Conversations this week have centered on the forecast lows over the coming weekend, boll maturation at temperatures averaging below 60F, and slow activity of defoliants and boll openers. In this blog, I briefly tackle each of these issues. Continue reading

Defoliation thoughts as we move into October
This has been a big week for defoliation. Most of the calls have consisted of one or two questions. First, how long should I wait on acres that are nowhere near ready and second, what is the concoction when the weather is this cool? In this blog, I share a few thoughts on timing and some results from a strip trial we completed in cool conditions during 2020.
Pond Aeration Field Day in Covington Oct 18th
On October 18th at 10:00 am there will be a pond meeting on aeration. Fisheries Biologist Bob Robinson from Kasco aerators will be discussing everything about aerators. He will even have a couple of types there to see. The meeting will be at:
468 Charlie Owen Rd in Covington TN.
There is a covered pavilion with picnic tables and chairs as well as a restroom. Memphis Net and Twine and Kasco are sponsoring our lunch so I will need a head count. Please call the office at 901-476-0231 or email me at email@example.com or Jeff Via at 901-476-0231 or firstname.lastname@example.org if you plan to attend.

Impact of Drought on Residual Soil Nitrate
Abnormally dry soil conditions as a result of rainfall amounts far below average during this corn growing season present unique nutrient management decisions after harvest, particularly for growers considering wheat crop this fall. This article will address two key questions that may come handy in making management decisions: Is there be considerable amounts of residual soil N left after the 2022 corn crop? and if the residual soil nitrate is sufficient to meet N demand of the wheat crop in the fall?

Physiological vs seasonal cutout: Estimating the last effective bloom
It is hard to believe how different this crop looks now compared to the end of July. Although our earliest planted acres and acres planted on ‘thin’ ground have mostly bloomed out of the top, many of our later planted acres and acres on moderate to strong ground have just passed peak bloom. In 2022, the last effective bloom on many of our earliest planted, cutout acres flowered weeks ago. In contrast, the last effective bloom of our later planted acres will likely be determined by the number of heat units remaining in the season. You can easily see these two contrasting scenarios in the above video; the later planted cotton has blooms throughout the canopy and is riding 4-6 NAWF while the earlier planted cotton cutout weeks ago. In this blog, I tackle the concept of last effective bloom, our predicted last effective bloom date and how we must use these concepts in 2022 to maximize our return on investment. Continue reading
