Jul Låg
Jul Låg (13 November 1915 - 2 February 2000) was a Norwegian scientist and soil researcher. Biography He was born in Flesberg in Buskerud, Norway. He grew up on the farm in Flesberg. After elementary school he was a farm laborer for several years. He took the dr.agric. degree in 1949. He also studied geology at the University of Oslo (1942–43). He studied under graduate fellowships and scholarships from (1942–45). He examined and described the rare Norwegian soil types, including rendzina-like soil. Låg has examined the supply of plant nutrients in precipitation in Norway. He hired scientists in the field both at home and abroad, organized annual symposia where he gave several speeches, and he edited the books where the various contributions were published. An area of research, which he started just before he retired, was the impact of soil and rock properties on human and animal health.

Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
