As summertime temperatures heat up, cool season farm and ranch pastures begin to lose productivity.

This can cause us to think about other ways to stretch or improve our ability to feed livestock. One possibility is alternative (cover) crops for livestock feeds. These crop mixes often include legumes, grasses and brassicas (turnips or radishes). Planted in the fall, these mixes can provide extra feed to help conserve or extend limited feed resources.

To learn more about these alternative crop mixes, join the K-State Research and Extension –Southwind District on Thursday, July 13, at 6 p.m. This meeting, which includes a meal, is sponsored by Landmark National Bank and will feature K-State Research and Extension Southeast Area Livestock Specialist Jaymelynn Farney. Dr. Farney will discuss research data relating to actual cover crop trials. The program will take place at the 4-H Building in Fort Scott, Kansas and a $10.00 fee, payable at the door, will cover the cost of meals and materials. Please pre-register by calling the Southwind District –Fort Scott Office at 620-223- 3720.

With summer temperatures on the rise, now is the time to look for alternatives to save a few dollars while trying to cool the home. K-State Research and Extension offers the following advice:

Can ceiling fans effectively reduce air-conditioning costs?
Any type of fan can be effective in reducing air-conditioning costs if the air movement helps occupants feel comfortable and results in increasing the thermostat temperature setting. If the air conditioning thermostat setting is not increased, there are no savings. The cooling effect of moving air can compensate for as much as a four-degree rise in temperature. Keep in mind, that during the heating season, the air movement caused by the fan will still have the same cooling effect.
How can I keep my home cooler in the summer without air conditioning?
The simplest, least expensive method to keep a home cool is shading walls, windows, and the roof. Interior shades are inexpensive and easy to install. Use pull-down or Venetian blinds in addition to regular window coverings. Window coverings should be light colored (white or beige). There are several ways to keep a home cool without overusing the air conditioner. Of these options, install shades first. Compare utility bills before and after the installation of shades. If satisfied with the savings, stop there, but if savings are not significant, look into other options. One option to consider is exterior awnings. They are more expensive than interior shades, but would be a great way to shade south windows. Natural shading is another way to block heat gain in summer. For example, plant broad-leafed trees on the south and west sides of the home. They shade a home in summer months and will let in sunlight during winter months when they have shed their leaves. Certain steps will help keep a home warm in winter and will help cool it during the summer. Insulated walls and roof reduce heat gain, just as they lower heat loss in winter. As a general rule, ceiling insulation should have an R-value of 35 to 45, and walls from 19 to 27. A light-colored roof also decreases heat gain. Use the above suggestions, coupled with circulating fans inside the home, and utility bills will be less than if air conditioning was the only cooling source.
Is it better to leave the fan running continuously with the air conditioner or to place it in the automatic position?
It is more efficient to leave the thermostat in the automatic position. The fan consumes only one-tenth the energy of the compressor, but when it runs continuously, the fan can cost up to $30 a month. This amount can be reduced by cycling the fan only when it’s needed. Additionally, the air conditioner will dehumidify the air only when the compressor is running. However, if the fan remains on after the compressor cycles off, some moisture on the coil will re-evaporate. This moisture must be removed during the next compressor cycle, which increases the energy consumption.
If air distribution is poor within the home or business and hot spots or very cold areas result, the fan can be run to even out the temperatures.  However, the fan should be set to the auto position when the building is unoccupied. Even better, shut the air conditioner off or raise the thermostat setting when leaving the building.
Will I save energy by turning off my air conditioner when I leave home, or am I better off just letting it run?
If gone for four hours or more, more energy will be saved by turning off the air conditioner or turning up the thermostat. During the day, keep windows shut and close curtains or blinds on any windows that will be exposed to sunlight. The thermal mass of the house will probably keep the indoor temperature well below the outdoor temperature, and the house should cool quickly when the air conditioner is restarted. Use a programmable thermostat or timer to turn on the air conditioner 30 to 45 minutes before the expected arrival home. If the home is still warm upon arrival, turn on a fan to create air movement.  Moving air can make the air feel about four degrees cooler than it really is.

Just like last year, we have been gotten a lot of rain this spring. Our soils were definitely saturated for several weeks. You may think that watering won’t be needed for quite some time since soil moisture levels are very high. However, watering may be needed much sooner than you think.

Excessive rain can drive oxygen out of the soil and literally drown roots. Therefore, as we enter hotter, drier weather, the plants with damaged root systems may be very susceptible to lack of water. Don’t forget to check your plants for signs of wilting or leaf scorching and water as needed.

My annual flowers haven’t been overly impressive yet. I know as our temperatures warm, they will pick up blooming speed. To keep the blooms going, a nitrogen fertilizer application and removing spent flowers is a must. An application of fertilizer is especially needed this year considering the amount of rain we have gotten recently.

Modern annual flowers have been bred to flower early and over a long period of time. Providing nitrogen through the growing season (sidedressing) can help maintain flower display. A high nitrogen sidedressing should be applied four to six weeks after flowers have been set out. Additional fertilizers every four to six weeks are also helpful during a rainy summer or if flower beds are irrigated. Common sources of nitrogen-only fertilizers include nitrate of soda, urea and ammonium sulfate. Use only one of the listed fertilizers and apply at the rate given:

 Nitrate of soda (16-0- 0) – Apply ¾ pound fertilizer per 100 square feet

 Urea (46-0- 0) – Apply ¼ pound fertilizer per 100 square feet

 Ammonium sulfate (21-0- 0) – Apply ½ pound fertilizer per 100 square feet

If you cannot find the above materials, you can use a lawn fertilizer that is about 30 percent nitrogen (nitrogen is the first number in the set of three) and apply it at the rate of 1/3 pound per 100 square feet. Do not use a fertilizer that contains a weed killer or a weed preventer.

Removing spent flowers or “deadheading” will help some plants bloom more profusely. Annuals focus their energy on seed production to insure that the species survives. If old flowers are removed, the energy normally used to produce seed is now available to produce more flowers. Deadheading is as easy as pinching the plant between the thumb and finger, but tough, wiry stems will require the use of scissors or pruning shears.

Plants that do increase blooms in response to deadheading include: hardy geraniums, coreopsis, some petunias, marigolds, snapdragons, begonias, some roses, zinnias, sweet peas, salvia, blanket flower and yarrow.

There are some “self-cleaning” plants on the market now. These plants drop their spent flowers and bloom again and do not require manual deadheading. In many cases they are sterile varieties – bred not to produce seeds. The petunia and rose varieties that are “self-cleaning” continue to excel in the home garden market because of their low maintenance and blooming power.

If you need help with any horticulture topic, give me a call. My current office schedule is Monday, Wednesday, Friday – Erie; Tuesday – Iola; and Thursday – Fort Scott.
