A few UK politicians think it’s ‘bonkers’ to replace pictures of great politicians with pictures of great pollinators (bumblebees) and other iconic wildlife on UK banknotes. Maybe a £ coin worth 84p featuring Nigel Farage could celebrate BREXIT. www.theguardian.com/business/202...

Looking forward to getting responsible investors interested in soil next week! The interest I’ve had already has been amazing. Hopefully - more people shouting about soil! More strong evidence! More innovation! More experts trained! Better soils! Learn more and register here: invt.io/1exby873uh1

When is a soil too dry for plants to take up water?

The hydraulics of sandy soils make their ecosystems more sensitive to soil drying.
