Researchers have unearthed a ‘biological switch’ which could boost crop yield worldwide.
For years, conventional wisdom has held that roots dont grow as deep in hard soil because its just too difficult for them to physically push through it. But our new research has unearthed another reason: their growth is controlled by a biological signal which can be switched off, enabling them to punch through compacted earth.
