| Abstract: | Hydrologic analyses often involve the evaluation of
soil water infiltration, conductivity, storage, and plant-water relationships.
Definig the hydrologic soil water effects requires estimating soil water
characteristics for water potential and hydraulic conductivity using soil
variables 0such as texture, organic matter and structure. Field or laboratory
measurements are difficult, costly and often impractical for many hydrologic
analyses. Statistical correlations between soil texture, soil water potential
and hydraulic conductivity can provide estimates sufficiently
accurate for many analyses and decisions. Saxton and
Rawls (2006) developed soil water characteristic equations from the available
USDA soil data base using only the readily available variables of soil texture
and organic matter. This paper presents the soil characteristics estimated at
RD 838 of Indira Gandhi Nahar Priyojana, Stage – II using soil water
characteristic equations developed by Saxton and Rawls (2006). The study area
is found to be predominantly covered by loamy sand and sand, wilting point varying
from 0.003 to 0.038, field capacity 0.048 to
0.106, saturated moisture content 0.392 to 0.417 and
saturated hydraulic conductivity 63.19 mm/hour to 197.08 mm/hour. |
