    Great achievements Loran. Where too next!!?

    How deep is your soil now? Any idea where you hit rock/hardpan/salt/heavy metal layers?

    Our farm used to be temperate mallee eucalyptus woodland 50-100yrs ago with total P (acid digest) 50-100ppm in top 10cm. Now most is around 150ppm, with a target of >300ppm. (Not sure on the calculation to lbs/acre)

    I can see us medium term off the bagged nitrogen but biology cant solubolize P or traces if they never existed. Slow game now I guess with capital applications of rock phosphates and VAM??

    Thanks for your input
