Podzol Flashcards
what does low temperature in the soil lead To?
slow decompositiom
what produces the humus (acidic layer) in a podzol
conferous needles and cones
high precipitation leads to what?
leaching
what forms the iron pan?
leaching, which is the downward movement of the aluminium and iron oxides
what leads to the reddish brown B horizen?
illuviation
the introduction of salts or colloids into one soil horizen from another
what leads to well defined soil horizons?
limited soil biota
what do shallow roots mean?
limited absorbiton of deap leached materials
what type of humus is formed from coniferous needles and cones?
acidic mor humus
what trees grow on podzols
coniferous trees
christmas trees
what forms between the A and B horizons due to leaching?
an iron pan
what colour is the A horizon in podzols?
grey due to eluviation
(leaching of minerals)
what causes the reddish brown colour of the B horizon?
illuviation (where iron and alluminium oxides accumulate)
why are the horizons in podzols so well defined
limited soil biota and minimal mixing
how do steep slopes influence podzol development?
increase leaching and reduce organic matter accumulation
where are podzols usally found?
steep slopes and lower altitude
