Greenhouse benefits: When growing seedlings (tomatoes, bell peppers and other types), it is
important to have an environment that will not stress the growth of the newly planted seedlings. Harsh chemicals have a negative
effect on the growth along with the algae growth that will transmit E.coli and other unwanted pests from one tray to another.
Agri Ionization Systems equipment will deliver a copper level that
can be taken up through the roots as a nutrient while killing the algae on the trays, leaves, benches and walls. Keep
in mind that while the ionization unit is running, it is also maintaining water quality and irrigation lines free
of scale/bioslimes. This means no clogging and no stress to the young seedlings. |

Growing specialty
herbs is a science and an art.
Agri Ionization Systems, Inc. has developed a program for these specialty growers.
Positive charged copper ions applied when irrigating continually protect the crop from E.coli, Pythium, Botrytis, Brown spot,
Algae etc.
The copper ions will also descale and maintain your irrigation system from scaling in the future.
Notice the lack of algae in the pictures below.

Flats can grow algae that can spread pathogens. Agri Ionization Systems can prevent this problem.

STUDIES IN IONIZATION DISINFECTION
Abstract
TITLE: Evidence for the Role of Copper in the Injury Process of Coliform Bacteria in Drinking Water
AUTHORS: Domek MJ, LeChevallier MW, Cameron SC, and McFeters GA
PUBLICATION REF: Applied and Enviromental Microbiology
48: 289-293, 1984
PURPOSE OF STUDY:
Although high concentrations of metals are known to cause injury to coliform
bacteria, little is known about these effects at the concentrations of metals commonly found in drinking water. This study
investigates the effect of low levels of copper on coliform bacteria, specifically Escherichia coli (E. coli.) cells, in samples
of typical drinking water.
MATERIALS AND METHODS:
Copper concentrations were determined by the differential
pulse polarographic method in 44 drinking water samples drawn from two drinking systems in which chlorine residuals were low.
Oxygen uptake levels were also determined.
RESULTS:
In the 44 samples tested, copper concentrations ranged
from a minimum of 0.007 mg/liter to a maximum of 0.540 mg/liter with a mean of 0.117 mg/liter. A concentration of 0.05 mg/liter
produced greater than 90% injury to the E. coli population within 2 days and over 99.5% after 5 days. A higher concentration
(0.25 mg/liter) caused injury at a faster rate. Increasing temperature also accelerated the rate of copper-induced injury.
Copper alone caused as much injury as a mixture of copper, lead, and cadmium.
CONCLUSIONS:
Exposure to copper
has been shown to cause damage to E. coli in drinking water. Since copper from both natural and man-made sources may be present
in drinking water, the effect of copper on coliform bacteria should be considered when testing public water supplies. Injury
due to sublethal amounts of copper can lead to underestimation of the bacterial count when m-Endo agar rather than the more
sensitive m-T7 medium is used.
