Practice exam #3 - QUESTION 1
1.)• Addition, Translocation, Transformation, losses
2.)Translocation-Earth worms moving material Transformation- Decomposition, oxidation and reduction (Al, Fe) Losses- wind, erosion, leeching (in soil solution) Addition- Fluvial deposition, glacier deposition
3.)1.)Regosolic- Addition
2.)Brunisolic- Losses- leaching of soluble salts
3.) Luvisolic- translocation- of clay sized particles from A to B
4.) Gleysolic- transformation- oxidation and reduction reactions
5.) Chemozemic- Addition- accumulation of organic material
6.) Solonetzic- transfer/Addition
7.) Podzolic- transformation- chemical and biological transformations of primary minerals
8.) Organic- transformation- decomposition
9.) Crysolic- translocation- in freezing in thawing cycles.
10.) Vertisolic- translocation- wetting and drying cycles
1. a) Translocation, Transformation, Additions, and Losses
b)Translocation: Movement of material within the soil - organic matter, Transformation: Decomposition of organic matter - nitrification, ammonification (inorganic-organic) etc., Additions - the addition of organic matter to the soil, Losses: loss of nutrients through leaching - nitrate.
c)*making assumption that enrichment could be considered addition*
Regosolic: addition of material, Brunisolic: addition of Fe and Al, modified horizon (transformation?), Luvisolic: addition of silicate clay, Gleysolic: translocation of water (changing water table0, Organic: addition of Fe and Al, modified (transformation?), the addition/enrichment of organic matter, Chernozemic: addition of organic matter, Solonetzic: high Na (not sure which major category this belongs to) and addition of silicate clay, Podzolic: addition Fe and Al and addition of organic matter, Cysolic: translocation of thawing material, Vertisolic: translocation of mixing soils
here Gretchen you are not asked to identify whether or not it is an addition, transformation, translocation or loss, but simply the dominant soil forming process for each soil order.
