Dr Cameron Grant and Emeritus Professor Pieter Groenevelt seminar

Important information for event attendees and external visitors

coronavirus (COVID-19)In light of the most recent advice from the UK Government about stopping non-essential travel and increasing social distancing, most of our events have been rescheduled or moved to an online format.

Our sites have been placed on a restricted access condition, which means that only staff who are doing essential work can get access. All other colleagues will be working from home or staying at home even if they are unable to work remotely.

We have excellent and free to use video conference and conference call systems and are happy to make these facilities available to help you engage with us. Meetings are taking place via video conference with participants joining individually from their own locations; check with the relevant member of staff for advice.

As the situation is constantly changing, please check the UK Government and NHS websites for the latest advice and updates.

If you have any questions or concerns, please email events@hutton.ac.uk.

Cameron Grant and Pieter Groenevelt giving a seminar

Dr Cameron Grant, University of Adelaide, South Australia and Emeritus Professor Pieter Groenevelt, University of Guelph, Canada will deliver this joint seminar entitled "Plant available water: What must happen to make its accurate prediction more than just a Clayton’s dream?".

Scottish barley yields are down this year despite there being no shortage of soil water – in fact, the excessive soil water probably contributed to the lower yields. By contrast, Glyn Bengough and colleagues have recently shown that many Scottish soils are so hard that plant roots struggle to penetrate them to extract water and nutrients.

In the sandy, drought-stricken soils of central North America, maize yields have been disastrous this year, particularly on the sandier soils, where evaporative demand has outstripped the ability of the soil to transport water to root surfaces through the growing season. Furthermore, many crops around the world grow on soils that experience multiple physical limitations such as salinity, waterlogging, compaction, hardness, and low hydraulic conductivity – some of these limitations also interact to reduce plant water extraction.

To accurately predict crop yield potential based on soil water requires us to integrate the limiting soil factors for different plants under different soil and environmental conditions. The ultimate model for this purpose, however, has been elusive to date and scientists might well ask whether seeking such a model is simply another Clayton’s dream (i.e. the dream that will never eventuate).

Pieter Groenevelt and Cameron Grant have worked together over a period of 30 years on several applied problems in soil physics. In their seminar, they will present ideas to help integrate the soil and plant factors that dictate plant available water and they will seek your advice on the best plant-response factors for evaluating their models.

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
