Annotated bibliography
Sources
Annotated bibliography for electroculture history, copper-rod testing, plant electrophysiology, and active electric-field research.
How This Site Uses Sources
This guide separates source types. Historical books prove that electroculture was proposed and tested; they do not prove modern copper stakes work. Controlled plant trials weigh more than anecdotes. Reviews help map the field, but they are read alongside the methods of the studies they discuss.
Primary Historical Sources
Bertholon, De l'electricite des vegetaux (1783)
The early atmospheric-electricity source associated with Bertholon and the electro-vegetometer. Used here as historical evidence, not modern proof.
Selim Lemstrom, Electricity in Agriculture and Horticulture (1904)
A central electroculture book with reports of crop experiments and electrical treatment apparatus. Useful for understanding the older active-treatment tradition.
USDA Department Bulletin 1379, Electroculture (1926)
A skeptical and practical review of early field and plant-house experiments, including definitions, yield tables, and cautions about field-trial error.
Blackman, Field experiments in electro-culture (1924)
A peer-reviewed primary field-experiment paper from The Journal of Agricultural Science. Used to show that electroculture received formal agronomic attention.
Electricity in agriculture and horticulture
Controlled Evidence And Reviews
Chier, Oakey, Budny, and Lemoine (2025), PLOS One
The most directly relevant source for modern passive copper rods in container gardening. It tested four vegetable crops, three treatments, growth traits, photosynthesis-related measurements, and biomass.
Pohl (1977), Electroculture
A review in Journal of Biological Physics arguing that strong electric fields and small air ions could affect crop production. Useful as a map of the positive historical case.
Schmiedchen, Petri, Driessen, and Bailey (2018)
A systematic review of static electric-field exposure in invertebrates and plants. Useful because it foregrounds methodological flaws and environmental-field context.
Modern Context Sources
Li et al. (2022), Nature Food
A powered triboelectric nanogenerator system that reported faster pea germination and increased pea yield. Cited as active-field context, not proof for passive rods.
Dufour (2026), Comptes Rendus. Mecanique
A modern review connecting Bertholon's electroculture legacy with cold-plasma agriculture, while noting the limits of early experimental dosing and rigor.
Frontiers in Plant Science root signaling review (2017)
Background on plant electrical signals and root-to-shoot communication. Cited to separate real plant electrophysiology from unsupported garden-device claims.
