Build healthy soil and grow better plants
Robert Pavlis, a gardener for over four decades, debunks common soil myths, explores the rhizosphere, and provides a personalized soil fertility improvement program in this three-part popular science guidebook.
Healthy soil means thriving plants. Yet untangling the soil food web and optimizing your soil health is beyond most gardeners, many of whom lack an in-depth knowledge of the soil ecosystem.
Soil Science for Gardeners is an accessible, science-based guide to understanding soil fertility and, in particular, the rhizosphere - the thin layer of liquid and soil surrounding plant roots, so vital to plant health.
Coverage includes:
Written for the home gardener, market gardener, and micro-farmer, Soil Science for Gardeners is packed with information to help you grow thriving plants.
Robert Pavlis is the owner and developer of Aspen Grove Gardens, a 6-acre botanical garden that features 3,000 varieties of plants. Specializing in soil science, he has been an instructor for Landscape Ontario and is a garden blogger, writer, and chemist. He resides in Guelph, Ontario.

Dateiformat: ePUBKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat ePUB ist sehr gut für Romane und Sachbücher geeignet - also für „fließenden” Text ohne komplexes Layout. Bei E-Readern oder Smartphones passt sich der Zeilen- und Seitenumbruch automatisch den kleinen Displays an. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
