Pasture improvement and weed control. 

One of the driving forces behind getting a tractor was to allow us to start rehabilitating the precious soil on the Rock Farm.  Our aim is to create a balanced and healthy soil that supports low impact grazing.

One paddock on the Rock Farm is predominantly native pasture with remanent red box, red stringy bark and brittle gum trees.  I have been encouraging the regrowth of thousands of young trees around the older trees, and have been pleased to find the odd drooping she-oak – a vital food source for the Glossy Black Cockatoo.

One problem in this paddock is patches of Sifton Bush (Cassini Arcuata).  This native plant is an invasive weed, producing vast quantities of seed and rapidly colonising bare soil.

The mature sifton bush plant can produce up to 4 billion seeds a year.  It is unpalatable to most grazing animals and has been suspected of causing poisoning in lambs.  It is a declared weed in our area and we have a responsibility to control it.

The NSW dpi has an excellent page describing the Sifton Bush and its control.  http://weeds.dpi.nsw.gov.au/Weeds/Details/253

Whilst we have worked hard to clear some areas through pulling plants, it is hard work and time consuming.  I had used my mower for a few trials – but it was really hard work for the mower and was causing too much damage (to the mower). Burning is not effective due to the large amount of seedling reinfestation following a fire event.

And so our preferred method for larger areas of infestation is mulching.

Lucie the tractor has a 2.4 metre wide drum muncher that is effective at shattering the larger stems and mulching the leaves.  As this breaks down, it returns organic matter to the soil, hopefully improving the soil structure and microbial activity.

The tractor pushes over the mature plants easily – but beware of old stumps

The disadvantage of this method is that some of the sharp stumps remain, making it treacherous to drive a car over the mulched section.  Also some of the younger plants aren’t effectively broken down and may shoot again from damaged stems.

A much cleaner paddock

The end result is a paddock that not only looks a lot better, but has improved organic matter in the soil.  We have observed grasses recolonising the areas I have mulched as they receive better light and less competition from the sifton bush.

I expect to re-mulch these areas in another couple of years and perhaps take the opportunity then to re-mineralise the soil.  It wont be a quick process as soil takes tens of thousands of years to form, and a heartbeat to destroy.  It is all good fun and I am really enjoying the challenge of improving the Rock Farm.

Lucie the International 674 Tractor joins the Rock Farm

For a long time we have been discussing whether a tractor would be a useful addition to the Rock Farm.  To be truthful, I had been convinced for a while that I would find plenty of uses for one…  I just had to gain approval in principle to purchase one, and then find one that fitted the budget.  So for the past couple of years on-and-off I had been keeping my eye on Gumtree and other classifieds sites.

The main problem was deciding whether to buy a new Chinese tractor with all the features, or an older ‘name brand’ tractor.  Whilst the Chinese tractors represented excellent value for money, there were just as many horror stories out there which made me lean towards an older tractor from a known brand.

The other problem is that I had never driven a tractor.  So when the Local Land Services (LLS) advised me I had won a book voucher for answering a few questions on an online survey, it was an easy choice on choosing my book.

The book is, in a word, excellent.  Armed with a little bit of knowledge (dangerous situation), the perfect tractor came on the market just down the road.  A quick inspection confirmed it was going to be ideal for what we wanted to do on the Rock Farm – and the price was within our budget.

The vital statistics:

  • Name: Lucie
  • Type: International 674 4wd Tractor
  • Year Built: 1974
  • Fitted with: Front bucket / loader, Mulcher (flail mower).
  • Other accessories: Hay forks, stick rake

And it has been put to work.  I have been able to clean up piles of old wire, slash weeds, move piles of dirt, repair the driveway and pull out stumps.  It has transformed the way we move firewood from the paddocks to the house – saving double handling and time.  In short, it is a great addition to the Rock Farm.

We had deferred tidying up piles of old wire due to the labour it would have required…  now we have relished cleaning up the paddocks – even if lashing the wire to the trailer is a little challenging.

If you ask the Little Fisherman though, the tractor’s main purpose is to make jumps for his motorbike…

And it was a nice place to learn how to drive the tractor and play with the settings.  I might just have to admit that this is my new favourite toy!

I am sure that Lucie will soon feature in many articles on the Rock Farm, as we work to improve the pastures and soil health.  In the mean time, we can all enjoy some of its benefits.

Have I ever said how much I love living on the Rock Farm??
