Gardening - Worms to Help Your Garden


Garden Wigglers: Earthworms in Your Backyard (Backyard Bugs)

Putting Worms to Work to Help Your Garden

VOA - July 04, 2011


You can make compost from food waste at home with or without the help of worms. How the worms help is by first eating and processing the food. It comes out the other end of the worm as rich compost.

Kim Gabel from the University of Florida Extension service in Key West suggests using red worms known as red wigglers.

KIM GABEL: "The red wigglers are the best varieties for doing it because they are more of a surface feeder. Because different worms live in different strata, or portions of the earth."

You need a container to hold the waste and the worms. The size of the composting bin depends on how much compost you want to make. You need about a kilogram of worms for each half a kilogram of daily food waste that you add.

Kim Gabel says the bin needs holes so the worms can get air.
KIM GABEL: "The worms do breathe. So that is a very important factor, along with they also like to be in the dark."

So cover the bin to keep out the light.

One thing worms do not like is very high temperatures. Kim Gabel lives in the warm climate of southern Florida. She keeps her worm bin indoors. Unpleasant smells can be prevented by controlling the amount of food waste added to the bin and avoiding meat or bones.

For composting with worms, you need bedding that is moist but not too wet. The amount of water you add will depend on the bedding material you use. Kim Gabel uses newspaper cut into strips about two and a half centimeters wide. Add two handfuls of soil for every half square meter of bedding material and mix well.

Spread the worms over the bedding. The worms will start to wiggle their way down. Remove any worms that remain on top of the bedding after two hours.

When you feed the worms, place the food about two and a half centimeters below the surface of the bedding and cover it.

The worm's waste, or castings, should be ready to use as compost within two to six months.

To remove the compost, you can push it all to one side of the bin. Place new bedding and food on the other side. Within a few weeks the worms will move to the new bedding. Now you can remove the compost and fill the empty space with new bedding.

Genetically-Modified and Organic Crops - Can They Co-Exist?

Can Genetically-Modified and Organic Crops Co-Exist?

USDA promotes co-existence, but opposition remains strong

Opponents of genetically-modified crops - like this maize - are suing the USDA for its recent approval of crops they say are likely to cause contamination in organic fields.
 
In the midst of lawsuits over genetically modified organisms, the U.S. Department of Agriculture is asking, "Can't we all just get along?"
GMO opponents are suing USDA for its recent approval of crops they say are likely to cause contamination in organic fields. USDA wants to bring the opposing parties together to find ways for GMOs, conventional agriculture, and organic farming to co-exist.

For crops such as maize, GMO and organics are already co-exisiting, if imperfectly. The United States raises more maize than any other country in the world, and almost all of it is genetically modified. There has been almost no evidence of health problems or environmental harm from GMO maize. But that does not mean everyone is okay with it.

Opposition

Lynn Clarkson runs Clarkson Grain and Clarkson Soy Products, two companies serving food and animal feed makers. At a recent USDA panel discussion, he described a conversation he had with a tortilla maker.

"I'm in the food world," the tortilla maker told Clarkson. "I can get sued for all kinds of things and I have a conscience. I don't know if this is safe or not, and I don't want to find out."

That was fine with Clarkson. His companies specialize in organic and non-GMO grains. Opposition to GMOs is one of the factors that have made organic products a $25-billion-a-year market in the United States.

Challenge of co-existence

That highlights a major challenge in American agriculture. How can these two profitable but mutually exclusive types of agriculture co-exist, when there are so many ways contamination can happen? Pollen can travel from a GMO field and contaminate a non-GMO crop. Grains can mix in storage, shipping, or processing.

For the most part, the U.S. government has not gotten involved.

"So far, we have operated under a market-driven system," says University of Missouri economist Nicholas Kalaitzandonakes. "And by and large, generally it has worked."

Premium price for organic

It has worked, he says, because customers are willing to pay a premium for organic and non-GMO products to businessmen like Lynn Clarkson who can provide them.

"So if you wish [to have] non-GMO, it's perfectly fine with me," he says. "If you wish organic, or if you wish [to have] a crop raised under a blue moon, and are willing to pay for it, that's acceptable, too."

Clarkson's customers are willing to pay him extra for the steps he has to take to keep GMOs out of his products. That includes making sure that everyone all along the supply chain uses separate or thoroughly cleaned equipment to grow, harvest, transport, store and process his crops.

Contamination inevitable

But the system is not perfect. Some contamination still happens. And Clarkson says many customers accept that.

"If you deal with the tolerance standards out there today, zero is simply not an option," he says.

Even the normally restrictive European Union is considering lifting its zero-tolerance standard for GMO contamination in imported animal feed. Clarkson says many producers aim for no more than one-tenth of one percent contamination.

"Organic means no GMO"

But attorney George Kimbrell with the Center for Food Safety says that is not good enough for many consumers.

"If you talk to organic consumers, for example, for them, organic means no GMO," he says. "It doesn't mean a little bit of GMO in it."

He says the companies that produced and patented GMO crops should be the ones responsible for keeping them out of organic products, not the other way around. Kimbrell says it's hardly a novel legal concept.

"If your bull breaks out of your barn and causes a ruckus [damage] in my field, you are liable for that," he says. "That liability should extend to the owners of these genetically engineered crop patents."

Contamination likely?

Opponents like Kimbrell say some genetically engineered crops are so likely to cause contamination that they should not be introduced anywhere.

But the USDA believes it is possible for these crops to co-exist with non-GMOs. The department recently approved one of them -- alfalfa, and is nearing approval of another, sugar beets.

The Center for Food Safety has sued USDA to try to keep these crops off the market. Those lawsuits are a big part of why USDA has been stepping up its efforts to promote co-existence.

But the lawsuits continue. And comfortable co-existence between supporters and opponents of GMOs is a long way off.
