Keeping a driveway

When we built our carport at the Rock Farm, we knew eventually we would have to do some work on the driveway. The carport has been one of the most useful additions to the liveability of our house – with the shade welcome in summer and the lack of frost a bonus in winter for early morning starts. Building the carport was a challenge (https://rockfarming.com/2019/11/22/making-shade/) however it also created other problems that we knew we would need to address one day.

The access to the carport used a track through the garden that had been formed but not used much for the next 40 years. A large concrete pipe carries the drive over a small gully. The problem is to do with the volume of water that comes down the gully. Normally the gully is dry or barely a trickle, however on occasion it comes in torrents, through the pipe and overflowing across the road. Jo always wanted a babbling brook outside the back door…. perhaps not with all-or-nothing features of this one!

When the water subsides, the damage becomes apparent. Over the past 18 months of regular driveway use and occasional floods, the remaining base has become narrower. An attempt to address some of the drainage was of limited success (https://rockfarming.com/2020/08/31/drainage-trees-cattle-and-some-sad-news/). With the driveway now unsuitable for anything but cars, it was time to call in our neighbour, who happens to have his own bob-cat and excavator business.

Lou is an absolute master of his machines, and made short work placing large concrete blocks to form a wingwall on both sides of the driveway. The laser dumpy level helped ensure the blocks were all on the same plane – making the job far neater and more precise than I could have achieved for a fraction of the time.

The last job for us to do was to install the headwall. For this I enlisted some school holiday labour. The boys were in a word fantastic, and were soon mixing the concrete to a perfect consistency. They learnt some important skills, and I really enjoyed the time working with them on this little mud pie project.

Lou also dropped a load of large recycled concrete over the boggy section – making our driveway a far safer all weather proposition…. well except for the last run up the hill to the house. But that will be a job for another day 🙂

We are thrilled with the change to the driveway. Whilst it still isn’t finished properly, it provides far better access to the house for all vehicles, including RFS tankers. A special thanks to Lou for his mastery of his machinery and the school holiday helpers.

Curse of Mavis – Mange Mite

In April this year we rescued Mavis, the Muddle Headed Wombat, who was badly affected by mange. Mange is caused by the mange mite, sarcoptes scabiei, which lives on and under the skin of mammals. It causes a particularly painful itch, and eventually leads to the animal’s death, and is sadly common amongst our native wombats. Mavis was successfully rescued and is making a full recovery at a nearby wombat sanctuary.

Unfortunately the mite that caused Mavis’ discomfort is still about and causing havoc. A couple of days ago I found evidence that it is affecting the cattle, and determined I needed to take action.

The bare skin patches, especially in the calves suggest that the mite has started to affect their behaviour. Cattle with the mite put on less weight and are obviously uncomfortable. My research suggested treating the cattle with moxidectin was the most effective and least harmful approach to treating the mite. The cattle seemed to want to follow me when I brought them into the yards early one frosty morning.

The reason I chose moxidectin to treat the cattle is:

  • It is effective on the mange mite sarcoptes scabiei
  • It is safe for dung beetles
  • It has no with-holding period for beef cattle and no export slaughter interval.

I am now in a waiting game to see whether the treatment is effective, and will keep you posted.

As a side note, I had some old moxidectin in the shed. It was tempting to ‘use it all up’, however I am glad I went to out local ag store. Roger explained to me how old drench goes off and can cause the chemical to be less effective, whist leaving residue in the cattle. Whilst the drench is eye-wateringly expensive, it works out to be much more palatable when calculated on a cost per head basis to treat the cattle – even for small producers such as the Rock Farm. Roger even gave me a new applicator, which allowed me to accurately deliver the required 10mL/100kg of live-weight, ensuring we give the optimal dose per animal.

The out of date drench remains difficult to dispose of safely, but the regular chemical muster remains a must do activity on my calendar. We did it a couple of years ago when we bought the property ( https://rockfarming.com/2018/11/25/farm-chemical-disposal-with-chemclear/ ), and I keep an eye on when I am able to do the same again.
