Land Suitability Rating System

Help and Documentation

The purpose of these html based files is to provide help and background information to anyone using the Land Suitability Rating System (LSRS) and the LSRS software.

The numbering used here for sections, figures and tables is corresponds to the LSRS Manual (Technical Bulletin 1995-6E) - Land Suitability Rating for Agricultural Crops - 1. Spring-seeded small grains. This has been done to facilitate referencing the information here to the LSRS Manual and vice versa. Portions of the LSRS manual have been converted to html files and included here for convenience. Not all figures have been converted and included. The reader is referred to the LSRS Manual for complete information (an electronic PDF version of the file has been included - see below.)

Links are provided to the main sections of the LSRS Manual and also to Implementation Notes which correspond to those sections.

This documentation package includes SLC / NSDB extensions.
