Recordings of presentations from IFS Conferences

From 2015 onwards the presentations and follow up question and answer sessions at our Conferences have been audio recorded and then matched to the presentation charts. These recordings are available to view online (but cannot be downloaded) at any convenient time.  They provide an opportunity to hear and see what was presented, at a pace to suit yourself.

These recordings are free to Members, but a small charge will be made to non-members, to cover the cost of producing the recordings. This charge is £9.50 for the first recording chosen, and £5 for all subsequent ones ordered at the same time. The total cost of an order will be shown at the bottom of this page. (Note that if two recordings are bought as two separate orders, both will be charged at £9.50.)

To access these recordings, tick the box against those you wish to view.  When you have ticked all those you are interested in, click the Checkout button.  This will take you to the online shop.  Here you will be asked to pay, in the same way as for Proceedings.

The IFS Secretary will then e-mail you the link and password to view the recording(s) that you have ordered.  No money will be taken from the credit cards of IFS Members.

Complete these boxes before going to the Checkout.

This checkout form generates a database entry which is only stored so we can process your order. Your details are not used for marketing purposes. Your information is never shared with any organisation outside of International Fertiliser Society.
