Modern Mushroom Growing 2020 Harvesting: A new comprehensive book by Pieter J.C. Vedder on global mushroom cultivation in 2020. A book in which his more than 60 years of knowledge, practical and international experience, and vision about the contemporary industry are recorded. Supplemented with scientific knowledge and insights he has acquired since his previous English book, published in 1978. A book for all mushroom growers in the world, that will contribute to the further optimization of their business operations. Pieter was the founder and principal of a school where the subject of mushroom cultivation in its full width was educated, but also subjects such as climate control, applied biology, chemistry, and economics. But above all a Training Centre where this theory was supported by a well-equipped modern instruction farm with year-round high production of top-quality mushrooms. And by this, a perfect example and instruction farm for all mushroom growers in the Netherlands and abroad. Pieter was the driving force behind this all, a man with a mission. His book 'Modern Mushroom Growing' was published in 8 different languages. The British Growers Association awarded him for his book and the mushroom courses, with the Sinden Award and stated that the book has found a place on every progressive grower's desk in the UK. He was also a regular speaker at international conferences and was asked for various consultancy projects. This book is an improved and more comprehensive edition of the earlier one, with all aspects of harvesting now being included. The strength of this new book is that it is written, based on the issues and questions faced by nowadays mushroom growers all over the world. It provides answers to their questions based on Pieter Vedder's more than 60 years of experience as dedicated educator, teacher, grower and international consultant with a broad network in growing practice and scientific research. Echoing the British Growers Association, I sincerely recommend that this new book gets a place on every progressive grower's desk in the whole world.
