Amaranth to Zai Holes

The online version of Amaranth to Zai Holes has been rehosted within The new presentation includes downloadable chapters and charts.

Published in 1996, this book is based on the first 51 issues of ECHO Development Notes (issue 148 was recently released). The ideas in EDN come from questions or experiences of field workers, the scientific research done in support of their work, and many newsletters from around the world which ECHO’s staff monitor for worthy items. This collection is not intended to be a complete handbook. There are important topics which are not mentioned, and in many cases you are referred to other resources for background information or specialized details. Amaranth to Zai Holes is representative of an effort that is continued and expanded in all ECHO publications and on the website.
