Currently, fertilizer is made using natural gas (steam reforming of methane to generate hydrogen to feed into the Haber process)-- but with the new advances (http://www.greencarcongress.com/2008/07/researchers-at.html), it should be possible to generate that hydrogen directly from water using sunlight; feed the hydrogen into the Haber process (energy expensive, true, but doable), and then you have your ammonia, convert half of that to nitrate, and there you have your ammonium nitrate fertilizer, which currently accounts for about 1/2 of all agricultral fossil fuel use.
