It’s two for the price of one at next month’s SciBar, when the joint presenters will be Anthony Clarkson, a local arable farmer, farming over a thousand acres in Cheshire and providing services (spraying etc.) to other local farmers, and Andy Roberts who works closely with Anthony as an agronomist.

Anthony will open with a session on technology in agriculture, for example the use of GPS, and Andy will cover the chemistry and husbandry of growing the crop.

Although neither is an experienced speaker they are both well informed about the controversies involved in striving to improve the amount and quality of food production. They therefore speak from practical authority and will welcome questions and discussion about how the need to feed the world can be achieved.
