Wild plants secrete compounds that would help to avoid using pesticides and fertilizers

A work by CSIC and CREAF scientists highlights that wild plants are more fertile and more resistant to pests than traditional crop varieties because their roots release substances that help them to capture more nutrients and fight pathogenic bacteria and fungi in the soil. If these natural properties were transferred to conventional cultivated varieties, agricultural yield could be improved and the ecological impacts of pesticides and industrial fertilizers reduced.

Thirsty holm oaks lose 21% more carbon through their roots

Once rehydrated, holm oaks have a large capacity for recovery thanks to their high adaptation to the Mediterranean climate. The release of organic compounds into the soil represents a considerable loss of carbon for the holm oak and also modifies the microbial community, which may lead to additional effects on the tree.
