Northern Nebraska | I care but it has no value. If I want to be sentimental I'll keep one. Not a filing cabinet full. The values on a soil test change so vastly in just 3 years. Anything older than that is unreliable anyway. Besides, anything that I took before I started using GPS is unrepeatable. So I really can't say if things had improved anyway. Because you can never know what that exact location would have tested before. | |

How long do you retain soil test results?
