Another issue is that organic fertilizers, in particular, tend to release their nutrients more slowly than chemical ones. Speedier release of nutrients, leading to a quick "greening" of your grass, is one of the main selling points of artificial fertilizers.

So it makes sense to change lawn care habits to do less damage to the environment. However, in a world where the goal is to produce a green carpet in the Nike Football Boots 1999 minimum of time, that can be easier said than done.
Other quick steps, she said, are to fertilize in the spring and fall but not in the summer, to use a mulching mower that leaves clippings on the lawn so that their contained nutrients aren't removed, and to make sure that you use only what your lawn needs.
"Promoting the health of the soil that's the basic premise of organic lawn care or organic gardening of any kind. If you have good biological diversity, turf grows well," she said.
more pollution per hour of operation than cars or trucks and the use of fertilizer or pesticide.
Despite such concerns, Hagen says the benefits for the environment can be large, and over time it can benefit your lawn.
"My biggest piece of advice to people is do it slowly," she said. "If you go from conventional commercial lawn care and switch immediately over to organic, your lawn is going to decline."
However, most organic fertilizers contain phosphorus and potassium and most soil in New Hampshire has plenty of phosphorus already. As a result, Hagen said, using extra organic fertilizer to meet nitrogen markers can produce phosphorus run off into adjacent waterways just the sort of thing that organic lawn care tries to avoid.
By acreage, grass is one of the nation's four biggest crops, along with corn, wheat and soybeans. Those grassy areas, including golf courses, parks, cemeteries and ballfields as well as yards receive an Soccer Shoes With Sock
Consider phosphorus and nitrogen.
"Conventional is released in six weeks or less, and some organics take up to a year to release, you've got nothing going in the middle," she said.
of what you're doing, and that's more time consuming," said Hagen.
That decline will occur because the nutrients from the synthetic fertilizer will have been used up before the natural nutrients begin to appear.

Aside from the ancillary damage done to insect and wildlife, too much of this material ends up in waterways, where it can cause algae blooms, fish die off and other bad events.
Even if people don't want to go organic, she added, they can reduce their environmental impact by shrinking the area planted with grass, which requires mowing lawn mowers usually produce far Nike Soccer Shoes Silver
estimated 70 million tons of fertilizer and 70 million pounds of pesticides, averaging roughly 10 times the amount of pesticide per acre as used on food crops.
"People have to be willing to take the time. Any time you're trying to grow something and not use our traditional fertilizers and/or weed killers, you have to actually understand the biology Football Boots Girls
"Most organic turf fertilizer have 8 percent or less nitrogen in them," said Hagen. To reach recommended nitrogen levels involves using "three to four times as much organic fertilizer" as chemical fertizlier.
"Instead of mindlessly buying that four step program, check does you lawn have crabgrass? Do you need to buy that combined (fertilizer and weed killer)?" she said. "Don't buy combined use products unless you need them."
"I didn't even have a talk about organic lawns until 2008. Now I go out and deliver that talk several times each spring," said Hagen, an educator with the UNH Cooperative Extension.
As a result, for at least a year, she said, people should use fertilizers that have a mix of both types to wean their lawns off the quick hit nutrients.
