WHAT IS A CSR RATING?
• Definition• An index that rates soil types based on
their productivity for row crop production• Index • What are the ranges?• What are the Assumptions?• Why not use yields?
Yields are not good measures of productivity, they change from
year to year because of weather and they change over time
because of technology.
CSR Assumptions
• Adequate Management • Natural Weather Conditions• Artificial Drainage where required• Soils lower on landscape not affected by
frequent floods• No land leveling or terracing
Erosion Class• None or Slight
– More than 7 inches of A or A plus E Horizon• Moderately Eroded
– 3-7 inches• Severely Eroded
– Less than 3 inches• Overwash
– 8-18 inches of recently deposited material above A Horizon

– CD– On Web
• Purchase the information
Using NRCS CD’s

in the farm!
