Fall is a great

time to sample soil

If you think spring is the best time to take soil samples, you might want to rethink that. Fall is actually the optimum time to take soil samples for fertility analyses.

Fall sampling gives you plenty of time to follow fertility recommendations before planting season. As soon as you receive the soil test results, look at the recommendations for lime and pH, a measure of soil acidity that affects plants’ uptake of all nutrients. If the soil pH is too low, it decreases the uptake of essential nutrients, and elements like aluminum and manganese can become toxic to growing plant roots.

Applying limestone neutralizes soil acidity. Because agricultural lime takes about six months to break down and react with the soil, it should be applied in the fall to be fully effective in the spring. Unlike fertilizer, lime is needed every three to five years, depending on your crop rotation and nitrogen fertilizer history. The only way to determine if your fields will need lime next year is by soil testing this fall.

The turn-around time for test results is much faster in the fall, usually within a week of submission, because fewer people are submitting samples.

You can also apply all the recommended fertilizers, except nitrogen, in the fall. Often a fall application will save you considerable money, because fertilizer prices generally are cheaper in the fall as a result of lower demand. In addition to lower fertilizer prices, it’s easier to get the spreader truck in the field during the fall, because the soil usually is drier.

If you don’t soil test, you can only guess at the fertility needs of your fields, and far too often those assumptions are wrong. Guessing at the amount of fertilizer to apply often results in applying more than the recommended rate. Some producers want to be sure there’s plenty of fertilizer available in case they have a bumper crop next season. However, studies have shown that crops need the same amount of fertilizer in a good year as in a poor year.

If you’re interested in collecting fall soil samples, stop by the Clinton County Extension Office. We can give you details on how to take accurate soil samples and also have soil probes to loan for taking samples. The Clinton County Soil Conservation District will provide up to three samples per producer at no charge, normal fee is $7 per sample.

Remember, spending some effort on soil sampling this fall can keep you from wasting time and money. Fall soil samples also can provide big returns for next year’s crop.

Beekeepers meeting

October 11

The Clinton and Cumberland County Extension Offices will be hosting a beekeeper meeting on Tuesday, October 11, at 6:00 pm CT at Albany RECC with Greg Whitis speaking. Greg is a beekeeper himself and also County Extension Agent for Agriculture and Natural Resources in McCreary County.

The next meeting in the series will be on November 10, at 6:00 pm CT at the Cumberland County Extension Office with Dr. Tammy Horn Potter, KY State Apiarist speaking. Some topics include, basic beekeeping, pollinator habitat, honey quality and marketing, sources for purchasing bee supplies, etc.

If you are already a beekeeper or thinking about getting into beekeeping, you should make plans to attend these informative sessions on honeybees.

Refreshments will be served at each session. Call the Clinton County Office at (606) 387-5404 or the Cumberland County Office at (270) 433-7700 to reserve your spot today.
