No, there are no storage costs. Storage would be your own cost. What it speaks to is the farmer's right, in your case the ability to keep seed over to be used again the following year, or three years down the road. It really doesn't specify. You would sign a contractual agreement with the seed owner to either pay the intellectual property rights up front, as most farmers will probably do, but there's also the ability not to sign that contract, but to sign one that says you will pay the intellectual property on the seed that you sell. There will be a different value for that, but it's something you would work out with the seed grower.
