The 3LB's Molasses Manual - a growers guide to soil sweeteners

[H2L]

There are a number of different nutrient and fertilizer companies selling a variety of additives billed as carbohydrate booster products for plants. Usually retailing for tens of dollars per gallon if not tens of dollars per liter, these products usually claim to work as a carbohydrate source for plants. A variety of benefits are supposed to be unlocked by the use of these products, including the relief of plant stresses and increases in the rate of nutrient uptake. On the surface it sounds real good, and while these kinds of products almost always base their claims in enough science to sound good, reality doesn't always live up to the hype.

The 3LB are pretty well known for our distrust of nutrient companies like Advanced Nutrients who produce large lines of products (usually with large accompanying price tags) claiming to be a series of “magic bullets"

Molasses is a syrupy, thick juice created by the processing of either sugar beets or the sugar cane plant. Depending on the definition used, Sweet Sorghum also qualifies as a molasses, although technically it's a thickened syrup more akin to Maple Syrup than to molasses. The grade and type of molasses depends on the maturity of the sugar cane or beet and the method of extraction. The different molasses' have names like: first molasses, second molasses, unsulphured molasses, sulphured molasses, and blackstrap molasses. For gardeners the sweet syrup can work as a carbohydrate source to feed and stimulate microorganisms. And, because molasses (average NPK 1-0-5) contains potash, sulfur, and many trace minerals, it can serve as a nutritious soil amendment. Molasses is also an excellent chelating agent.

Several grades and types of molasses are produced by sugar cane processing. First the plants are harvested and stripped of their leaves, and then the sugar cane is usually crushed or mashed to extract it's sugary juice. Sugar manufacturing begins by boiling cane juice until it reaches the proper consistency, it is then processed to extract sugar. This first boiling and processing produces what is called first molasses, this has the highest sugar content of the molasses because relatively little sugar has been extracted from the juice. Green (unripe) sugar cane that has been treated with sulphur fumes during sugar extraction produces sulphured molasses. The juice of sun-ripened cane which has been clarified and concentrated produces unsulphured molasses. Another boiling and sugar extraction produces second molasses which has a slight bitter tinge to its taste.

Further rounds of processing and boiling yield dark colored blackstrap molasses, which is the most nutritionally valuable of the various types of molasses. It is commonly used as a sweetner in the manufacture of cattle and other animal feeds, and is even sold as a human health supplement. Any kind of molasses will work to provide benefit for soil and growing plants, but blackstrap molasses is the best choice because it contains the greatest concentration of sulfur, iron and micronutrients from the original cane material. Dry molasses is something different still. It's not exactly just dried molasses either, it's molasses sprayed on grain residue which acts as a

The How's of Molasses

Undoubtedly some folks are to the point where they are ready for our flock to “cut to the chase." All the background about molasses making and the various kinds of molasses is good, and knowing how molasses works as a fertilizer is great too, but by now many of you may be thinking - isn't it about time to learn how to actually use this wonder product?! So this section of the “Molasses Manual" is for our birdie buds who are ready, waiting, and wanting to get going with bringing the sticky goodness of molasses into their garden.

Molasses is a fairly versatile product, it can serve as a plant food as well as a an additive to improve a fertilizer mix or tea. Dry molasses can be used as an ingredient in a fertilizer mix, and liquid molasses can be used alone or as a component in both sprays and soil drenches. Your personal preferences and growing style will help to decide how to best use this natural sweetener for it's greatest effect in your garden.

We will try and address the use of dry molasses first, although we will openly admit this is an area where we have little actual experience with gardening use. We've certainly mixed dry molasses into animal feed before, so we're not totally unfamiliar with it's use. Folks may remember from our earlier description of the various kinds of molasses that dry molasses is actually a ground grain waste “carrier"

That looks at most of the beneficial uses of Molasses for the modern organic or biological farmer. Just when you think that's all there could be from our beaks on the topic of molasses, that molasses and it's sweet sticky goodness surely have been covered in their entirety, the birds chirp in to say, there is one more specialized use for molasses in the garden. Magical molasses can also help in the control of Fire Ants, and perhaps some other garden pests.

Molasses For Organic Pest Control

One final benefit of molasses is it's ability to be used in the control of a couple of common pests encountered in gardening. The most commonly known use of molasses is it's ability to help control Fire Ants, but we've also found an internet reference to the ability of molasses to control white cabbage moths in the UK, so molasses could be an effective pest deterrent in more ways that we are aware.

As we said before, there are several references we've run across refering to the ability of molasses to control Fire Ants. Since we're not intimately familiar with this particular use of molasses, and rather than simply re-write and re-word another's work, we thought we'd defer to the experts. So for this section of the current version of the Molasses Manual, we will simply post a reference article we found that covers topic in better detail than we currently can ourselves.

[QUOTE]Molasses Makes Fire Ants Move Out
By Pat Ploegsma, reprinted from Native Plant Society of Texas News
Summer 1999

Have you ever started planting in your raised beds and found fire ant highrises? Are you tired of being covered with welts after gardening? Put down that blowtorch and check out these excellent organic and non-toxic solutions.

Malcolm Beck 1, organic farmer extraordinaire and owner of Garden-Ville Inc., did some experiments that showed that molasses is a good addition to organic fertilizer (more on fertilizer in the next issue). When using molasses in the fertilizer spray for his fruit trees he noticed that the fire ants moved out from under the trees. “I got an opportunity to see if molasses really moved fire ants. In my vineyard, I had a 500 foot row of root stock vines cut back to a stump that needed grafting. The fire ants had made themselves at home along that row. The mounds averaged three feet apart. There was no way a person could work there without being eaten alive! I dissolved 4 tablespoons of molasses in each gallon of water and sprayed along the drip pipe. By the next day the fire ants had moved four feet in each direction. We were able to graft the vines without a single ant bothering us."

Last Bird's Eye Look At Molasses

You've heard a lot now about the sweet sticky goodness of Molasses in the garden, but have we mentioned yet that some folks even view Molasses as a health food?

One of the 3LB's had a grandmother who would take a swig of molasses twice every day as a part of her health regimen. We don't add that as a random fact, but mention it because there's an interesting little story attached . . .

Grandma was driving down the road one day, oblivious to her surroundings, when she was struck with the remembrance that her morning molasses had been forgotten. Most folks wouldn't have had a solution for this problem at hand, but we have to tell you that this is a lady who traveled with a small bottle of molasses in her purse!

So Grandma grabbed the brown bottle of molasses from her purse, and proceeded to uncap it and take a gulp as she drove somewhat uncertainly down the road. Chance would have it, that as she performed this somewhat delicate action, she was observed by an officer of the law weaving down the road. Officer LEO observed Grammy directly as she lifted the small brown bottle to her lips. Of course in that day, beer didn't come in an aluminum can, but instead was distributed in little brow bottles that looked quite similar to the molasses bottle Grandma had just swigged. We don't need to tell you where the law enforcement officer's mind went.

Putting two and two together to equal an apparent and immediate danger to the community in an act of wanton disregard for the law, Officer LEO flipped his vehicle around in a 180 turn, flipped on his lights, and began to pursue Grandma. This was a lady we never were quite comfortable letting children ride with, but it was also a day and age before there were many laws allowing intervention to remove the license of an elderly person no longer competent to drive.

So, we will just say it was a little while before Grandma noticed the red flashing lights in her rear view mirror. After all she'd been busy putting her molasses away in her purse and watching the road ahead of her, not looking back behind. It probably didn't help that Grandmother's first instinct was also to believe that the flashing lights behind her were really meant for someone else.

It certainly didn't occur to Grandma that all of her actions worked to confirm in Officer LEO's mind that he was dealing with an intoxicated old crone with an apparent total disregard for the not only the law, but also other's safety. And we probably don't need to tell you that he wasn't feeling particularly kind or generous when Grammy finally did pull to the road's shoulder. As the officer finally approached her car, prepared for trouble from some kind of inebriated old crone, Grandmother came hobbling from her own vehicle a bit unsteadily due to her advanced arthritis.

Fortunately we can report that the final ending was happy, without too much unnecessary drama. After verbally demanding the officer's intent, and then producing the offending brown bottle for the officer's inspection, grammy was supposedly heard to say,

One thing to add..when using molasses in an organic microbe friendly environment always use Unsulfured Molasses.

Sulfur is a very potent fungicide, that is why it is added to molasses...so that a farmer can have a 55 gallon drum of molasses sitting out in the heat and sun in the feedlot and it doesn't go bad.
