Researchers demonstrated that using these organic treatments in soils significantly reduced root-knot nematodes and boosted beneficial soil populations, as well as reducing waste from the agricultural industry by incorporating organic by-products as a treatment instead of harmful chemical fumigants.
The use of many chemical fumigants in agriculture have been demonstrated to be harmful to human health and the environment and therefore banned from use.
Now, in an effort to reduce waste from the agricultural industry and reduce the amounts of harmful chemicals used, researchers have investigated using organic byproducts from beer production and farming as a potential method to disinfest soils, preserve healthy soil microorganisms and increase crop yields.
In this study published to Frontiers in Sustainable Food Systems, researchers from the Neiker Basque Institute for Agricultural Research and Development in Spain investigated using agricultural by-products rapeseed cake and beer bagasse (spent beer grains), along with fresh cow manure as two organic biodisinfestation treatments. The lead author, Maite Gandariasbeitia, explains: “Rapeseed cake and beer bagasse are two potential organic treatments which have shown really positive results in previous studies.
