By-products from the beer industry and agriculture have been shown to reduce the number of root-knot nematodes and increase crop yields.

The mass use of smoked chemicals in agriculture has been proven to be harmful to human health and the environment. And therefore it is forbidden to use it.

Now, in an effort to reduce waste from the agricultural industry and reduce the use of hazardous chemicals. The researchers examined the use of organic byproducts from brewing and farming as a potential method for removing soil impurities. Maintain healthy soil microorganisms. and increase crop yields

In this study published to Frontiers in sustainable food systemsResearchers from the Neiker Basque Institute for Agricultural Research and Development in Spain investigated the use of rapeseed cakes, agricultural by-products, and beer bagasse. “Rapeseed cake and beer bagasse are two possible organic treatments,” lead author Maite Gandariasbeitia explains, along with fresh cow dung. This has shown very positive results in previous studies.

Their high nitrogen content promotes the activity of beneficial microorganisms in the soil. This helps decompose organic matter such as manure and kills nematodes and other parasites. that destroys the crops.”

Gandariasbeitia Also highlighted how nematodes can negatively affect plant yields: “Root nematodes are a common type of soil parasite that penetrates the root tissues of plants to lay eggs, and this activity causes gallbladder or knot-like swelling on the roots. ,” she said.

“This damage has a negative effect on root development. And this means that plants are unable to get nutrients efficiently. slow down plant growth and finally resulting in lower yields for farmers.”

to remove soil impurities and reduce the number of these nematodes Bagasse, beer, and rapeseed cake were combined with the soil with fresh cow dung as a potential organic treatment. After the first crop after treatment Researchers found that root rot was reduced.

The next step for research

The plots also showed a yield increase of approximately 15% compared to the control plot after one year. In addition, organic matter treatment increased the number of beneficial microorganisms in the soil. This was demonstrated by significantly higher soil respiration rates.

Studies show that these agricultural byproducts are effective treatments for ganglion nematodes and other soil parasites for higher yields, as well as promoting sustainable food systems to reduce industrial waste. agriculture Gandariasbeitia Emphasizing that more research is needed to explore other organic treatments that might be used in a similar way: “There are still many questions to answer so we can better understand what’s going on in the soil in during and after biological therapy .

“This can really help us clarify what attributes we should look for in other potential organic treatments to be effective in tackling soil parasitic populations.”
