Lubeck farmer Peter Taylor (left) and Joe Boisen inspecting harvest options for a flood-damaged wheat crop... Even though some locals had started to believe poet Dorothea MacKellar was wrong, and rain would never return to the Wimmera, the entire region has suddenly flipped from being in a 13-year drought to sitting in water... For paddocks not submerged, a large flush of nitrogen is expected to have become available to this season's crops through breakdown of organic material - a process known as 'mineralisation' and potentially providing savings on fertiliser...

The CSIRO has discovered an Australian strain of a "mineral-eating" fungus that promises to release nutrients from soil minerals and boost crop yields... The strains that have now been discovered can release nutrients from soil minerals... To date, the major limitation has been the identification and development of strains of Penicillium suited to local soils and environmental conditions...

It is grown to produce high quality hay and provide high protein forage for grazing... Lucerne supplies quality hay for animals in intensive systems... Lucerne can improve soil N fertility on run-down soils and will improve wheat yield and elevate grain quality to prime hard for a number of years, when the land is returned to crop...

Feedlot manure can provide half price nutrients.. With around 450,000 cattle on feed in Queensland, there is close to 500,000 tonnes of manure to be utilised as fertiliser each year... Potassium: K There is more than enough K when manure is used to supply P. Sorghum yielding 5 t/ha, has K removal around 22 kg/ha/yr, which means 170 kg of K in 10 t/ha of manure would last 7 years...

Ground Cover Radio 109 Northern research measures dual purpose profitability.. Dual-purpose winter grains for grazing and cropping are planted to a relatively small area in the northern grain-growing region, but GRDC-funded research has shown the significant profit potential of this versatile system in this region... Grazing fertile, cracking clay soils in northern New South Wales is not widespread due to concerns about the effects of livestock trampling on the soils' physical conditions...

Prior to sowing wheat in April, clods will be collected from the same, GPS located sites and scanned for soil structural properties using tomography and SCAMP. Soil moisture and NDVI will be monitored before a yield map is generated that will be compared to the original LRI map for any relationship between livestock presence and grain yield... The extent of change in porosity in clods collected from 10-20cm depth (the depth at which livestock compaction is typically observed) shows no relationship between Livestock residence and clod porosity (Figure 4)... Livestock residence index and porosity of clods collected from 20 sites ranging from low to high LRI..
