How Often to Soil Test

No-Till Farmer released the results of a poll on frequency of soil testing among no-tillers.  Of those responding to the poll, 21% said yearly, and 25% said every other year.  I am surprised that 46% test that frequently.  We still get odd looks when we say we want to test every year.  It is true that you can do some mathematical calculations and come up with fertilizer needs, but soil tests are affected by moisture and temperature.  By testing every year, you learn if your soils are up to snuff under all environmental conditions.  Your soils don't read crop removal charts.  those charts are based on averages.  things could be very different on your farm.
