After Lissadell he lectured at the MSc Course in Organic Horticulture at UCC and currently works as an organic farm and garden inspector for the Organic Trust. He has grown a diverse range of alternative and novel food crops mainly from the Andes region in South America for many years. They include vegetables such as oca, mashua, ulluco, maca, yacon, quinoa, amaranth, pepino and tarwi. If the potato from the same origin grows so well in Ireland, then why not other crops from the same area? Some of these food crops have potential health benefits (ideal for people suffering from diabetes – e.g. Yacon) and culinary qualities. After having grown many of these crops in Ireland, Klaus plans to explore their native growing conditions, their cultivation methods and how they are cooked, and try to find food crops with potential in Ireland from different parts of the world.
