@Colinhendee cool, I am about 5 hours behind you so depending on time I may not see it until the morning, I think running the keyline plow just before coming into the rainy period might be the best option for many of the compaction, infiltration and gas exchange problems, open it up and get the roots down to hold it open.

For the weed species do you think this is an issue of of a lack of animal impact or are they aggressive perrenials that bounce back quickly.

How are you set up for being able to get across the ground with sprayer, fertiliser spreaders etc?
