Ehrenfried E. Pfeiffer og Michael Maltas The Biodynamic Orchard Book

This book brings together the best advice for cultivating fruit trees, berries and shrubs using biodynamic methods, with the aim of harvesting healthy fruit free of pesticides. Ehrenfried Pfeiffer discusses the principles of tree biology before describing the measures that can be taken to develop a pest-free orchard without the use of chemicals, including soil preparation, the selection of trees for planting, issues of transplanting and pruning, the application of pastes, green cover crops, and pest control. Michael Maltas ran fruit tree experiments on his biodynamic farm in Missouri for four years. The results are recorded in a highly practical annual spraying schedule for orchards, which is reproduced in this book. A month-by-month calendar gives information on specific methods and controls, based on Maltas's extensive experience. This is an invaluable book with practical advice on all aspects of planning and maintaining a healthy orchard. This is a thoroughly revised and updated combined edition of 'Biodynamic Treatment of Fruit Trees, Berries and Shrubs' by Ehrenfried Pfeiffer and 'Orchard Pest Management and Spray Schedule' by Michael Maltas. Published in association with the Biodynamic Farming and Gardening Association of North America.
