Minister, we shouldn't look back at ideas that were being discussed about 30 years ago for a solution to water pollution. We have to look to the future by embracing technology to make far more accurate choices around land management. As you know, there are examples of innovative projects being carried out as we speak, where farmers and researchers are working together to devise a far more sophisticated way of putting nutrient management plans in place. 

You will know that Gelli Aur college farm has recently completed a very successful pilot project, called, Taclo'r Tywi—tackling the Tywi—in a part of Wales that has notoriously been a black spot for river pollution, using weather stations on farms to measure soil temperature, leaf moisture, wind direction and rainfall. Now, this provides real-time data on a phone app within seconds, using a red, amber, green system that will allow farmers to make on-field decisions around slurry spreading, pesticide spraying or harvesting. This is far more scientific than farming by calendar, which is both impractical and outdated.
