Good day to look where the water is in the profile post ripping and different inclusion methods as part of @GRDCSouth Sandy Soil II investment at Crystal Brook with @TrengoveSam @AndrewSarge @Dr_Soil_Data Still deciding if new soil pit digger is useful!!

Great to see some On-Farm Experimentation come to life across variable landscapes! @TrengoveSam @Moodie_ag @McbeathTherese @kentonp_ag @GRDCSouth

A project investigating the economics of ameliorating soil constraints in the northern region with @unisquas @UniNewEngland @DAFQld @nswdpi has provided a new manual for dispersive soil management. Read more: https://t.co/qJRecNva0m Download the manual: https://t.co/Y4Gak90hSC

Next phase capturing Pampas FS site happening. @DLAntille running suction plates for #soilwater, helping @lindsaywbell and I get some #spatial analysis going. Thanks @data_farming for #EM38 map. @DAFQld & @CSIRO + @GRDCNorth #farmingsystemsnorth

@DAFQld out harvesting #soilconstraints Millmerran. Two days soil coring coming up to finalise site for this year. Early numbers 50% variation in yields. @gentry_jayne @Dr_Soil_Data @GRDCNorth @ILSE_USQ

Who said we don't have have acidic-compacted-dispersive subsoils in QLD? Will be interesting to see how yield response changes as the #soilconstraints vary from one end of the paddock to the other. @dr_dirt_oz @mclean_bennett @gentry_jayne @theGRDC @ILSE_USQ @MickFreeman10

A great commercial prototype thanks to @TTQAgriculture. Amelioration of #soilcontraints is showing some promising results! Let’s improve our soil assets and get this rig running on more farms! @ILSE_USQ #agtech @AgChatOZ @abclandline

All from the same paddock!
Toowoomba has turned the weather on, so into the lab for some textural analysis. And new cylinders make those colours pop! Fine scale texture is an integral attribute towards mapping Soil Water Characteristic on a fine scale. #PhD #soilscience

Great day to check out some tech and have a chat about equipment we can use to manage our more difficult subsoil constraints. #deepripping #subsoilgypsum
Make sure you get your tickets! We will be there and we are hoping to bring some new stuff along. And some results of the recent trials being supervised by @Dr_Soil_Data Will also be a chance for you to have some input into some of our new concept stuff!

Great to have this running around the country side implementing #soilconstrains trials. Ameliorating compaction whilst treating dispersive subsoils with #gypsum to increased water holding capacity. Keep an eye out for the rig as it runs around! @TTQAgriculture @ILSE_USQ @AgChatOZ

Great to chat about some of our initial #soilconstraints results and discuss what it means for on-farm decision making
Fixing subsoil sodicity - what is the research showing? Stirling Roberton @Dr_Soil_Data filling us in on the local research at #Meandarra #GRDCUpdates Paper:

Good to have the 8RX 370 on site thanks to @VanderfieldAU . Able to achieve a 600 mm ripping depth for the #soilconstraints trial with @MickFreeman10.

Another great trial in investigating #soilconstraints. Figuring out which areas of the paddock will have the best Return-On-Investment for #soilamelioration. @theGRDC @MickFreeman10 @ILSE_USQ

Great to have this out on farm implementing some of the trials we’ve designed. More info to come!
We pride ourselves on the principle of custom building rigs. And farmers often test that out 😀 But when scientists walk into a room with a plan to put gypsum in at great depths, then it ends being a whole new level of custom build...! Day one of the trials today 👍

Benchmarking your #soilconstraints is the first step in designing tailored soil amelioration plans! @CottonResearch @GRDCNorth @ILSE_USQ

What #soilcontraints will be in your Xmas stockings this year? The #USQ team giving Santa a run for his money delivering soil sampling joy in Bowen, Townsville, Millmerran, Moree, Trangie and Forbes over the next 2 weeks. @ILSE_USQ @theGRDC @CottonResearch
