Top 12 IRR Rated Soils

7 Are Agricultural Soils

In total the Brown Report1 rated 56 soils of the county’s 111 soils. Twenty (20) of the rated soils (38%) were agriculture soils as defined by the Soil Survey2 (pages 178 - 181, Table 5).

Top 12 IRR Rated Soils Seven of the top 12 IRR rated soils with an IRR 4.0 or greater (58%) were agricultural soils as defined by the Soil Survey. All these agricultural soils had a capability class rating from II - IV irrigated through Class VI unirrigated.

The average IRR rating for all seven agricultural soils was 4.63. The average IRR rating for the five soils with capabilities Class IV irrigated and nonirrigated and Class VI nonirrigated was 4.7.

The internal rate of return (IRR) system for analyzing soils is part of the Josephine County Comprehensive Plan and code.3

The Hugo Neighborhood Association has concerns with the application of the IRR system.4

More Information

Agricultural Soils The Soil Survey identified 46 agricultural soils that with a high level of management were suitable for alfalfa hay, grass hay, pasture, and corn silage (pages 178 - 181, Table 5).

Non Rated Soils LUBA has ruled that designation of land as agricultural land does not, of itself, mean the land is not also suited to protection as forest land. Westfair Associates Partnership v. Lane County, 25 Or LUBA 729, 737 (1993). It has further ruled that a NRCS non-rating provides no information, quantitative or otherwise, pertinent to the statutory test of whether a soil is capable of producing defined levels of wood fiber (ORS 215.750; Carlson v. Benton County, 34 Or LUBA 140, 149 (1998).
