 Chemical analysis today is very complex and time-consuming. The IBM AgroPad is paper-based analysis for agriculture. You deposit a liquid on the cart, just a droplet of the sample can be water, can be a soil extract. And then you flip the cart around, you essentially use a smartphone application to take a snapshot. So when you plant corn or tomatoes, there is always what we call the genetic potential. How much you can produce in that parcel of land? So what we want to do is to provide the simple device that they can test the soil and then they can correct the soil to maximize the production of what they want to produce.
