Dealing with acid soils at deeper depths
The Land Australia, Other, 10/05/2021, Bob Freebairn
Jason Condon and Helen Burns check pH after lime application in a soil profile. Insufficient mixing of lime into the soil profile is seeing an elevated pH on the top 0-5cm layer but a continuation of acidic problems in the 5 to 15cm soil band. […] These views are emphasised in a recent paper published in CSIRO journal Soil Research titled “The extent, significance and amelioration of subsurface acidity in southern NSW” (https://doi.org/10.1071/SR20079), by Wagga Wagga NSW Department of Primary Industries (DPI) researchers and soils experts Jason Condon, Helen Burns, and Guangdi Li.
