Book Description
Work in partnership with nature to nurture your soil for healthy plants and bumper crops - without back-breaking effort! Have you ever wondered how to transform a weedy plot into a thriving vegetable garden? Well now you can! By following the simple steps set out in No Dig, in just a few short hours you can revolutionize your vegetable patch with plants already in the ground from day one! Charles Dowding is on a mission to teach that there is no need to dig over the soil, but by minimizing intervention you are actively boosting soil productivity. In fact, The less you dig, the more you preserve soil structure and nurture the fungal mycelium vital to the health of all plants. This is the essence of the No Dig system that Charles Dowding has perfected over a lifetime growing vegetables. So put your gardening gloves on and get ready to discover: - Guides and calendars of when to sow, grow, and harvest. - Inspiring information and first-hand guidance from the author - “Delve deeper” features look in-depth at the No Dig system and the facts and research that back it up. - The essential role of compost and how to make your own at home. - The importance of soil management, soil ecology, and soil health. Now one of the hottest topics in environmental science, this "wood-wide web" has informed Charles's practice for decades, and he's proven it isn't just trees that benefit - every gardener can harness the power of the wood-wide web. Featuring newly- commissioned step-by-step photography of all stages of growing vegetables and herbs, and all elements of No Dig growing, shot at Charles’s beautiful market garden in Somerset, you too will be able to grow more veg with less time and effort, and in harmony with nature - so join the No Dig revolution today! A must-have volume for followers of Charles Dowding who fervently believe in his approach to low input, high yield gardening, as well as gardeners who want to garden more lightly on the earth, with environmentally friendly techniques like organic and No Dig.

Book Description
Tree species are indispensable to support human life. Due to their long life cycle and environmental sensitivity, breeding trees to suit day-to-day human needs is a formidable challenge. Whether they are edible or industrial crops, improving yield under optimal, sub-optimal and marginal areas calls for uni?ed efforts from the s- entistsaroundtheworld. Whiletheuniquenessofcoconutaskalpavriksha(Sanskr- meaning tree-of-life) marks its presence in every continent from Far East to South America, tree crops like cocoa, oil palm, rubber, apple, peach, grapes and walnut prove their environmental sensitivity towards tropical, sub-tropical and temperate climates. Desert climate is quintessential for date palm. Thus, from soft drinks to breweries to beverages to oil to tyres, the value addition offers a spectrum of pr- ucts to human kind, enriched with nutritional, environmental, ?nancial, social and trade related attributes. Taxonomically, tree crops do not con?ne to a few families, but spread across a section of genera, an attribute so unique that contributes immensely to genetic biodiversity even while cultivated at the commercial scale. Many of these species in?uence other ?ora to nurture in their vicinity, thus ensuring their integrity in p- serving the genetic biodiversity.

Book Description
This third edition includes summaries at salient points within the first six chapters, dealing with the principles and practice of vegetable seed production. A suggested further reading list is provided at the conclusion of each of the 16 chapters. The general updating of this third edition has included more detail on 'organic' seed and its production, and also considerations on genetically modified organisms. The increased links between vegetables produced from true botanical seed and those predominantly propagated vegetatively (i.e. the resulting planting material which is often referred to as 'seed') have been added to this edition in Appendix 1.
