Studies of a Scottish Drift Soil.: Part I. The Composition of the Soil and of the Mineral Particles which Compose it.

Abstract

Most of the soil investigations in this country have been conducted at Rothamsted or other parts of South Britain and the soils examined have been chiefly those overlying the stratified rocks of the southern half of England. These, however, are by no means typical of the whole of Britain and research is needed into soils found extensively in Scotland and other parts of Britain which differ greatly in their origin, nature and properties from those which have hitherto been the chief subjects to which British investigators have devoted attention. The various agricultural colleges are taking up the study of the soils of their respective districts, and when the Farm of Craibstone was acquired as an Experiment Station by the North of Scotland College, a series of soil investigations was immediately commenced.

Calcium, magnesium and potassium in clay, silt and fine sand fractions of some Finnish soils

“…This is in accordance only with the results on a Scottish Glacial soil reported by Hendrick and Ogg (1916). In the three English soils analysed by Hall and Russell (1911), and in ten American soils analysed by Brown and Byers (1932), as well as in the average values calculated by Hendrick and Ogg (1916) on the basis of the results obtained by Failyer, Smith and Wade in 1908 for ten Glacial soils, three residual soils and seven Coastal plain soils, the content of calcium is highest in the clay fraction, or in the finer silt material. This difference may be attributed to differences in the mineralogical composition and in the stage of weathering of the mineral material in Finland and in these other parts of the world.…”

The Ecology of the Cairngorms: Part 1. The Environment and the Altitudinal Zonation of the Vegetation

“…Chemically (if we apply the results obtained from analysis of a soil near Aberdeen, largely composed of granitic material) the particles contain considerable quantities of lime, potash and magnesia, but they have not undergone profound chemical weathering and show only superficial chemical alteration (Hendrick & Ogg, 1916). The content in replaceable bases is low and in agreement with results for acid soils in general (Hendrick & Newlands, 1926).…”

The genesis and development of two profiles of a drift soil in the north-East of Scotland. (With Two Text-figures.)

“…Previous investigations on these soils have been described by Hendrick,Ogg and Newlands(ii,i2,13,14,26). In the lysimeter investigations described by Hendrick(i5,16,17), there is a record of all that has been added to the lysimeters and of all that has been removed from them in the drainage water and in the crops.…”
