AGPR201 14 01 Soil Morphology
Abstract The zone of saturation plays significant roles in decisions regarding soil classification systems and land use both present and potential. This study was conducted to determine the status of water tables, morphological features, and groundwater hydrology and to evaluate the zone of saturation on selected soils Aquolls and Hapludolls of a Mollisol catena. Water table depths and the amount of precipitation were measured for a year period on five soils formed in glacial till or till-derived sediments in central Iowa. Results show that the depth of the water table, duration of saturation, morphological features, and recharge and discharge to groundwater varied with geomorphic position in the Mollisol catena. In general, soils on summit and shoulder positions Hapludolls are not saturated and have high chromas without redoximorphic features in the B horizon, have deeper water tables, and have maximum fluctuation of water table levels. The soils on toeslopes and depressions Aquolls have the shallowest water tables, have the longest time of saturation, and have B horizons with gray matrices, bright mottles, and Fe-Mn concretions.
Eurasian Soil Science. Data on clayey swelling soils with gilgai microtopography are systematized. Classifications of gilgai microtopography representing regularly alternating microhighs and microlows are discussed, and its geometric parameters under different landscape conditions are considered.
