Advances in Agronomy, Volume 170, the latest release in this leading reference on agronomy, contains a variety of updates and highlights new advances in the field. Each chapter is written by an international board of authors.

Plants provide the food, shelter, medicines, and biomass that underlie sustainable life. One of the earliest and often overlooked uses of plants is the production of smoke, dating to the time of early hominid species. Plant-derived smoke has had an enormous socio-economic impact throughout human history, being burned for medicinal and recreational purposes, magico-religious ceremonies, pest control, food preservation, and flavoring, perfumes, and incense. In ten illustrated chapters, this global compendium documents and describes approximately 2,000 global uses for over 1,400 plant species. The Uses and Abuses of Plant-Derived Smoke is accessibly written and provides a wealth of information not only on human uses, but also on conservation issues and the role of smoke, fire, and heat in promoting seed germination in biodiversity hot spots. Divided into nine main categories of use, the compendium lists plant-derived smoke's the medicinal, historical, ceremonial, ritual and recreational uses. Plant use in the production of incense and to preserve and flavor foods and beverages is also included. Each entry includes full binomial names and family, an identification of the person who named the plant, as well as numerous references to and other scholarly texts. Of particular interest will be plants such as Tobacco (Nicotiana tabaccum), Boswellia spp (frankincense), and Datura stramonium (smoked as a treatment for asthma all over the world), all of which are described in great detail. In addition, this is one of the first ethnobotanical books to include a section on plant conservation. It addresses issues of over-harvest and invasiveness, the two primary conservation concerns with human-exploited species.

The essays from leading tree scientists collected in In the Circle of Ancient Trees read like fervent love letters to ten of the most ancient and important tree species on the planet … Awe-inspiring.”—Foreword Reviews

This captivating book about dendrochronology—the study of tree rings—uncovers the stories of 10 species of ancient trees, their unique environments and climates, and what they have to tell us about the history of our world.

Ingrained and encrypted in the growth rings of every tree are stories of its environment and the events to which it bore witness. In the Circle of Ancient Trees presents the stories of ten ancient tree varieties in engrossing chapters written by ecologists with specialist knowledge. From the Bosnian pine to the giant sequoia, from the United States, to Europe, to South America, these essays explore how human and environmental history share common roots, while drilling down into the ecology, persistence, and resilience of trees.

Microbiome Stimulants for Crops: Mechanisms and Applications provides the latest developments in the real-world development and application of these crop management alternatives in a cost-effective, yield protective way. Sections address questions of research, development and application, with insights into recent legislative efforts in Europe and the United States. The book includes valuable information regarding mechanisms and the practical information needed to support the growing microbial inoculant and biostimulant industry, thus helping focus scientific research in new directions.
