  • Salt Contaminated Landscape

    Executive Summary

    Throughout much of the world, salt is used to melt snow and ice on roadways, sidewalks, concourses, etc. Although salt is an effective, low cost solution to melt snow and ice, it can be damaging to plants, trees and grass along roads and thoroughfares. It can also be costly for government and private organizations to repair and replace the damaged landscape. There are very few low cost prevention techniques for salt contaminated soil. Floris and NutraHume were tested and proven to reduce the adverse effects of salt toxicity on plant material of any kind.

    In 1998, an extensive study was sponsored by the government and conducted in Moscow, Russia by the Moscow Engineering and Landscaping Company to develop and test ways to eliminate the adverse effects of salt on landscaping along roadways. Throughout the city, an estimated 100,000 trees died annually due to salt toxicity from road salting.

    Test plots were selected among some out of the worst affected areas. The test plots were tested for salt and high levels of salt were detected. None of the trees showed signs of budding or leaf-out prior to treatment. In May some trees in each plot were treated with Floris (diluted 1:1200 with water) every 14 days. Other trees were left untreated and used as controls. The dilution was applied to the base of the trees and bushes in a drench method.

    Result: After 42 days, the treated trees started to leaf-out and regained normal, healthy growth. The untreated trees did not show signs of leaf-out or recovery, many of which died.
