Soil pH change over time and the outcomes of a farmer led lime trial locations

To assess a previous soil pH monitoring site, sampled 14 years prior, and a farmer led onfarm lime trial was conducted west of Condobolin NSW.

Key messages
  • Visually the impacts of Lime may not be seen, but the benefits of Lime are evident when comparing
    Limed areas plant biomass and yield with that of unLimed areas.
  • Application of Lime is shown to halt subsoil acidification which is costly to address and will impact upon future sustainability and productivity of an agricultural enterprise.
  • Appropriate rates of Lime are shown to increases yield
