns taken is recorded on the drawn sections in the ...

International Conference on Military Technologies (ICMT) 2015, 2015
The mobility is one from the most important factor during military operations. Soils cover most of the Earth's surface, therefore the military planners rely heavily on soil analysis. With regard to cross-country movement (CCM), we differentiate individual types and sorts of soils.

Physicochemical Analysis of Neotropical Soils
2020In archaeological contexts, physicochemical soil analyses are essential to distinguish between the anthropogenic characteristics of the soil and those resulting from soil formation processes. This involves several physicochemical characterisations of samples, which have been used since the first half of the last century in various regions of the world,

The surface materials of Mars have been investigated through the spectroscopic observation from Earth and the orbiters, several types of detailed analyses by Viking landers, and the analyses of SNC meteorites of possible Martian origin. Especially, the X-ray fluorescence spectrometer, the GCMS, and three biological experiments of Viking landers provide
