Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6–14.0 tonnes of dry, retted stalks per hectare (1–5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha. Only a part of that is bast fiber. Around one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha. The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age." "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.
Hemp seed has a modest content of calcium, which is a necessary element in the creation and strengthening of bones, and also helps to repair the damaged bone matter. Furthermore, the positive boost of calcium which you get from hemp seed and its oil will help you reduce your chances of developing conditions like osteoporosis, arthritis, and help in improving joint health.
France is Europe's biggest producer (and the world's second largest producer) with 8,000 hectares (20,000 acres) cultivated. 70–80% of the hemp fibre produced in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% was used in the automotive sector, and 5-6% was used for insulation mats. About 95% of hurds were used as animal bedding, while almost 5% was used in the building sector. In 2010/2011, a total of 11,000 hectares (27,000 acres) was cultivated with hemp in the EU, a decline compared with previous year.
As far as the nut and seed world goes, hemp seeds are like the straight-A student who's also captain of the football team. A couple of spoonfuls of hemp seeds packs a serious amount of essential nutrients, they're easy to eat and cook with, and they have a pleasantly nutty taste, like a cross between a sunflower seed and a pine nut. And no, they won't get you remotely high. Here's everything you need to know about how to buy and eat these little seeds.
Reality: Hemp oil is an increasingly popular product, used for an expanding variety of purposes. The washed hemp seed contains no THC at all. The tiny amounts of THC contained in industrial hemp are in the glands of the plant itself. Sometimes, in the manufacturing process, some THC- and CBD-containing resin sticks to the seed, resulting in traces of THC in the oil that is produced. The concentration of these cannabinoids in the oil is infinitesimal. No one can get high from using hemp oil.
Consuming hemp seeds is absolutely safe and there are no known side effects of consuming them. However, you should always remember that excess of anything is bad, so make sure that you consume just enough so as to give you a healthy body. Hope, after reading all the hemp seeds health benefits, you would take good care of your health and start consuming hemp seeds even if you don't like them.
Concrete-like blocks made with hemp and lime have been used as an insulating material for construction. Such blocks are not strong enough to be used for structural elements; they must be supported by a brick, wood, or steel frame. However, hemp fibres are extremely strong and durable, and have been shown to be usable as a replacement for wood for many jobs, including creating very durable and breathable homes. The most common use of hemp lime in building is by casting the hemp and lime mix while wet around a timber frame with temporary shuttering, and tamping the mix to form a firm mass; after the removal of the temporary shuttering, the solidified hemp mix is then ready to be plastered with a lime plaster.
Hemp jewelry is the product of knotting hemp twine through the practice of macramé. Hemp jewellery includes bracelets, necklaces, anklets, rings, watches, and other adornments. Some jewellery features beads made from crystals, glass, stone, wood and bones. The hemp twine varies in thickness and comes in a variety of colors. There are many different stitches used to create hemp jewellery, however, the half knot and full knot stitches are most common.
Hemp crops are tall, have thick foliage, and can be planted densely, and thus can be grown as a smother crop to kill tough weeds. Using hemp this way can help farmers avoid the use of herbicides, gain organic certification, and gain the benefits of crop rotation. However, due to the plant's rapid and dense growth characteristics, some jurisdictions consider hemp a prohibited and noxious weed, much like Scotch Broom.
Hemp seeds have long been prized as a high-quality source of plant-based protein and omega fatty acids. A single serving of hemp seeds, about two heaping tablespoons, provides 10 grams of protein and 10 grams of omegas. Hemp also packs in all nine essential amino acids, which we need to get through diet since our bodies don't produce them naturally. Hemp seed oil, which is the oil derived from pressed hemp seeds, contains the most essential fatty acids of any nut or seed oil. Of the three main hemp products on the market—seeds, oil, and protein powder—hemp seeds will provide the broadest spectrum of nutritional benefits per serving.
The process to legalize hemp cultivation began in 2009, when Oregon began approving licenses for industrial hemp. Then, in 2013, after the legalization of marijuana, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century. After that, the federal government created a Hemp Farming Pilot Program as a part of the Agricultural Act of 2014. This program allowed institutions of higher education and state agricultural departments to begin growing hemp without the consent of the Drug Enforcement Agency (DEA). Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014. Hemp production in North Carolina resumed in 2017, and in Washington State the same year. By the end of 2017, at least 34 U.S. states had industrial hemp programs. In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.
Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use, while C. sativa subsp. indica generally has poor fiber quality and female buds from this variety are primarily used for recreational and medicinal purposes. The major differences between the two types of plants are the appearance, and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes, although they can also be distinguished genetically. Oilseed and fiber varieties of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, hemp contains below 0.3% THC, while cultivars of Cannabis grown for medicinal or recreational use can contain anywhere from 2% to over 20%.
A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles. The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen and Volvo. For example, the Lotus Eco Elise and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).
There are no known allergic reactions to hemp seed, but the contact that the seeds may have had with THC-covered plant parts could result in small residues of THC on the seeds. This means that you could possibly experience the feeling of being “high” or under the effect of the psychotropic chemical. This effect of hemp seed is quite rare and isn’t harmful, but it can be an uncomfortable feeling if not anticipated.
