US Patent 7494526 - Nanoparticle plant food


Foliar feeding is a plant feeding methodology in which nutrients are directly applied to the leaves rather than to the ground or dirt in which the plant is rooted. This patent from inventor Edward Yavitz teaches how to use nanoencapsulation to improve the process. Claim 18 reads:

18. A method for treatment or feeding of plants, comprising:

encapsulating a plant supportive material in particles having diametrical dimensions of less than about 1000 nanometers to facilitate foliar application of the plant supportive material; and

applying the particles to plants.
