Cotton for the past hundred years or so has been King in West Texas agriculture, and until the end of WWII, cotton production involved more persons and families than any other industry. But after the war modern farm machinery displaced many farm families, and job opportunities in cities lured many more off the farm, so the result was larger farms, fewer farmers and a general decline in rural West Texas communities. Lost in this off-the-farm migration was a general knowledge of cotton culture that farm families had passed down through several generations ... that was forgotten when the last two or three generations moved to town. Chances are most of you are descendants of cotton farmers, two or three times removed. The following notes are offered as a refresher to enable you to converse with Uncle Jed when you visit him on his dryland cotton farm.
The word Cotton comes from an Arabic word al qutun, as did the Spanish word algodon for cotton fiber (and you thought algodon on the label of a shirt recently meant some synthetic fiber.)
The cotton specie grown in the US is Gossypium hirsutum. The term Gossypium pertains to the characteristic of certain plants to contain gossypol in their fruit. Gossypol is a substance in cotton seed that is a natural defense of the plant to some insects ... and is toxic to some animals. Cattle with chambered stomachs can digest whole cotton seed in limited amounts (about 5 lbs/day.) Processed cottonseed products that have gossypol removed can be safely fed in larger amounts.
Surprise. The plant that is first cousin to Cotton is Okra. It also contains gossypol. (Now you have an excuse for not eating boiled okra ... but a lame one because boiling or frying neutralizes gossypol ... beside that, you probably could not consume a lethal dose.) If you are observant you will recall that the cotton blossom and the okra bloom are virtually identical and both last three days before falling off. Also, the green cotton boll and the okra pod are similar in construction.
A Fine West Texas Cotton Patch
Question for the day ... were West Texans ever cotton pickers? Answer: probably not. In the old days cotton picking was the term for deftly plucking the locks of cotton from the burr and placing it in the cotton sack. The method in West Texas was to slide the fingers under the burr and pull the burr with the cotton locks and place all into the sack. This was called "boll pulling." The reason was West Texas, because of the wind, requires a type of cotton where the locks adhere more tightly to the burr than in say Louisiana where they pick cotton. This same principle applies to mechanical means of harvesting ... West Texans primarily uses strippers that strips locks, burrs, leaves, etc., from the plant. In Louisiana they use cotton pickers with a bunch of spinning spindels that pluck the cotton locks.
You all have seen trucks loaded with cotton bales on the way to Galveston. How much does a bale weigh and how much picked/pulled cotton is required to make a gin bale. A bale of lint cotton weighs approximately 500 pounds. To get a bale of cotton by stripper requires approximately 2,000 pounds ... this will yield about 500 pounds of lint cotton, 500 pounds of cotton seed, and 1,000 pounds of burrs and other trash. (The ginning process removes the burrs and trash, and separates the seed from the lint.) Clean picked cotton required about 1,000 pounds of cotton to gin out a 500 pound bale of lint and 500 pounds of seed.
How does the plant arrive at an open boll of lint cotton? Easy. Like any other flowering plant at some point in maturity it will produce flower buds. These buds on cotton are called "squares." The squares eventually open and produce the blossom. The cotton blossom falls off in three days, leaving a small boll about the size of the end of your pinkie. A funny thing about that little boll is that it has all of its fibers inside already and every fiber is as long as it will ever get. What happens as the boll matures is that the fibers get larger and stronger. These cotton fibers are almost pure cellulose. Now think of a single fiber ... it is shaped like a soda straw and inside will be 20-30 layers of cellulose coiled in a neat spiral of natural springs (shaped like 20-30 helixes.) This is the feature that gives the cotton fiber a high degree of strength, durability and absorbancy. Growing conditions determine the number of helixes that will be present in an individual fiber ... and this is what is measured by the test of "micronaire" (a test of the tensile strength of the fiber in cotton grading ... the term used is the "mike." Another test used is fiber length (called staple) ... this is determined by genetics which in West Texas is about 7/8 to 15/16 inch and is considered short staple. The staple length and micronaire measurement are what determine the spinning quality of the fibers. (Pima cotton and Egyptian cotton are long fine staple cotton and are a different variety from hirsutum.)
Every bale of cotton upon coming out of the press at the cotton gin has a big wad of lint cut out and labeled for eventual grading by government experts at that art. The grade eventually determines the market price for that particular bale. In grading, in addition to the staple length and "mike" measurement, the lint is graded for color and trash content. Lint stained from blown red dirt, rain while in the field, and green leaves in stripping all lower the grade as does trash not cleaned out during ginning. This is the reason West Texas cotton is always at the bottom of these grades because of the stripping process and blowing sand. (Because additional processing is required to clean it ... otherwise it ends up as cotton ducking or tarpaulins instead of ladies' blouses.)
Cotton lint is hand graded by persons with extensive training. In earlier times there were about 60 possible grades but this was reduced to about 30 25-30 years ago. In recent years attempts have been made to mechanize this with high tech scanners etc., but none have come close to the accuracy of the trained human eyes. So grading is still done by hand and eyes.
Cottonseed is an interesting product. The seed is separated from the lint during ginning. Now the seed is not attached directly to the cotton fibers within the boll and ginning separates it easily ... but the seed has tiny fibers of its own on its coating. The fibers are about 1/8 inch long and are called "linters." Linters are shaved off the seed in the first processing step at a cotton oil mill. These linters are bundled and sold to make your fine cotton paper. Then the cotton seeds are crushed to produce cottonseed oil which is used like any other vegetable oil. The cottonseed hulls are poor quality cattle feed but the innards are used in cottonseed meal, cake, bran and other high-protein cattle feed.
Now the hazards of being a cotton farmer ... weather and insects (fluctuating prices are just the everyday gamble of any farm product.)
Cotton requires a good moisture seasoning in order to germinate and get that early growth. In the older times farmers waited with tractors or mules at the ready for that first April or May rain to start planting. If the rain did not come by mid-May they were in a world of hurt because of the length of the growing season put them near the first fall frost date. Nowadays, statewide regulation determine the first planting date because of the Boll Weevil eradication program ... so now timewise, West Texas farmers are operating on the very edge.
The best growing conditions for cotton are hot days and cool nights. If the crop was started with a good planting seasoning, the plant has a tap root that will seek out moisture if any is down there so it is hardy in dry weather ... but some rain in June or July is necessary to make a decent crop. But once the bolls are formed, no more rain is wanted. Rains after the bolls are set do not help the fruiting ... and instead causes the plant to produce more leaves. An extra helping of late leaves just means more staining and trash which will drive the grade down ... and a lower price.
Now for insects. There are a lot of them but the Big-3 are Leaf Worms, Boll Worms and Boll Weevil ... nasty little creatures. Leaf worms can be handled pretty well by farmers now with better insecticides and spray equipment. But before the 60s they were terrors. They attacked the growing plants during a cool or rainy spell ... and honestly, overnight you could go back to the field the next day and virtually every leaf in the field would look like lace ... what was green the day before would be white. That brought about a frantic search at feedstores, cotton gins, coops, etc., for Paris Green or any Arsenic compound dust to do battle. In a days time a crop could be lost (for sure over a weekend.) I remember those days when the entire family would be out doing whatever necessary to get the poison dust applied ... and the neighbors would be doing the same. Then you waited several days to see if you had been successful ... if green reappeared.
Boll worms and boll weevils were more insidious. You had to be continually checking individual plants for signs of infestations. Weevils would sting the forming boll at early stages and deposit an egg. The first sign would be squares on the ground where they had fallen off the plant. Pop them open and find a weevil grub. Same applied for boll worms. The stages could go from no signs to total infestation in just a day or so. The problem was once the worm or weevil were inside the boll it was too late ... at first sign you had to invest in spray or dust or risk losing a crop in short order.
There was a country-western singer back in the 50s known as Tex Ritter (you may be more familiar with his son John Ritter) from Panola County, Texas. Tex had a song about the Boll Weevil that went ... "the weevil got half the cotton, the merchant got the rest, and all he left the farmer's wife was one old cotton dress"... I reminded my mother of that old song at her 90th birthday party and she laughed ... and then she cried ... she remembered those times when we battled the worst nature had to throw at us.
Cotton farmers in the early days were a tough breed. Every year and every day was a gamble ... and in the Fall they accepted their winnings or their losses with equal grace and prepared for the next year. Just know that your old great granddad and all his cotton farming family and friends are now resting comfortably in Heaven ... the Lord knows they had their Hell on earth.
