13/04/26: Alternative fertilisers, Capercaillie in the Cairngorms.
The search for fertilisers which don't have to be imported, to lessen the risk of price shocks. Even human urine is being explored as a potential source of nutrients.
War in the Middle East has led to price shocks in fertiliser and fuel for farmers. The situation puts a sharper focus on products already being developed to reduce reliance on imported fertiliser. We hear about two innovations: granular fertiliser produced from byproducts including incinerated chicken droppings, and a fertiliser using nutrients extracted from human urine which is being trialled in a project to grow native trees in Wales.
And, we're touring some of the UK's National Parks this week. Today, efforts to conserve the iconic and charismatic Capercaillie in the Cairngorms National Park.
