The discovery made by a group of Italian researchers coordinated by the Scuola Superiore Sant'Anna of Pisa, which demonstrates how to do without the most used herbicide in the world, glyphosate, is an important step towards a greener and more sustainable agriculture. a comparable if not higher crop yield.

The confirmation comes from the three-year study published in the journal Agronomy for Sustainable Development, which evaluated the effects of sunflower sowing by leaving the residues of a plant called vetch, common in lawns, on the ground.



The researchers, led by Daniele Antichi, have built a 'system' to maximize the services provided spontaneously by nature, introducing some innovations.

Using the vetch cover, in fact, they managed to protect the soil, reducing the presence of weeds and at the same time supplying nitrogen to the sunflower, contributing to its healthy and luxuriant growth.

Using the 'roller crimper' on the vetch (a tool that compresses but does not cut the plants at the base) and without using glyphosate, the sunflower weeds were completely controlled and the crop gave comparable productive and economic results, if not superior, compared to the traditional technique.



"Numerous scientific evidences indicate that glyphosate is not as harmless as it seemed", comments Paolo Bàrberi, one of the authors of the study.

"Residues of this substance are constantly found in soil and water and the herbicide has been included by the International Agency for Research on Cancer (IARC) as a substance suspected of causing tumors. At the end of 2022 the European Union will have to decide on the renewal of the authorization for the use of glyphosate - continues Bàrberi - but it is already evident that we will move towards its progressive restriction: therefore, there is an urgent request for valid solutions, which allow us to free ourselves from the use of this herbicide ".
