Overview of the Soils report.

 

The Soils (SSurgo) report is a report that is located within both Surety Customized Online Mapping and Surety Pro Customized Online Mapping. In addition, the Soils report is used by growers (farmers), financial institutions, rural appraisers, insurance companies, auction companies, soil testing facilities, engineers, cooperatives just to name a few. The Soils report contains information on the soil survey from NRCS Source: http://www.nrcs.usda.gov/wps/portal/nrcs/main/national/home for most states except:


When evaluating land the following should be considered.



Classes and Subclasses:

Class:

     Land capability classification shows, in a general way, the suitability of soils for most kinds of field crops. Crops that require special management are excluded. The soils are grouped according to their limitations for field crops, the risk of damage if they are used for crops, and the way they respond to management. The criteria used in grouping the soils do not include the major and generally expensive land forming that would change slope, depth, or other characteristics of the soils, nor do they include possible but unlikely major reclamation projects. Capability classification is not a substitute for interpretations that show suitability and limitations of groups of soils for range land, for woodland, or for engineering purposes.

In the capability system, soils are generally grouped at three levels-capability class, subclass, and unit. Only class and subclass  are included in this data set.



Capability classes, the broadest groups, are designated by the number 1 through 8. 

The numbers indicate progressively greater limitations and narrower choices for practical use. The classes are defined as follows:

Class 1 soils have few limitations that restrict their use.

Class 2 soils have moderate limitations that reduce the choice of plants or that require moderate conservation practices.

Class 3 soils have severe limitations that reduce the choice of plants or that require special conservation practices, or both.

Class 4 soils have very severe limitations that reduce the choice of plants or that require very careful management, or both.

Class 5 soils are subject to little or no erosion but have other limitations, impractical to remove, that restrict their use mainly to pasture, range land, forestland, or wildlife habitat.

Class 6 soils have severe limitations that make them generally unsuitable for cultivation and that restrict thier use mainly to pasture, range land, forestland, or wildlife habitat.

Class 7 soils have very severe limitations that make them unsuitable for cultivation and that restrict their use mainly to grazing, forestland, or wildlife habitat.

Class 8 soils and miscellaneous areas have limitations that preclude commercial plant production and that restrict their use to recreational purposes, wildlife habitat, watershed, or esthetic purposes.

Note: While NRCS reports up to 8 classes, there are actually a total of 12 classes. Therefore, our Soils report displays upto 12 classes. The classes 9-12 will be for granite and such and will benefit engineers the most.

Subclass:

     Land capability classification shows, in a general way, the suitability of soils for most kinds of field crops. Crops that require special management are excluded. The soils are grouped according to their limitations for field crops, the risk of damage if they are used for crops, and the way they respond to management. The criteria used in grouping the soils do not include major and generally expensive land forming that would change slope, depth, or other characteristics of the soils, nor do they include possible but unlikely major reclamations projects. Capability classification is not a substitute for interpretations that show suitability and limitations of groups of soils for range land, for woodland, or for engineering purposes. 

In the capability system, soils are generally grouped at three levels-capability class, subclass, and unit. Only class and subclass are included in this data set.

Capability sub-classes are soil groups within one capability class. They are designated by adding a small letter "e", "w", "s", or "c", to the class numeral, for example, 2e. The letter "e" shows that the main hazard is the risk of erosion unless close-growing plant cover is maintained; "w" shows that water in or on the soil interferes with plant growth or cultivation (in some soils the wetness can be partly corrected by artificial drainage); "s" shows that the soil is limited mainly because it is shallow, drought, or stony; and "c", used in only some parts of the United States, shows that the chief limitation is climate that is very cord or very dry.

In class 1 there are no sub-classes because the soils of this class have few limitations. Class 5 contains only the sub-classes indicated by "w', "s",or "c" because the soils in class 5 are subject to little or no erosion. They have other limitations that restrict their use to pasture, range land, forestland, or wildlife habitat.

Iowa CSR/CSR2 (Corn Suitability Rating): This only applies to Iowa. It has a rating of 0 Worst - 100 Best. For more information visit: http://www.extension.iastate.edu/agdm/wholefarm/html/c2-86.html, Retrieved (6 September 2012) See also: Soils Report Options

  • CSR2 is a newly released rating and it is based on a more objective (formula based analysis) where CSR had some subjectivity applied to the rating.



In addition, you can also select individual crops that you only want to see data for or you can select all the crops and if there is data available, it will be displayed on our report See also: Soils Report Options.



In the event that you would like the Soils report with the CSR information and you would like a report containing the CSR2, then for example, you would select Soils in the right hand panel of which you will then be prompted to choose CSR or CSR2 (choose one or the other). Then report will generate and you can either save it to your machine, email or print it. After you are done with the Soils report with whichever CSR or CSR 2, you will need to close the report and click on Soils again in the right hand panel. Again, you will be prompted to choose CSR or CSR2 and you would choose (choose one or the other).

                                                                                                      Changes in Iowa soils Corn Suitability Rating from CSR to CSR 2

At AgriData, Inc. one of our goals is to give you the most accurate and up-to-date information we can. We do this by keeping our soils data consistent and updated with the USDA NRCS databases and Web Soil Survey. This data is the official federal soils data. These past several weeks, the USDA NRCS has been releasing a large number of updates to their soils databases across the country. In particular, there have been some major changes to the data for Iowa in regards to the Iowa Corn Suitability Rating (CSR), removal of yield information, and a resurvey/reclassification of a couple of counties' soil series.

Iowa State University is responsible for keeping the CSR data. The NRCS receives the CSR values and inserts them into their databases. Over the past year, Iowa State has developed CSR 2 in an effort to make the ratings more consistent, easier to calculate and the values more transparent to the public.

Additionally, CSR 2 is designed to work with the changes the NRCS has made in the way they classify soils for a given area.

NRCS uses a more data driven approach today compared to the 1970's when CSR was first introduced. At that time, soils were assumed to be 90 to 100% the same throughout a given soil series and CSR was assigned to that series. Today, NRCS accounts for all inclusions in the sil series and uses weighted averages of the inclusions to describe the series creating an inconsistency with CSR and the way NRCS classifies soils. CSR 2 is designed to remedy that and be more site specific.

As of October 1, 2012, the official NRCS Productivity Rating for Iowa will be CSR 2 and this value will be used in all USDA programs in Iowa that use a Productivity Rating. Examples include CRP rental rates, nutrient management plans and EQIP.

The count assessors have maintained their own CSR values within their given county and use the Iowa interpretive soils database or ISPAID as their standard. We are told that ISPAID will be updated to include CSR 2 values and at that time assessors will begin to evaluate CSR 2. 

At a AgriData, Inc., our standard is the USDA NRCS soils database so we will be including CSR 2 in our maps. In order to better communicate with you and your soils map customers, we will also have CSR data available. It is our understanding that CSR 2 will replace CSR in the NRCS data so please keep in mind that the twoare not designed to be correlated.

Nebraska SRPG (Soil Rating for Plant Growth): The SRPG is a measuring tool based on the analysis of the soils tests to ascertain the projected productivity of the cropland. For more information visit: http://www.extension.iastate.edu/agdm/wholefarm/html/c2-86.html, Retrieved (6 September 2012) See also: Soils Report Options.The coloring on the map is optional and it is so that the information can be discerned visually with relative ease on the map See also: Soil Color Options

In addition, you can also select individual crops that you only want to see data for or you can select all the crops and if there is data available, it will be displayed on our report.

SRPG is specific to Nebraska and it is available in our Soils report.
