Soil and landscape effects on water table depth in three Indiana soils

McClelland, James H. January 1994 (has links)
Depth to water table in soils influences soil properties such as color and horizon thickness and, in some cases, determines soil classification under Soil Taxonomy. The objective of this study was to determine the depth to water table in three Indiana soil series and to evaluate the effect of soil series and landscape on water table levels. The three soils studied were moderately well drained Glynwood, somewhat poorly drained Blount, and poorly drained Pewamo soil series. The effect of soil horizon on water table levels was also examined.Data were collected from 3/21/94 to 6/6/94 at the Hults Environmental Learning Center in Albany, Indiana. The effect of soil type on water table levels was observed as measurable differences in drainage characteristics in the three soil series. Soil horizon had limited effect on water table fluctuations. Water percolated easily through all A horizons. Water temorarily perched upon the B horizon in the Glynwood soils. Landscape position appeared to play a limited role in water table fluctuations. / Department of Natural Resources and Environmental Management

Soil water balance of intercropped corn under water table management

Qureshi, Suhail Ahmad January 1995 (has links)
A one year water table management field study was conducted on a Soulanges sandy loam soil in Soulanges county, Quebec. Two controlled water table levels, i.e. 0.5 m and 0.75 m from the soil surface, as well as free outlet conventional drainage treatments were established in monocropped corn (Zea mays L.) and corn intercropped with ryegrass (Lolium multiflorum Lam) plots. / Cropping system showed no significant effects on evapotranspiration, and on soil moisture distribution. It was observed that the 0.5 m and 0.75 m controlled water tables (CWT) provided the same soil moisture trends in both cropping systems. The soil moisture was always higher in controlled water table plots compared to freely drained plots. The water use efficiency of 0.75 m CWT in both cropping systems was high compared to 0.5 m CWT. / The soil moisture contents at three depths were only 2% to 10% less in intercropped plots compared to monocropped plots. The soil moisture was 12 to 13% higher in CWT plots compared to freely drained plots for both cropping systems. The soil moisture in 0.5 m CWT and 0.75 m CWT plots was not significantly different. The average water table levels in monocropped plots were not significantly different from intercropped plots.
