Both lime and gypsum applied to acidic soil have led to long term improvement in wheat grain yield. Application of lime increases soil solution pH (pHSoln) and while the application of gypsum increases soil solution sulphate (SSoln)....

The development and impact of disease is influenced by several factors including environmental conditions, pathogen levels, crop and variety choice, and management decisions including nitrogen application. There was no significant interaction between variety and nutrition on crown rot index (incidence x severity) in wheat or barley. The study by C...

The weather API sources up-to-date weather data and flexible data summaries, increasing the number of maps produced. Spatial coverage has improved with the addition of 175 stations, improving understanding of current climate conditions, and their potential impact on the agriculture industry....

Mitigation strategies (paired-row sowing, near-row sowing, and wetting agents) provide cheap management options, but must be implemented every year and need to be targeted at responsive soils and situations. Paired and near-row sowing typically increased early emergence by 50%, but had smaller and more variable effects on grain yield. Banded soil w...

Around 24% extra load is expected on tractors when pulling deep rippers with inclusion plates on sandy loam soils. Use of inclusion plates gave an estimated extra fuel cost of $3.7/ha (3.7 L/ha) and work rate was reduced by 24% while initial measurements suggest loosening around 30% more soil volume compared with no inclusion plates. These data wil...

Both barley varieties out yielded wheat by approximately 1000kg/ha in all treatments Barley yields responded to the highest rate of early post emergent nitrogen (75kgN/ha) with wheat yields plateauing at the 50kgN/ha rate Ryegrass biomass was two to three times higher in wheat than barley, and this may have significantly reduced wheat yield...
