pH - a notation used to designate the relEitive acidity or alkalinityof soils and other materials .A pH of 7 .0 indicates neutrality,higher values indicate alkalinity, and lower values acidity .phase,soil - a subdivision of a taxonomic class based on soilcharacteristics or combinations thereof which are consideredto be potentially significant to man's use or management ofthelandplastic limit - water content at which a soil will just begin to crumblewhen rolled into a thread approximately 3 mm in diameter .plasticity index - the numerical difference between the liquid and theplastic limitprofile -a vertical section of the soil throughout all its horizonsand extending into the parent materialrelief - the elevations or inequalities of the land surface whenconsidered collectively .Minor configurations are referred toas "microrelief" .seepage (groundwater) - the emergence of water from the soil over anextensive area in contrast to a spring where it emerges from alocal spotsolum (plural - sola) - the part of the soil profile that is abovethe parent material and in which the processes of soil formationare active . It comprises the A and B horizons .texture (soil) - the relative proportions of the various sized soilseparates in a soil asdescribed by the textural class namestill - unstratified glacial drift deposited directly by ice and consistingof clay, silt, sand, and boulders intermingled in anyproportion
117turf (as used in this report)- the abundantly rooted (usually surface)organic layer common in alpine soils .This dense root matextends into the surface mineral horizon . This layer is designatedby the letter L .watertable - the upper limit of the part ofthe soil or underlying rockmaterial that is wholly saturated with water
