Basic soil science pertinent to forest<br />
management <strong>and</strong> engineering.<br />
• <strong>Soil</strong> is: _______________....<br />
– It is between the bedrock <strong>and</strong> your feet <strong>and</strong> it is<br />
the result <strong>of</strong> the 5 soil forming factors:
1. Parent Material<br />
2. Topography<br />
3. Climate<br />
4. Biota<br />
5. Time<br />
<strong>Soil</strong> Forming Factors
Major <strong>Soil</strong> Parent Materials in <strong>Maine</strong><br />
Dense basal glacial till ( > 1.5m to bedrock)<br />
- Catenas: Marlow, Chesuncook, Perham, Caribou<br />
<strong>and</strong> more<br />
Glacial till ( < 1.5m to bedrock)<br />
- Series: Monson, Lyman, Tunbridge, Ragmuff,<br />
Elliottsville, Rawsonville, Hogback, etc.<br />
Marine sediments<br />
- Catenas: Buxton, Boothbay
Major <strong>Soil</strong> Parent Materials in <strong>Maine</strong><br />
Glaci<strong>of</strong>luvial (outwash)<br />
- Series: Adams, Croghan, Madawaska, Searsport,<br />
<strong>and</strong> more<br />
Ablation till<br />
- Series: Hermon, Danforth, Monadnock, etc.<br />
Organic soils (bogs)<br />
- Series: Bucksport, Wonsqueak, Moosabec, etc.
Topography: dictates<br />
accumulation vs. erosion,<br />
drainage, aspect, etc
Biota: in<br />
<strong>Maine</strong> this<br />
means<br />
(mostly)<br />
spruce-fir<br />
<strong>and</strong> N.<br />

Basic soil science pertinent to forest<br />
management <strong>and</strong> engineering.<br />
• <strong>Soil</strong> forming factors determine the soils that<br />
occur at any given point.<br />
• Thus they determine the important features<br />
for management.<br />
• The features most important for<br />
management are primarily related to site <strong>and</strong><br />
parent material factors.
Basic soil science pertinent to forest<br />
management <strong>and</strong> engineering.<br />
• Some soil features important to <strong>Maine</strong><br />
forestry management:<br />
– Drainage/seasonal high water table<br />
– Strength/erodibility characteristics<br />
– Depth to bedrock<br />
– Source for surfacing material (textural)<br />
– Fertility <strong>and</strong> acidity
