Researchers use gut bacteria to turn type A or B blood into universal donors.Bacteria found in the human gut could save countless lives by transforming type A or type B blood into type O. At a meeting of the American Chemical Society , Steve Withers of the University of British Colombia presented new research suggesting enzymes found in gut bacteria could effectively strip antigens from the two most common blood types. If successful, the discovery would essentially make most types of blood accessible to those who need it, regardless of their blood type.

AGRIBUSINESS: How to make homemade weedkiller with vinegar.

AGRIBUSINESS: How to make homemade weedkiller with vinegar. How to make homemade weedkiller with vinegar. The easiest recipe for vinegar weed killer is simply to use vinegar at full strength, without adding anything else. White vinegar is most often used for this purpose, although any vinegar will work.

This is because it increases the acidity levels. Adding anywhere from one tablespoon to one cup per gallon is a common recipe. 5)Vinegar and Essential Oil - Mix full strength vinegar with one tablespoon of essential oil of clove or orange. Some gardeners say the oil helps the mixture stick to the plants better to increase effectiveness. Vinegar as weedkiller

Roundup Made With Vinegar (Rather Than Glyphosate) Is Now Available .

Roundup Made With Vinegar (Rather Than Glyphosate) Is Now Available . Roundup is a pesticide (a weed-killer or herbicide) containing the active ingredient glyphosate. It is a controversial herbicide that is the most heavily used pesticide in the world. And since the introduction of Roundup Ready crops that have been genetically modified to survive repeated Roundup applications, the use is only increasing on farms. Several posts here, here, and here have discussed research and controversies with Roundup, and the numerous health concerns (including that it is a "probable carcinogen"), as well as the residues that are in our food (and allowed to be there). A new product called Roundup, but containing acetic acid instead of glyphosate, is now available at garden centers in Austria. The product is called Roundup AC is being manufactured by Scotts (the name is licensed from Monsanto), and it uses 10% acetic acid in place of glyphosate. To use ordinary vinegar as a weed-killer: Use on a hot sunny dry day. Just spray or pour some on the offending weeds - and whatever the vinegar touches will soon die. Unfortunately the weeds may come back after a week or two (the root systems may not be killed off) - so just reapply vinegar. Or can make the effects of the vinegar stronger by adding one cup salt to a gallon vinegar or a little (a teaspoon or more) dish detergent to the vinegar. Or combine all three ingredients when needing permanent removal of vegetation from an area such as sidewalk cracks or gravel driveways.

How to use vinegar as a weed killer.

How to use vinegar as a weed killer.Vinegar is a natural product, usually derived from grain, apples or grapes. It is distilled through a fermentation process. The vinegar you buy is typically labeled at 5% acidity. This means it contains 5% acetic acid, the active ingredient.

 Acetic acid is what makes vinegar a weed killer. Actually, it makes vinegar a plant killer. Acetic acid, from any source, will kill most vegetation because it draws all the moisture out of the leaf.Vinegar can also be used to promote growth of plants in drought regions. It is fast.

 Spraying full strength vinegar on a plant in full sun will often result in a withered, brown plant in only a few hours, for sensitive weeds, or by the next day in tougher plants.  This is because it is non-selective, meaning it might kill everything it touches.


This limits the usefulness of a vinegar weed killer, to the extent that you are able to control over-spray that would get on desirable plants.

How to make money holding grain. #‘Money to be made holding grain’

How to make money holding grain. #‘Money to be made holding grain’ On-farm grain storage can improve harvest efficiency but also aids marketing. There’s money to be made by holding grain,” says Weakley County, Tenn., farmer Jason Yarbro. But that’s not the only reason Jason, his brother James and their two sons built facilities with storage capacity of 915,000 bushels of corn, soybeans and wheat and why they are looking to add more capacity. The main storage facility,designed by GSI, handles 915,000 bushels, says Jason, 50. Jason said these bins perform increasingly important roles on the corn, soybean and wheat farm. For one thing, on-farm storage improves harvest efficiency, allowing combines to continue running while a fleet of trucks haul grain and beans the short distance to the bins. “We also harvest corn at 25 percent moisture and dry it to 16 percent in the bins,” Jason says. “We get better yields by harvesting at higher moisture.” He explains that shelling the corn early decreases late-season field losses. “Our final yield is better because of the ability to harvest early, dry and store it.

How to generate clean energy/electricity from water hyacinth.

How to generate clean energy/electricity from water hyacinth. Biogas is a clean and environment friendly fuel produced through the anaerobic digestion of organic wastes such as: cow-dung, vegetable wastes, municipal solid waste and industrial wastewater . It is increasingly be-coming important in domestic and industry as fuel due to its costs and cleanliness. The main component of the gas is methane, carbon dioxide, hydrogen, nitrogen and hydrogen sulphide [3]. Water hyacinth can be used as a potential feedstock for biogas production due to its abundance and high carbon-nitrogen ratio. This study aims at evaluating the potential of utilization of water hyacinth for biogas production.

Poultry litter digestion: how to turn poultry waste to wealth.

Poultry litter digestion: how to turn poultry waste to wealth.The anaerobic digestion of animal and organic wastes has long been known to reduce odors and to have the capability of CH4 production, with the subsequent conversion of the CH4 into electricity, bioCNG or heat. This has been accomplished on thousands of digesters utilizing cow, pig, and human wastes throughout the world. DVO has developed a digester system that uses the processed waste (digestate) after the digester, and after this digestate has gone through a solids separation system. The solids separation system reduces the total solids content of the digestate so that this effluent water is suitable for dilution of the high solids content poultry manure. The practice of solids separation is well-proven on DVO digesters.
