How does the Tri-State (Indiana, Ohio, Michigan) calculator determine my lime needs?
Overview:
The Tri-State calculator can be used to help create lime recommendations.
Answer:
The Tri-State calculator utilizes the following equations:
|

|
If OM > 20 & pH < 5.0 |
Typical Lime Rec = (32.9 - (6.31 * pH)) * 2000 |
|
|
If CEC <= 7 and OM <= 20 and pH <= 5.9 |
Typical Lime Rec = 4000 |
|
|
If CEC <= 7 and OM <= 20 and pH > 5.9 and pH <= 6.2 |
Typical Lime Rec = 2000 |
|
|
If CEC > 7 and OM <= 20 and pH <=6.2 |
Typical Lime Rec = (60.4 - 0.87 * (Buffer pH * 10)) * 2000 |
