Some six months after planting the seeds of another
cotton crop, growers are finally ready to reap the benefits of their hard work.
Yes, it’s harvest time.
The
plants are a dry, golden brown after defoliation and the cut-off of irrigation.
You can see a sea of puffy white fiber across the fields.
“We’re harvesting,” declared field scout Damien
Jelen. “Harvesters are working all day.”

Growers monitor cotton moisture before picking the crop. |
Crews are working the fields for 12 hours, often
starting around 10 a.m. after the fiber dries off from the morning dew.
Usually, the harvesters – with their twirling spindles twist the fresh cotton
from the burrs attached to the dried plant stems – end the day around 10 p.m. or
when cool nighttime temperatures start increasing the fiber’s moisture content.
While
farmers are early risers, they often won’t start at the crack of dawn. It is
important for them to manage the moisture content of cotton so that they can
maximize yield and protect the fiber quality.
If the cotton is too wet, the fiber can stick to the
machinery and cause jams that can damage cotton balers and gin equipment. Also,
harvesters can pick up more trash and leaves along with the fiber.
Moreover, wet
cotton packed into modules can create another problem: “It can catch fire,”
Damien says through spontaneous combustion.
On the flip side, overly dry cotton can become
damaged during harvest and even ruin the fiber quality..

Experts say growers should check
moisture content frequently at the beginning and the end of the day. They can hand
test or use a meter. Here are some tips:
- Harvest when there is no dew present and the humidity in the air
is less than 70 percent. A good rule of thumb is if there is dew on vehicles
during harvest then the cotton is probably too wet.
- Bite into a cotton seed. It should be hard and crack in your
teeth.
- Feel the cotton to determine if it’s too wet. The ideal reading
on a moisture meter should be around 6 to 8.5 percent, according to the USDA. The
reading shouldn’t be more than 12 percent.
- Moist cotton will jam up in a harvester, causing the fiber to be
thrown in front of the picking heads.
- Check if dense globs of fiber are thrown
into the collection basket.

Alfalfa growers looking for one more harvest this season. |
While
the cotton harvest is gearing up, the alfalfa crop is winding down its harvest
season. Damien says a little rain during the first three days of the month was
enough water to trigger a growth spurt in alfalfa.
“Growers are going for one more cutting,” Damien
says. Usually, growers in the Valley will harvest six to eight times during the
season. They cut when the alfalfa is at least a couple feet tall.
Damien says this final cutting will take place when
alfalfa reaches around 18 inches tall. “It will be small bales.”
COTTON
FARM TOUR: There is still time to sign up for a behind-the-scenes look
at cotton production. The day-long tour is set for Thursday, October 25. Leading experts and professionals will offer
insights about cotton cultivation and processing, addressing issues such as
water use, cotton farming practices and the state of the market for Cleaner
Cotton™ fiber. Cost is $40 a person and covers bus transportation, a catered
lunch at the Cardella Winery in Mendota and snacks and water. The tour starts
at 8:15 a.m. at the Best Western Apricot Inn, 46290 West Panoche Road,
Firebaugh. Register through the Sustainable Cotton Project’s Eventbrite site.
