soil depth

Catalogue: GRDC Updates (West)
The relative effectiveness was calculated at the effectiveness of N at a depth compared with the effectiveness of N in the top-soil (0-0.2 m layer)... (A assuming Bulk density of 1.5), B % of sites measured to that depth not of the 474 cores).. The trials necessarily included whatever deep soil N the crops could access and so the responses will be weighted by that contribution from deep N. For tools such as Yield Prophet , the N at depth is usually measured and included in the model the roots for most of the soils in Yield Prophet are set to unconstrained growth...

Potassium was applied at rates between zero and 100 kg/ha IBS and banded in the forms of MOP and compound NPK product (Vigour)... Key messages - There were no significant differences between K sources or rates at this trial, despite soil test model predictions of high K response - Canola did not respond to high P application at this site in the absence of Nitrogen - The site was highly N responsive, although the N use efficiency suggests leaching was moderate... Available water capacity computed for each of the specified depth increments..

Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...
