Somewhat poorly drained. Saturated hydraulic conductivity, measured in micromete
ID: 153956 • Letter: S
Question
Somewhat poorly drained. Saturated hydraulic conductivity, measured in micrometers per second, is 4.23 to 14.11 (.6 to 2 inches per hour). Runoff is low. Seasonal high saturation occurs at depths as high as 46 cm (1.5 feet), typically during the months of March through June in normal years. A--25 to 43 cm (10 to 17 inches); very dark gray (10YR 3/1) clay loam; moderate fine subangular blocky structure; friable; about 5 percent gravel; common black (10YR 2/1) worm casts; slightly acid; gradual irregular boundary. [8 to 38 cm (3 to 15 inches thick)]

5) Review the OSD for the Nicollet soil in lowa. Using the color information, comment on the likely drainage class of that soil. (4 pts) Color at 30 cm: Color at 90 cm: Value indicting drainage issue Chroma indicating drainage issue: Comment on evidence of drainage issues in this soil?Explanation / Answer
Color at 30cm: Common Black
Color at 90cm: Very Dark Grey
Value indicating Drainage issue: Saturated hydraulic conductivity = 4.23 to 14.11
Chroma indicating Drainage issue: Clay Loam, Worm Casts
Evidence of Drainage issues in the soil:
To overcome the drainage issues in the soil, do the following,which involves digging deep trenches in the wet areas so that the trenches lead out to the street, a storm drain or a pond. After covering the bottom of the trench with stone, lay the drain tile on the stone and then cover it with more stone and, finally, soil. Drain tiles are flexible, plastic tubes which have holes in them. Water drains through the ground, into the trench, through the rocks, into the holes and out the end of the drain tile into the street, drain or pond. The tile must be slanted so that the water can drain properly. If water is running into your yard from a slope or hillside, it can also be diverted by building a swale. A swale is a long, slightly raised mound of soil that diverts the water off to the side of your property or to a place that is better drained. Here again, a landscape contractor or drainage expert can be of help in providing advice.
