What's unique about a 2:1 correct answers 2 tets and 1 oct
1:1? correct answers 1 tet and 1 oct
Iron/ Al oxides ? correct answers low CEC capacity, common in highly weathered soils (oxisols)
humus? correct answers High CEC, enhances soil fertility
what is permanent charge correct answers Occurs from isomorphic substitution and is formed in
the phyllosilicates via Mg or Fe substitution for Al in the octahedral lattice. Mg for Al in tet
What is pH dependent charge? correct answers Temporary charge
define flocculation correct answers Individual particles stick
together to form aggregates of
particles or floccules. Such aggregates do not move in the soil solution and form
the basis for soil structure.
define dispersion correct answers Aggregates do not form
Each particle behaves as an
individual.
Without aggregation, water,
air, and root movement in the
soil is inhibited.
Dispersion is not a desirable
, characteristic of productive
soils.
