Lime – A UGA Extension Article

Lime

Lime is a very important part of having healthy soil where we live. Knowing how much to apply and where to apply are very important considerations to effectively use lime. Let’s talk about what lime does, why you need it, how much to apply, and how to apply it.

There are a couple of different types of lime that you can purchase. Ag lime is a very common type. It is made up of calcium, carbon, and oxygen. Ag lime will do a very good job of raising the pH in your soil. Dolomitic lime also raises the pH level of soil, but it has magnesium in it as well. If your soil is deficient in magnesium, dolomitic lime is a good option to raise the soil pH, and to increase the amount of magnesium in your soil.

When you get to the bottom of it lime raises the pH in soil. If you recall from chemistry class, pH is basically a measure of the free hydrogen ions in a substance. In this case that substance is soil. pH is a scale that goes from 1 – 14. Numbers below 7 are acidic and numbers above 7 are basic. 7 is neutral. Our soil is going to be naturally acidic. I’ve seen soil reports with pH ranging from 4.5 – 5.5. Most plants like to have a pH of 6 – 6.5. The past couple of weeks I’ve been talking about fertilizers. pH is very important because it impacts how available the nutrients are to plants to be able to take them up. If the pH is low, then most plants won’t be able to grow because they can’t utilize the nutrients that are in the soil.

There’s no way to accurately know how much lime you need to add with doing a soil test first. A soil test will make a recommendation for how much lime you should add based on your pH. It is possible to add too much lime. If you add lime year after year with looking at a soil test as a guide you may end up over liming your land. This can lead to a pH that is too high. You can run into similar issues as with a pH that is too low. A high pH is not common around here unless you’ve over applied lime. In the western half of the country soils naturally have a high pH.

In small areas lime can be applied with a push spreader. You want the lime to make as much contact with the soil as possible, so it may take a few days to water it in. Lime does not dissolve very well in water so it may take a while for the lime to take full effect. Lime can be bought in powder form or pelletized. Both work well, but the pelletized may make less of a mess. There is also liquid lime. Liquid lime can be effective, but it will take more product because it has been diluted down. Larger areas such as a pasture may need a spreader truck to apply the lime evenly and efficiently.

Important! Test Your Home For Radon

Health, Outdoors, TeamFYNSports

Radon is an invisible, odorless gas that causes lung cancer. Every 25 minutes someone dies from radon induced lung cancer, making it the second leading cause of lung cancer. During Radon Action Month this January, UGA experts are advising you to test your home for radon gas. I’d like to talk about what this dangerous gas is, how you can find out if you have it, and what you can do to reduce the radon in your house to a safe level.

When uranium, which occurs naturally in Georgia soil and rock, breaks down, it produces radon gas. Radon is a heavy gas which seeps into homes from the ground and concentrates in the lower levels of a house. Radon can be present in any home, regardless of the age or type of home. The U.S. Environmental Protection Agency (EPA) estimates that about 6.7% of homes nationwide have elevated levels of radon gas; however, in some counties the levels are higher. Homes in north Georgia can have high levels of radon. In Union County, between March 2003 and July 2017, about 46.5% of the homes tested had elevated levels of radon. In Towns County it was 33.1%. An elevated level of radon is anything at, or above, 4 picocuries per liter (pCi/L). Being exposed to a level of 4 pCi/L has similar health effects as smoking 8 cigarettes per day.

The only way to know if your home has a high level of radon is to test for radon. Radon test kits are available from several sources, including local retailers, the Extension Office, and by ordering online at www.UGAradon.org. Purchasing a kit from the Extension office costs $10.

If the radon level in your home is high, it is fixable. Installing a radon reduction (or radon mitigation) system will reduce high levels of indoor radon to acceptable levels. The system most commonly used is a vent pipe system, which includes a fan that pulls radon from beneath the house and vents it to the outside.

Just because your neighbor has had a negative radon test does not mean that your house isn’t affected. Also, if your neighbor has had a positive test it doesn’t mean that you have radon in your home. It is advisable to test your own home. Experts usually advise that you have your home tested regularly to make sure that radon levels are low.

Radon may also be found in drinking water. This is primarily a concern for individuals whose drinking water comes from private wells. In Georgia, wells drilled into granitic crystalline rock aquifers (pretty common for wells around here), are at risk of naturally occurring radon contamination. This is where the uranium that decays to radon can be found at higher levels. If you don’t know if there is radon in your well water, have the water tested. The UGA Agricultural and Environmental Services Laboratories in Athens tests water samples for the presence of radon. To get a water testing kit, contact your local Extension Office. Testing for radon in water costs $40. For more information on radon, visit www.ugaradon.org. Radon can be a serious concern in our area. It’s best to be tested to know if you have dangerous levels in your home.

Towns County speech training program encourages student participation

HIAWASSEE, Ga. – The Towns County Speech Development and Showcase will begin a new year’s program on Thursday, Jan. 25, 2018, at 6:30 p.m. at the new Senior Center in Hiawassee. Sponsored in partnership with the Towns County Movers & Shakers and the University of Georgia (UGA) 4-H Extension, the training is geared to provide local students with an opportunity to improve their public speaking abilities, increase communication skills within group settings, and offer a chance for students to share their voices throughout the community.

“The Movers & Shakers speech contest provided me with the tools I need to be more confident and efficient in public speaking,” past participant C.J. Owens said. “The training I received has helped open doors for me in my education, as well as in the business realm.”

The goals of the program are designed to build student confidence levels in order to aid their interactions in classroom discussions, enhance the English, Language, Arts (ELA) Standards of Excellence, prepare for success in the workforce, and empower by helping the students to use their voices, rather than their actions, to solve problems.

“The Mountain Movers & Shakers speech competition has helped me more than I ever thought it could. Learning to speak in public has opened so many doors for me and has certainly helped to boost my confidence in social atmospheres,”  Emma Kate Ledford expressed.

The benefits of the speech training include necessary development for student body leadership positions, the ability for youth to create a “name” for themselves within the community, increased confidence levels in work or school interviews, and an opportunity to add program participation to college applications and employment resumes.

The training sessions will be held each Thursday from Jan. 25 until Feb. 22, 2018. The showcase will take place on March 1. All events are scheduled for 6:30 p.m. at the new Senior Center, 954 North Main Street in Hiawassee. Participation in the showcase itself is not mandatory but encouraged.
