US Patent 8017061 - Plant and soil treatment using nanotechnology

http://www.freepatentsonline.com/8017061.html

Plants and soil are traditionally provided with nutrients or pesticides using liquid spray, solid powder, or gas dispensing. This patent teaches how nanopolymer fibers can also provide delivery of nutrients or pesticides while being less susceptible to rain and wind than the traditional delivery methods. Claim 1 reads: 

1. Method for the output of nanoscaled polymer fibers and tubes or hollow fibers as carriers for agricultural or agriculturally useful active substances, said carriers being in a state loaded or unloaded with such active substances, wherein the output occurs through use of the procedure of electrospinning and wherein the farmland or/and plants found thereon or/and seeds found thereon or therein, or seeds without surrounding soil are used as counter electrodes.
