Rensselaer Semi-Weekly Republican, Volume 38, Number 85, Rensselaer, Jasper County, 20 July 1906 — Electricity Stimulated Vegetables. [ARTICLE]

Electricity Stimulated Vegetables.

That it is practicable for any farmer or gardener to advance the growth and quality of table vegetables through the direct application of electric current, and ‘with very little expense, is in process,of demonstration by Warren 11. Rawson of Boston. Heretofore this has been done by the use of electric lights. Mr. Rawson found that if a copper plate was sunk in the loam at one end of the bed aud connected by nn overhead wire, with a zinc .plate in the soil at the other end of the bed, a measurable current of electricity was set up from chemical action of the ammonia and other salts upon the zinc plate. He found that lettuce thus treated was ready for market a week ahead of that in the ordinary, and the heads‘were also larger.
