The Potential Rebound of Hemp in Agriculture Hemp (Cannabis sativa L.) is an ancient crop, and one of the oldest domesticated plants known to man, traditionally valued for its tough bast fibres as well as its medicinal properties. Though it is related to commonly known marijuana, typically ingested to achieve a high in the user, hemp has extremely low concentrations of the active chemical in marijuana, THC, and is thus not deserving of the cultivation ban it has endured as a result of this relation. Hemp has in the past been used widely for textiles and cordage as well as paper, with almost all historically significant documents printed on hemp paper. With the invention of techniques for creating paper from tree pulp, and the powerful…show more content…
When the male plants are removed from growth sites, females cannot be pollinated and continue to produce resinous flowers. These flowers can then be harvested, dried and cured, and are valued for their medicinal properties. If the male plants are allowed to remain in fields then this flowering period is relatively short, with extremely low quantities of THC produced. These plants then produce large amounts of seed and greater volumes of fibre, and are commonly referred to as hemp. Hemp plants are hardy and drought resistant, reaching up to five metres tall, with taproots penetrating up to one metre into the soil, and have dense canopies of leaves, which once established grow rapidly and shade out competing weeds, making the use of herbicides unnecessary. Hemp has a natural insecticide called terpene as well, which is responsible for the distinct smell which emanates from the plants and is believed to repel insects (Benhaim, P. 2005). Hemp of the past was grown primarily for its stalk, consisting of both fibre and core, which is also known as shiv. These fibres are among the strongest in the natural world, with traditional nautical uses as cordage, canvas and clothing, as well as paper. The shiv, with its insulative and absorbent properties was used primarily as animal bedding. In more recent times, hemps shivs have also been used as building materials, with applications in anything from concrete alternatives, to
