Study Set Content:
High sand, Low clay
Light soils
physically bound to the soil particles and is unavailable to plants
Hygroscopic water
Were plant is mainly dependent. Water that helds against the force of gravity, in pores of the soil
Capillary Water
drains out of the pore spaces after a rain
Gravitational water
Soil water between field capacity and permanent wilting point
Available water
water remaining after such draining. Mainly governed by the texture of the soil
Field capacity
if the water is not added to the soil, the rate absorption of water is insufficient
Permanent wilting point
water remaining after such draining. Mainly governed by the texture of the soil.
Field capacity
it affects both the soil and the plants
Soil pH
Thrive in acidic conditions
Cranberries
Toxic to the roots of other plants and mycorrhizae do not survive in soils with pH extremes
Unusually acidic or alkaline
if high enough, inhibits the growth of nitrogen-fixing bacteria
Acidity
minerals such as copper, iron and manganese to become less available to plants
Alkalinity
where does acid soil tend to be common
areas of high precipitation where, significant amount of bases are leeched from the topsoil
makes alkaline soils acidic
Sulfur
Common agricultural practice to counteract soil acidity by adding calcium or magnesium
Liming
makes alkaline soils acidic
Sulfur
Bacteria converts to sulfuric acid same as
when nitrogenous fertilizers are added
lighter and lower portion of the soil
E-horizon
Most higher plants have a
erect shoot system
