Morel mushrooms are prized edible fungi, but growing them repeatedly in the same soil causes problems because toxic ethylene gas builds up and the soil microbiome becomes unbalanced. Scientists found that a beneficial soil bacterium called Pseudomonas putida can break down the ethylene precursor and improve the soil microbial community, making morels grow better and faster. This natural approach using microbial inoculation offers a practical solution to help farmers overcome these continuous cropping challenges.
