Intensified farming good for the environment sometimes

There is so much to learn on a farm. Aged just 5, Zoe can correctly identify plants from rye grass to melaleuca, wildlife from willy wagtails to wedgetail eagles and stock from heifers to old cows.

Yesterday, she came across the beautiful Paterson’s Curse for the first time. It’s not a problem here – the occasional plant pops up from time to time. Zoe took this pic to remind herself of it.

When I was Zoe’s age, ragwort was the weed we battled all summer. The paddocks turned a buttery yellow in late spring and the grass and other weeds on the river flat scratched at the ute windows. I haven’t seen a ragwort plant here in years and though the blackberries and thistles persist, they are at vastly reduced levels. The grass is also tamed to juicy, shin-high herbage. I think it comes down to the intensification of dairy farming in the last 30 years.

When my brother and I were out in the paddocks pulling up ragwort in the late 1970s and early 1980s, we had 120 cows on 300 acres. Now, we milk 265 cows on about the same area (with dry stock on another 200 acres), although we might be a bit overstocked. Back then, we had three paddocks and now we have 24 on the milking pastures.

Someone reminded me that Dad never paid any attention to daylight savings in the 1980s because he couldn’t find the cows in the dark in those massive hundred-acre paddocks! Now, they are contained in 3 to 4-hectare paddocks. It means the grass is far better managed and forms a thick sward that is harder for opportunistic weeds to penetrate. It also means we are more alert to changes in the pasture – there are no more “lost forests”.

Weeds are part of my master plan

“Weeds are part of my master plan” sounds like a phrase the Dr Evil of Dairy might use, doesn’t it?!

We’ve had a brilliant summer and autumn, which has made the grass and, ahem, the weeds, grow like crazy. Of course, there’s always a silver lining to every cloud and we’re seeing this as an opportunity to eradicate large banks of seed that has acccumulated over time without germinating.

Naturally, the weeds grow best on our best land, the river flats. The flats are next on my list of priorities for renovation and I don’t want new pastures overhwhelmed with thistles, nettles and other unpalatable – or even toxic – weeds.

The flats are rich, deep alluvial soils that retain moisture well during dry times yet drain well during wet times. They get us through summer and their pastures are always the quickest to recover but because the grass species are so old, quality is sometimes lacking.

Still, I’m a little reluctant to renovate them for a few reasons:

1. We rely on them being productive while our drier slopes are close to dormant over summer
2. They do flood and I don’t want to risk erosion
3. We need to be careful not to disturb the balance of soil life

The answer will be to temper my enthusiasm a little, take it gently, and renovate just a couple of our delicious river flat paddocks at a time.
