Trial details


The key aim of this trial was to compare soil pH change to depth; with two different sources of lime (lime sand and farmers chalk lime).

Key messages
  • A unique trial design (double up of each plot) was designed to allow destructive biomass sampling, and grain yield measurement
  • This trial site was primarily used in a ‘screening function’- to evaluate any negative impact of lime of a variety of different legumes which was considered to be happening during the mid 1990’s. The key concern was to investigate if manganese deficiency was induced by liming
  • The trial was sown to lupins in 1994, wheat in 1995.  Data not available
  • Yield responses (negative) were apparently not noted in the early years following establishment of the trial.  Positive yield response did occur, several years post trial establishment
  • The double up design allowed comparison of lime sources on many different species.  For example, in 1996, narrow leaf and yellow lupins were compared.  No data available
  • In 1997 the trial was sown to wheat, no yield responses reported
  • In 1998, the trial was sown to a diverse mix of new pasture legumes that were at various stages of evaluation prior to commercial release.  Some of the material screened, that subsequently was commercialised included Cadiz French serradella, Santorini and Charano yellow serradella, Casbah Biserrula, Prima gland clover and finally Bartolo bladder clover.  The primary focus of this work was to assess any negative impacts of lime on legumes.  No negative impacts reported.
  • The inclusion of this trial into this sampling regime, was primarily because of the known (high rates) of lime subsequently applied by the cooperating farmer, and the focus to see if these high rates had changed soil pH deeper in the profile, which did not occur initially.
