biosphere Flashcards
C - Podzol Soil
Podzols are found in areas which are cold and snowy in winter so in spring rapid snowmelt creates heavy leaching of soil, washing minerals down through A to B horizon
This leaves the soil less fertile at the top and ash grey.
R - Podzol soil
Found on steep sloped which enhances leaching.
This may cause washed out minerals to form an iron pan which is iron minerals cemented together, this further impedes drainage
O - Podzol soil
The temperatures are cold so few organisms se less air in soil.
Lack of biota means little mixing so horizon are very well difined
P - Podzol soil
Podzols are found in areas with coniferous trees which means acidic needles and cones decompose slowly to form more acidic humus
V - Podzol soil
The roots are short so the C horizon is not easily weathered
