It runs for a kilometer across the travelling stock reserve, James, from where it comes in through the north-west corner. I walked the length of the strip last Friday, the lovegrass varies from one to five meters wide. Interestingly, the water source (or the natural pipe it runs in) maintains much the same depth below ground (1100 mm to the water surface), width and depth of content (1 meter x 1.5) for the whole distance. Also the aluminium/calcium ratio hardly varies from 94/145 ppm.It really is an interesting phenomena that patch of love grass.
Obviously it's important in that the phenomena could be pointing to a way to solve the lovegrass / serrated tussock problem. However, I find the mullein 'overdose' almost as interesting. The sulphur level generally is only down a little, certainly not enough to justify all the plant that is there. In any case, the whole TSR has a similar level of weed growth everywhere with very little native grasses; right now it doesn't need any more sulphur.
Personally I think what we are seeing is a sulphur sink. Two, in fact. Both stretches are underpinned by underground watercourses. One of these runs into and out of a buried pool at least 80 m long by 50 m wide. The mullein implants sulphur in the soil, the watercourses pick it up and carry it downstream to where it is needed. My pendulum indicates 20 kms.
Incidentally, everything the pendulum has indicated has been confirmed using dowsing rods. Also the breakfast thingo I mentioned in my original post I 'pulled' on a sceptical government resource management person last week.
