We have a test kit called the Greenleaf Farm Lab, developed by the CSIRO. It's quite a few years old now, and hasn't been used for quite some time. (Before my time here). Our HT has dragged it out and would like to use it. It uses a few reagents labelled: P1, P2, P3, (for phosphorus testing) and N1, N2, N3, N4 (for nitrogen testing). Would anyone out there have one and know what these reagents are? The tests are performed on leaves, not soil. Can also test water samples. I have a manual, but the instructions say to order replacement reagents when supply is low. (from the supplier of course, whoever that may be). I've checked the CSIRO website, and googled, but no reference to this kit anywhere. Any ideas??
