" Using soil moisture probes to make better farming decisions 20 November 2014 South Australian grain grower Tom Robinson, Halbury, talks about his experiences using soil moisture probes on the family farm... The way 139.189: I'm looking at it now is that possibly we might be able to grow a winter cover crop 143.049: to make more ground cover and also have a diverse mix of a cover crop in there, and 148.4: then we'll kill that crop and then sow sunflowers into it... We're drying out 166.43: our profile; by having a winter cover crop we're growing more cover, more ground cover; 171.769: we're creating more diversity; we're getting a legume back into our system; and then we're 176.209: also able, by doing that, to grow a different crop, a summer crop, which is hopefully better 183.7: for our end goal which is soil health...

Zones based on water use efficiency and variable rate inputs are helping Peter Kuhlmann remain viable on his low-rainfall property near Ceduna, South Australia... At the SPAA Expo in South Australia in February, Peter explained the farming practices he uses to collect and conserve the limited rainfall received by his property... One tool to help maximise crop water use and minimise water loss is stubble retention, using: no-till with knife points - tillage beneath the row is used to help reduce the root disease Rhizoctonia; presswheels; wider row spacing - less crop competiton and allows inter-row sowing to improve seedling establishment due to protection from wind; and early and dry sowing with good seed and nutrient placement...

" GRDC Grains Research Updates 5-6 March 2013, Northern Region, Goondiwindi QLD. Neal Dalgleish 24 September 2013 Neal Dalgleish, CSIRO Sustainable Ecosystems, talks about new technology for measuring and advising on soil water... Soil water can be effectively monitored to assist managers in crop decision support... Given the vagaries of the system, there are a number of technologies which will provide a level of information useful in decision support without excessively high levels of investment...

Based on this, we estimate that water used by weeds in the wet weedy (+I+W) treatment up to the midfallow period was 593 x 1688 (biomass) / 10 000 = 100 mm; for the dry weedy (-I+W) treatment water use is estimated at 30 mm... The results showed that Zn uptake by plants and in the grain could be most improved by mixing Zn with N and P (as technical grade MAP and ammonium nitrate dissolved in water) in a single solution and injecting it into the soil to a depth of 40 cm... Results from our laboratory experiments have confirmed that fluid forms of P have very different physical and/or chemical effects on soil in the fertilizer band in calcareous soils, and improve plant P uptake...
