ISMS President Greg Seymour invited everyone to the Dutch Mushroom Week in The Netherlands next year.
Sales manager Léon Dumoulin from Dalsem Mushroom Projects then explained the various modern systems being built for the production of Agaricus compost, and designed and engineered by Dalsem; concrete floors, bunkers, tunnels. He emphasised how absolutely vital the details are. “Every single detail counts during construc- tion.” He stated an example from China, where PVC piping was installed under the bunker floor, but savings were made on installing a way of cleaning the pipes, so eventually the essential air flow to the compost was blocked. Eric Vernooij, representative of Lambert Spawn Europa and Champfood, enlightened the audience in the use of supplements to optimise the quality and yield of mushrooms. In China the use of supplements is not yet widespread, but on a global level their use is an estimated total of 55,000 tons a year. “Supplements can lead to 10 to 30% higher production, firmer mushrooms, and better quality and shelf life.” At the same time, Vernooij stressed how important it is to use the appropriate application at the right time, and that carefully mixing supplements through the compost is vital. “Study the disadvantages of supplements too. ‘Learn to walk before you start to run!’ Sure, 1 kg of supplement/m2 increases the yield by 4 kg of mushrooms, but what supplement all boils down to is making already good compost even better.” Mathieu Geurts from casing soil producer BVB Euroveen spoke on the selection and prepa- ration of ‘the perfect casing’. He also offered a lot of basic know-how, such as the primary functions of casing soil: supplying water to the mushrooms, facilitating evaporation, preventing dehydration of compost and creating the optimal conditions for growth. Geurts also discussed
various types of casing soil, peat digging regions and the advantages of superior quality Dutch products.
Finally, Ray Samp went into greater detail about the first flush, water management and harvesting techniques and Smith concluded the presentations with a comprehensive lecture on disease control in mushroom growing, and ‘Integrated Pest Management’, a total approach aimed at safe, more efficient, long-term management. Afterwards, the audience had time to ask the speakers questions. There were numerous questions about composting.
Trade fair
As usual, there was a trade fair parallel to the conference, with some of the stands inside (12) and most outside (50) the hotel. The majority of exhibitors were Chinese companies, such as Guoxin, Zhicheng, Kingfit and GTM, but major western suppliers such as Christiaens, GTL, Dalsem, Lambert, Fancom, AEM, Amycel, Unicorn, Italspawn, Sylvan and Amycel were also represented. There was a great atmosphere and encouraging footfall to the stands, the only ‘problem’ was the humid weather outdoors.
Conference A number of lecturers, including Alexander Khrenov, were invited to speak in the evening of 14 November, on the common theme of inter- national cooperation of the Chinese mushroom growing sector with countries such as Korea, Romania and Russia. Many private dinners were organised in the hotel at the same time. We were invited to a very enjoyable evening with Yuguan (see report in MB73), where other guests included some Dutch suppliers, representatives
