This Hands On programme explores how we can improve agricultural production. From innovative techniques such as hydroponics, spiritual approaches adopted from Steiner's philosophy, to methods of tackling devastating crop pests and viruses, the programme highlights some sustainable solutions. Stories covered are: new techniques to combat blight in sweet potato crops in eastern China; latest developments in hydroponics; in Wales, new techniques to improve the yields of popular mushroom varieties; new cheap tests for disease in groundnut crops; the rise in sustainable biodynamic farming in Sweden; and new research aims to combat the Sunn pest in wheat.
