To look at grinding our local limesands to see if it made them more effective.

• Grinding the limesand does make it more effective (ie increases pH more rapidly) and increases pH at a greater
• soil depth compared with using the same rate unground.
• However, we can get the same result from simply applying higher rates of unground product. Ultimately it comes back to cost effectiveness.
• To make it worthwhile applying ground product (and overcoming some application difficulties, ie the stuff blowing away!) we will need to get grinding costs down to less than the cost of about 2t of lime or about $14/t.
