This is WA field based research project between 1994 and 2023 and focused on innovative approaches to managing subsoil acidity in the Western Region - Data and file overview: The data includes: Soil pH, EC and All and other chemical analysis, Soil compaction, Root growth, N, P, K, S, N, Ca, Mg, Mo, Mn and Cu concentrations, Plant biomass, Grain Yield (Maturity, total weight, grain weight, head number), Soil sampling by depth, 20 pogos per plot, number of plants, plant tissue testing for micronutrients, plant maturity - height, tiller counts, lodging scores, NDVI of crop. - Methodological information: Before seeding collect one soil profile from each plot at 0-5, 5-10, 10-15, 15-20, 20-30 and 30-40 cm depths. Collect at least 3 replicates of soil samples for each depth from each plot and combined them; measure pH, EC and Al and other chemical analyses (e.g. exchangeable cations (no prewash), exchangeable acidity, organic carbon, Colwell P and K particle size distribution etc). Collect 20 pogos per plot. Analyse samples for pH, P, K, S and N. Laboratory and analysis package to be advised. Crop establishment • 1 to 3 weeks after sowing: count number of plants in 3 rows x 2m in each plot. Tissue test for micronutrient status • tissue testing (young leaves) for micronutrients at 10 weeks after seeding; collect samples from selected treatments (no ameliorants, highest ameliorants, highest combinations). If deficiency is detected apply a foliar micronutrient product Z65 biomass cuts and chemical analysis. • Cut 3 rows x 2m in each plot. Dry shoots for 48 hours in plant oven and weigh. Grind whole samples through shredder and then grind with a fine grinder. Store finely-ground sample in a plastic container and send sub-samples to CSBP for ICP+N. Finely ground samples retained until completion of trial in 2021. Grain yield components: physiological maturity • Cut 3 rows x 2m in each plot. Measure total weight, grain weight, head number. NIR for grain protein for harvester grain samples Machine harvest all plots and subsample (~2 kg) for grain quality analysis. From subsample measure 1000 grain weight. Store 100g subsample for future analysis (ash alkalinity). Conduct EPP surveillance if required for in-crop EPPs when harvesting sites and report to Grain Biosecurity officer. Conduct surveillance for in-crop EPPs if required when visiting sites to do measurements and report to Grain Biosecurity officer. - Environmental/experimental conditions Further information from the trial-site each year include: soil type, weather conditions, presence of any other chemicals in the soil, and the type of vegetation present - Data specific information: Summaries of these results are the GRDC and DPIRD websites
