Salt Free Farming- Andrea Tholen

Here is a link to a YouTube video that I thought was really interesting on Salt Free Farming.

The video talks about the Associate Professor Greg Leslie genuis idea of salt free farming and how it can really help farmers out during droughts. He is from UNSW which is a chemical and engineering school in Austrailia and it was published in 2008, the video says that they hope to have the idea out to many people in a few years. He plans to take water from the ocean and extract the salt from the water so plants will be able to get what they need from it without actually getting the salt (reverse osmosis). They have tested it on common market crops and it proves to be sucessful thus far. This idea would save many farmers from the dry years and be an alternative way for them to water their plants without having to rely on the weather and enviorment.
