PRECIPITATION
-
-
-
little rain in
winter
why? low temps means air
holds moisture, is dense +
does not rise
-
Vegetation
taller, more established
vegetation (trees+shrubs)

CALCIFICATION
-
-
- SPRING -
- melting snow + showers cause
water to move through soil
- weak leeching carries calcium
carbonate through soil
- SUMMER -
- hot temps + lack of rain causes
water to move UP through soil
(capillary action)
- rising water carries calcium
carbonate towards surface of soil
-
-
Soil
Characteristics
- profile
- deep topsoil (A)
- no sub-soil (B) as
minimal leeching
- seasonal capillary action
- depth
- quite deep 1-2m
- rapid weathering of parent
material + annual addition
organic grasses produce deep soil
- colour
- dark brown (even black)
- high humus content
- rich organic material breaks
down + releases humic acid
- stains soil dark brown
- acidity
- neutral pH 6/7
- limited leeching +
lime rich parent
material
- texture
- clay-loam texture
- drain well
- retain essential nutrients &
water for plant growth
- loess parent material promotes
mixed texture
- structure
- crumb structure
- abundant humus
- highly active soil organisms
- soil stays stable in heavy
wind/rain & deep roots retain water
and heat in soil
