Plenty of interest in the Lucerne variety Pasture Trial Network & @DLFSeedsAU walk this arvo at Eugowra. Will be great to see these locally produced results published in 3 years time
Finishing the last of the quality samples from the Cabonne Pasture Competition, ready to send to lab today. @lawbal44 your two here, ground up, hard to pick the Fescue from the lucerne
Cowra Acid Soils @NSWDPI_Pastures research update & bus tour to Toogong @lawbal44 to see first hand the pasture responses to lime treatments, see you this Friday
Crutching &vaccinating adult ewes today.
Electronic vaccinator has a counter. 246 doses (with a few still in the tube) from the first 250 does packet. I'll take that for the win👍
Phalaris is growing today at 450m elevation near Cudal. Sheep only moved from this pdk last week. Sun shining soil moisture soil fertility = pasture growth. The formulae that drives economic growth in regional NSW.
@theGRDC Canola establishment field walk tomorrow at Canowindra.
Time: 10am
Location: Woodlands (refer to flyer)
Rainout shelters have provided some great insights into dry sowing and the critical moist% required for establishment. Hope to see you there. @CSIRO@NSW_AGRONOMY
Using shelters & irrigation to adjust seedbed moisture & to ensure dry conditions post sowing.
Questions are: what’s the critical moist % to establish canola, & can seed be placed deeper if surface too dry? Really looking foward to these @theGRDC results👍@CSIRO@NSW_AGRONOMY
Excellent morning for establishment counts at the acid soil research site Toogong. 7 pH profiles sown to either Lucerne chicory or tall fescue mixes with serradella and gland clover @meatlivestock@PhilCranney@rickchayes @DrJasonCondon
Col McMaster showing the @theGRDC National canola establishment team the trials near Canowindra - all things seeding/establishment. Off to Condo next. Depth, seed size, press wheels, fertiliser, soil water at sowing, disc vs Tyne. Great data from NSW red acidic loams.
Great point Matt, as each year passes that we don’t look at replacement for P & N in grain off-take, we limit future profits (cost is simply deferred).
This can happen quickly or more slowing depending on the initial starting P & N bank from organic and inorganic sources.
To recover from net mining of these nutrients it will requires (i) the addition of annual P & N that matches off-take in grain plus (ii) a surplus amount of P & N to establish a soil fertility baseline that doesn’t limit yield in the years of decile 7 or greater rainfall. Noting that these are the big profit years.
Maintaining the natural capacity of soils which includes nutrients, is a focus for #RiskWise@theGRDC in N-NSW and QLD with @gentry_jayne@dr_dirt_oz@andrewErbacher and @HenryBasker.
Anyone can mine nutrient resources short term- this probably not a long term approach ? When depleted , how are reserves topped up ? This photo is P vs No P in low colwell situations. Can get ugly. Hope the right messages are getting out
With permission, sharing a mates pics on a farm he just bought.
First crop after previous owner had 60 years of no fert and running livestock.
Below and right are where fert on airseeder stopped.
Dramatic demonstration of the importance of fertiliser on our soils productivity.
