Phosphorus retention project around Lake Rotorua

I listened to the RNZ rural news podcast linked below back in July 2012 which includes a review of a water quality related project around Lake Rotorua. 2:30min in is a discussion on the “P Project”. Their project does seem to have some links to keyline plowing.

No reference to biochar in following 2010 report (but hardly surprising)…
