Fertilizer in Garden
WEDNESDAY, Aug. 26 (HealthDay News) -- Banning or restricting the use of certain types of lawn fertilizers can improve water quality in nearby lakes and streams, new research shows.
Rain and runoff can cause lawn fertilizers that contain phosphorous to leach from the soil into waterways, killing fish, causing foul-smelling algae blooms and disrupting the marine ecosystem.
As awareness of the problems has increased, municipal and county governments around the nation have prohibited or restricted the use of the fertilizers. Some ban their use outright, while others limit usage to the first year the lawn has been planted or to phosphorous-deficient soil.
To determine the effectiveness of the legislation, researchers analyzed water samples from the Huron River, which flows through southeast Michigan. In 2006, nearby Ann Arbor, Mich., limited the use of phosphorus-containing fertilizers.
The study found that phosphorus levels dropped 28 percent in the three years after the ordinance took effect.
Southeast Michigan soil tends to have adequate phosphorus, researchers noted, making fertilizing lawns with the nutrient unnecessary in most cases.
Until this study, there was little scientific research confirming that fertilizer restrictions are an effective means of protecting waterways from damaging runoff, John Lehman, a professor of ecology and evolutionary biology at the University of Michigan, said in a news release from the school.
"It's one of those things where political organizations take the action because they believe it's the environmentally conscious thing to do, but there's been no evidence offered in peer-reviewed literature that these ordinances actually have a salutary effect," Lehman said.
The study was published in the Aug. 14 online issue of Lake and Reservoir Management.
The U.S. Environmental Protection Agency has more on the impact of fertilizers containing phosphorus.

Fertigator Fertilizers Bringing the Green Back To LawnsAuthor: Richard Gilliland
Fertigator fertilizer is a specially made blend that is designed to complement the Fertigator irrigation system. This automatic fertilizer injection system attaches to an in-ground sprinkler and then feeds your lawn every time you water. The Fertigator Company manufactures a Feeder home edition, for small to medium sized products, and a Pro edition for larger jobs.
The great thing about a Fertigator fertilizer system is that you can “spoon feed” your lawn gradually, which is a far better way to oversee plant nutrition than using traditional fertilizer. Traditional fertilizer is chemical-based; this process also pours too many nutrients at once, which results in overfeeding (since plants rapidly take in these nutrients) and then a period of starvation. Unlike human beings, (or at least some human beings) plants do not know how to proportion their meals. There is no Jenny Craig program for plants!
This smarter irrigation process is nothing new—in fact “fertigation” has been around for well over three decades and has permeated numerous industries besides agriculture. The Fertigator fertilizer offered for these irrigation systems include FertiGro TLC with GatorGuard, which is Total Lawn Care designed for year-round use; FertiGro TSC with GatorGuard, which is Total Summer Care Fertilizer with lower nitrogen and extra iron (which helps plants form a darker green color and slows down rapid growth) and FertiGro TGC with GatorGuard, which is for Total Garden Care Fertilizer, which has extra phosphorous and essential micro-nutrients. All of these formulas contain GatorGuard, a special concoction that deters insect and rodent pests. However, unlike most chemical pesticides, this pest-repellant is completely natural and not harmful to plants. The ingredient known as Enhance Bio-Stimulant enriches the soil and allows for maximum growth potential.
The Fertigator fertilizer company advises users not to use regular organic fertilizer for a Fertigator fertilizer system. This is because the special concoction provides a more gradual release than chemical fertilizers. The timeline is important here. Failure to use the right fertilizer and according to the system could result in damage to the plants, damage to the system and could also void any warranty.
You may be wondering how exactly a Fertigator fertilizer system is healthy for the environment and how, specifically, it can avoid contamination of the water-supply, which is always an issue with traditional irrigation. Because it reduces run-off, which eventually combines with the drinking water supply, a Fertigator system minimizes the risk of water contamination. In this operation fertilizer is being injected into the water stream. Additionally, a backflow preventer stops any liquid that contains fertilizer from migrating back into the water line. You see, the Fertigator does not actually increase the pressure in the system; so it should only need a pressure vacuum break backflow preventer.
If you want to see more greenery and a higher quality of plant life then invest in organic materials and in a Fertigator fertilizer system. You can reduce pollution, increase soil quality and enjoy a far more fruitful garden or landscape. The Fertigator is modern irrigation at its best.
