Managing pastures through a dry spring to safeguard summer feed supplies (opens the original)
Read excerpt
For many central and northern farmers it has been a challenging year. Rainfall overall has been well down, there was a late start to the autumn break, with rain arriving just in time to keep crops and pastures growing, but leaving little soil moisture reserves to cope when conditions eventually warm up and dry out. For large parts of the state native perennial grass with naturalised or introduced legumes is the mainstay pasture type for the livestock business. Provided soil fertility is adequate
Unlocking nitrogen: why lucerne remains the king of fodders on NSW farms (opens the original)
Read excerpt
This column over the years has given a lot of attention to the value of tropical grasses for most areas of NSW. But they do not replace the value and role of lucerne as a productive, high-quality legume able to build soil nitrogen and, with care, play a valuable rotational role. Lucerne favours non-acidic soils with little to no aluminium toxicity. It favours deep, well-drained clays to light loams. Some farmers regularly have stands that last up to 20 years, though it is more often seen as a fo
New research opens up summer crop options by de-risking southern sorghum (opens the original)
Read excerpt
For much of her working life as a research and development agronomist with NSW DPIRD, Dr Loretta Serafin (now of Serafin Agricultural Services ICAN Rural) has focused on technology to improve reliability and feasibility of grain sorghum in lower summer rainfall environments. Her studies have helped farmers as far south as Dubbo and west to areas such as Walgett to successfully grow sorghum when stored soil moisture levels are suitable. In a paper Including sorghum in drier areas - when, where, w
Revolution: taking the world from famine to feast, thanks to fertilisers (opens the original)
Read excerpt
It was not that long ago that the world was plagued by regular food shortages, despite a much lower population than today. The evolution of commercial fertilisers like superphosphate, MAP and urea has been a major reason why this threat to humanity has evaporated. Today's world, with its population of eight billion, has never seen better food availability. "Figures vary, but estimates suggest that 50 per cent of crop yields worldwide are attributed to the use of commercial fertilisers", a newly
Flexibility key: planning for dry times when everyone's drought is different (opens the original)
Read excerpt
I am sure everybody is sick of unsolicited advice on how to manage through a drought. But to minimise future drought problems, and perhaps ongoing ones, there are lessons that are worth learning. I have seen countless examples of issues like water supply, feed reserves and degraded paddocks. Knowing how to avoid these is important. In our own case there was no more important aspect than having a plan, though it needs to be flexible and often gets upgraded. No drought or near-drought is ever the
