Our wheat planting is beginning now and a little later than usual. We still have cotton in the field and late harvest is pushing back our wheat planting. Here is some wheat just now coming up and looking good. A few inches of rain a week ago and soil moisture is good.
As wheat emerges, we want to look out for ryegrass on field edges and black birds pulling up seedlings. If we plant beyond this point, we need choose an early maturing variety with low vernalization. We would also need to increase our seeding rate by 15 – 20 %.
Establishing a row traffic pattern for all post-emergence field traffic can be a good idea to reduce injury to wheat. You can set up a tramline by closing one or more openings in the drill when planting or spraying herbicide to kill the rows that match sprayer. Now is the time to consider traffic patterns if you choose to have them.
UGA Extension Grain Agronomist, Dr. Dewey Lee, has this to say about developing tramlines:
Using tramlines in intensively managed wheat makes applying uniform sprays of nutrients and pesticides much easier. They improve the precision of applications. They can be used as guides for repeated applications and save on the cost of aerial applications. They reduce the chance of disease development when compared to plants that are crushed by running over standing wheat. Studies have shown that the border plants will compensate for yield losses whereas plants damaged by tires rarely produce good grain.
Tramlines may also be formed after the crop has emerged by chemically killing the rows with glyphosate that match the width of the implement used to apply fertilizer or pesticides. Precision agriculture tools such as light bars and GPS guidance systems can help reduce the error of overlapping when spraying. Chemically kill wheat early once the plant has one to two developed leaves.
Fall is a good time to get our soil testing started. Now that harvest is nearing completion, you may want to make note of those trouble spots by sampling them separately. Sampling is even more important this year when taking into account all the rain we experienced that has probably leached some nutrients. It will be very important to make sure soil fertility is back up to a recommended level. Field pH could also be a concern with all of our rains this past year. Cody Weaver (left) has been working at Eddie Redding’s farm some time now and has learned so much, he is now teaching me. I make sure to visit Cody as much as I can to stay up to date on what’s going on in the field. We went out Friday and took some soil samples ourselves.
Below is information put together by Irwin County Agent, Phillip Edwards on UGA Soil Test Lab Supporting Grid Sampling:
Growers can use the technology of grid soils sampling and precision fertilizer application. Our UGA Soil Test Lab can provide grid sampling results in a common format compatible with many of the precision Ag solftware packages. There has been a big jump in the use grid sampling and then using those sampling results for variable rate fertilizer applications. I had a chance to talk to our UGA Soil Lab and they have a number of clients who have been submitting soils samples to our lab in a form that is compatible with those programs. The first 100 samples are $6 each and thereafter they go to $5. Our office has soil test bags or the lab can send you soil boxes and bags for your use.
Below is information on changing from diesel irrigation engines to electric motors from Mr. Calvin Perry at UGA Stripling Irrigation Research Park:
The Georgia Environmental Finance Authority (GEFA)… announced a second round of the Georgia Agricultural Irrigation Motor (AIM) Program, an incentive program designed to help Georgia farmers become more energy-efficient, save money on fuel costs, and reduce emissions… The Georgia AIM Program will provide farmers with a rebate to replace inefficient diesel irrigation engines with energy-efficient electric irrigation motors. The rebates will cover 25 percent of eligible project costs, with a $10,000 maximum rebate available.
Go to this website for more details: http://www.gefa.org/Index.aspx?page=50&recordid=591&returnURL=%2findex.aspx
The application period for the program opens online at www.gefa.org on Wednesday, December 4, 2013, at 8:00 a.m. Available funding is limited and rebates will be awarded on a first-come, first-served basis. The application period will close Saturday, February 15, 2014, at 5:00 p.m.
We are still finishing up with cotton harvest, and quite a few fields are yet to be picked. Some rain has slowed down the past few days. There are some good yield reports coming in considering our wet season. We still have some time to go.
The Georgia 2013 Corn Performance Tests and the preliminary 2013 Cotton OVT data for Tifton, Plains, and Bainbridge is now available on the State Variety Testing web site at www.swvt.uga.edu.
Last night we did not quite reach freezing in air temperature, but still had our first frost. Here is a graph below of the Dixie weather station at www.georgiaweather.net.
According to UGA Extension Cotton Agronomist, Dr. Guy Collins, even one night of 32 degrees can close bolls and shut down development. However, the real key is frost. Because of growth environment, each field is affected differently. A real light frost on a mature boll is not bad. But, if you have an immature boll with higher water content, it is more susceptible to frost. We will start to see rotted bolls and even be able to smell them. Photo above is freeze damage from last night.
Unless a field escaped frost, it is not worth waiting on now. When we have daytime temperatures around 70 and night time temperatures around 50, we are not accumulating any heat units.
We’ve had a significant amount of cotton picked this week, even though harvest is late. Not only did we have lots of rainfall this season, but lots of cloudy days. This combined with cooler fall weather could has slowed its development the past couple of weeks. Most of our fields are defoliated but we still have a good amount of cotton to pick. Growers who planted between late-May and mid-June were more delayed for harvest due to late summer rains and a falls cold spells.
November 14, 2013 TIFTON, Ga. – The Georgia Peanut Commission, in cooperation with the National Peanut buying Points Association and peanut food manufacturers, will host the 2013 Farmer Appreciation Day at the GPC office located in Tifton, Ga., from 9 a.m. to 3 p.m. on Monday, Nov. 25, 2013. Georgia’s peanut farmers, along with other farmers throughout the state, are invited and encouraged to attend. Many statewide dignitaries and media representatives have been extended an invitation, as well, and are welcome to join GPC and peanut growers in
celebrating the hard work of Georgia’s farmers.
To kick off the celebration, a brief program will begin promptly at 11 a.m. Country-fried peanuts, boiled peanuts, grilled peanut butter and jelly sandwiches and other refreshments will be on-site and available throughout the
day. Georgia Peanut Commission Chairman, Armond Morris thinks the Farmer Appreciation Day could not have come at a more perfect time of year to show gratitude for Georgia’s farmers. “It’s harvest time in Georgia, and what a better time to celebrate and honor the men and women who feed and clothe us than the week of Thanksgiving,” Morris said.
Attendees will be given the opportunity to meet with the GPC board of directors and staff, as well as tour the state-of-the-art Georgia Peanut Commission office. Anyone interested in attending the Farmer Appreciation Day is welcome
to attend; an RSVP is not necessary.
The Georgia Peanut Commission represents 3,500 peanut farmers in the state of Georgia and carries out programs in the areas of research, promotion and education. For additional information on the programs of the Georgia Peanut
Commission, visit www.gapeanuts.com.
Preplant fertilizer will depend mostly on what was just harvested from the field this season. UGA Extension Grain Agronomist, Dr. Dewey Lee, says pH is best between 6 – 6.5. We will see manganese deficiency at a pH of 7. The amount of N we need depends on previous crop. Below are recommended N amounts:
- Cotton – 40 lbs/ac
- Corn of Fallow – 30 lbs/ac
- Soybeans – 20 lbs/ac
- Peanuts – 10 lbs/ac
Tillers produced in the fall generally produce the most grain per unit area. It is important not to over-fertilize with N in the fall as it may cause excessive growth and result in winter injury.
Total N will be between 100 and 130 lbs per acre. We need most of it in January and February as one or two sidedressings – depending on tillering.
Timing of N fertilization should be based on the pattern of uptake by the crop. Demand for N is relatively low in the fall but increases rapidly in the spring just prior to stem elongation. Therefore, make the fall applications of nitrogen at planting, and the remaining N prior to stem elongation (Zadoks 30). Use the lower rate of fall applied nitrogen at planting on heavier-textured soils and the higher rate on sandy soils.
Other nutrients should be applied according to a soil test preplant.
Since 65% of the total P uptake and 90% of the total K uptake occurs before the boot stage, these nutrients should be applied according to soil test before planting and thoroughly incorporated into the rooting zone. It is unnecessary to split potash applications.
