Nope, haven't heard of anybody looking at this at BCG, Adon.
I think that BCG is just looking at survival techniques for the Mallee farm area at the moment as even the southern areas are not getting much attention from BCG.
The Nhill members of which there are quite a few haven't got any attention at all.
I'm trying to get a name of a very quiet lady soil biologist from DSE who keeps a low profile but apparently is a wealth of knowledge on soils.
Will check and pass the name on if and when I get it.
Apparently she has researched items like retaining standing stubble against slashing stubble down and found that below an 18' rainfall there is absolutely no benefit to the soil in keeping stubbles standing as the microbiological activity simply does not exist in sufficient amounts to break down standing and dry stubble straw.
Slashed stubble in a less than 18 inch rainfall allows enough moisture to be in contact with the stubble to get the microbes active and break down the stubble and to incorporate the products of stubble breakdown back into the soil.
