Operation: Energy STIR Direction and Speed (O 03)

The "O 03" operation line supersedes the "O 01" coded operation line defined above. It includes three additional parameters to support the "Soil Quality Index", "Energy STIR (Soil Tillage Intensity Rating)" and "fuel usage" calculations used by NRCS. The parameters are:

Diesal Energy per Area
Diesal energy units consumed per unit area covered.

Soil Tillage Intensity Rating
Soil Tillage Intensity Rating(STIR) value assigned to the operation.

Speed
Operation travel speed.

Direction From North
Travel direction clockwise from north, in degrees.

Standard Speed
Speed at which some fo the physical processes have coefficients specified. In WEPS, many of these coefficients are then adjusted internally based upon travel speed, as well as other parameters.

Minimum Speed
Minimum operation travel speed. This value determines the lower limit at which WEPS will adjust certain process=specific parameters that are influenced by speed.

Maximum Speed
Maximum operation travel speed. This value determines the upper limit at which WEPS will ajdust certain process-specific parameters that are influenced by speed.
