This research identified the plant traits most likely to determine differences in external critical phosphorus (P) requirements (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of pasture legume species. Understanding trait differences that affect critical P requirements of pasture legumes is important in providing confidence around field differences in external critical P requirement.

In 2012 the UNFS attempted to validate this early work conducted by the CSIRO. Seed of a long season variety Eaglehawk was sourced. This variety is Prime Hard Quality in NSW and so would be AH in SA.The aim was to conduct a time of sowing trial using three varieties at three times of sowing:- an early maturing variety (Axe), mid season maturing (Frame) and late maturing (Eaglehawk). Ideally the three sowing times were to be 1) mid April 2) early to mid May and 3) early to mid June.

To report on the use of crop sensors as an aid for nitrogen decisions.

There are a range of machinery options that can provide different levels of lime incorporation such as spading. However, research to date on rotary spaders has shown soil/amendment mixing is not uniform due to the cyclical process, and the mixing quality reduces significantly at faster speed (Ucgul et al. 2019). This trial aimed to understand how the uniformity of soil-lime mixing by spading affected crop response and soil pH.
