The huge hike in fertiliser prices has prompted DEFRA to set up an Industry Fertiliser Roundtable, chaired by Farming Minister Victoria Prentis. The group will discuss the impact a shortage of fertiliser will have on UK farms and also look at alternatives. We hear from one company working on just that - CCM Technologies makes pellets of fertiliser out of products like manure or digestate, combined with waste carbon dioxide and ammonia from industry.

A farming trial backed by the Welsh Government has found that applying fertilisers enhanced with selenium and sulphur can increase grass yield by up to 11%. Tests were carried out on three farms in Wales, where soils are often deficient in those minerals.

And until now, exports of Scotch whisky to Australia have been subjected to a 5% tariff. But the new UK-Australia Trade Deal will see that removed - so how are distillers responding to the change?
