Hemp is come out as an unexpected remedy for one of the horticulture diligence ’s hidden environmental harms , thanks to inquiry from gardening professor Jessica Lubell - Brand .
For years , gardeners have swear on a particular land additive to alleviate the growth of a broad variety of plant life , from azalea to blueberries : peat moss . It ’s a coarse ingredient in bag potting soil mixture and is easy to rule at most garden and home supply stores .
" It ’s really concentrated to beat all the good quality of peat moss for turn plant life , " Lubell - Brand says . " It holds water well , and it does n’t decompose too quickly . "
But the environmental costs are high : " It takes many 1000 of years for a peat peat bog to develop , and when it ’s glean , you ca n’t really replace it . "
What ’s more , harvest home peat releases ton of carbon into the atmospheric state and destroys peat bogs — ancient ecosystems that diddle a life-sustaining role in regulating Earth ’s climate .
The peat diligence is facing a dwindling supplying , as well as potential new sale restriction : many countries have fleet or proposed legislation banning the sale of peat to garden consumer , owe to these environmental impacts . Currently , most peat sell in the United States is harvest from bogs in Canada , which is regard similar restrictions .
Lubell - Brand , who specialize in cannabis inquiry , wonder if a fiber promise hemp hurd could mime the property of peat moss , which make it an attractive grime additive . Her research into this question is currently put up by a $ 161,414 Sustainable Agriculture Research and Education ( SARE ) grant .
Have you hurd?Hurd is consider a by-product of the hemp material manufacturing outgrowth , in which the wispy outer fibre of the hemp bow are spin into material or Mexican valium . Inside the root is a compact , woody nub – the hurd – which is often discarded .
Lubell - Brand and her Centennial State - PI , Mark Brand ( also a professor of gardening ) , hypothesize that hurd ’s similar particle size to peat moss could aid it put up some of the same originate effects . They begin deport trials , working with alumnus scholarly person Carla Caballero .
" The results have been moderately hopeful , " Lubell - Brand says . " With our studies with greenhouse crop petunia , we get that you could replace the peat up to 66 % … and still produce a interchangeable market - quality plant , in the same amount of time , with the same rankness . "
Repurposing hemp hurd in this direction , Lubell - Brand points out , carries a double environmental benefit : it divert a huge source of waste from the hemp industry , and it reduces the need for destructive peat harvesting .
Next , the research team will test hurd ’s efficacy with other flora , such as shrubs and tomatoes . As part of the outreach element of this project , the squad will also be producing short - form videos serving as " Reports from the Field , " spreading the full word of hurd to growers and other investigator .
The research squad promise a extremely positive response to the new material . In a pre - trial view , they account , 100 % of growers indicate that they " were extremely or strongly interested in enquiry evaluating sustainable alternatives to peat " and that " the use of hemp hurd , a renewable resource , for plant product would be view favourably by the world . "
As the peat supply runs up against impending restrictions and the limits of the earth ’s dwindling provision , research like Lubell - Brand ’s will be all important to help the horticulture industry weather the oncoming violent storm .
" Some of the largest nurseries in the state – permit ’s say , a 500 - Akko outdoor container production greenhouse – utilize about 17,500 three-dimensional pace of peat each year , " Lubell - Brand say . That ’s over five Olympic swimming pocket billiards full of peat .
