Developing and testing innovative, practical and  reliable methods for incorporating lime into acidic sandplain subsoils locations
Aims

To evaluate the effectiveness of two bolt-on attachments to a deep ripping tine at lime incorporation.

Key messages

The Long Bottom Boots functioned reasonably well at first, but tended to plug with soil from underneath after multiple passes and on finer textured soil to the south of the trial area.

We think that a design that was wider at the back (60 – 80 mm) and therefore more open would improve soil flow down the boot, and reduce the risk of plugging.
