Ag Handbook 296 Update Project


Jim R. Fortner, NSSC
Status:

Memo sent out about a year ago announcing the project and timeline for completion

Team established at NSSC to coordinate the project

Jim Fortner, soil scientist, chair

Sharon Waltman, soil scientist

Stan Anderson, editor

Johnny Patterson, forester

Dave Lightle, agronomist

Curtis Talbot, range mgmt. specialist

Bob Engel, soil scientist

Lyle Steffen, geologist

New format for description of MLRAs and LRRs identified

State offices and MLRA offices have designated those MLRAs to be significantly modified

Preliminary line work for these modifications has largely been submitted

NSSC team in process of drafting revised descriptions for those MLRAs that will not be significantly modified


  • 1997 NRI summaries of landuse/landcover distribution by MLRA has been received and to be used in updated descriptions

  • State and MLRA offices are working on refining MLRA boundaries and writing descriptions for those to be significantly modified


Timeline:

Due to several reasons causing delays, a revised timeline has been established as follows. These dates have been coordinated with similarly revised dates for the companion STATSGO update project. In general, the dates have been delayed about 6 months to 1 year.

2

NSSC to send draft updated MLRA descriptions of existing MLRAs to MO/SO for review

6/30/2001

3
