Biodynamic agriculture first originated in central Europe but is now practised in farms, vineyards and gardens all over the world. At the heart of the biodynamic approach are the eight preparations -- Horn manure, Horn silica, Yarrow, Chamomile, Nettle, Oak bark, Dandelion and Valerian -- which are often produced by local biodynamic practitioners using well-established recipes. But as the biodynamic approach expands beyond its European origins, its methods have been increasingly adapted to meet the needs and challenges -- climates, fauna, seasons and regulations -- of different regions around the globe. This fascinating book presents the results of a unique study, carried out by the Agricultural Section at the Goetheanum, Switzerland, into how the biodynamic preparations are used in fifteen countries worldwide, including Egypt, Brazil, New Zealand, India and across Europe. The detailed case studies explore how the preparations are modified to suit their locations, as well as offering an insight into the work of each practitioner and how their understanding has evolved over the years. Contributors include Ueli Hurter, Dr. R. Ingold, Dr. M. Kolar, J. Schoenfelder, Dr. A. Sedlmayr and A. van Leewen. This book is a valuable reference into the production and application of the preparations around the world and an inspiring endorsement of how biodynamic principles hold true in such varied environments.

Die moderne boer staan deesdae voor probleme soos koste wat astronomies eskaleer, produkpryse wat val en stygende rentekoerse op grondpryse. Die faktore noodsaak boere om hul sake- en bestuursvernuf uit te brei ten einde te verseker dat die plaas ekonomies bestuur word. Hierdie boek bevat die grondbeginsels van finansiele bestuur, ontleding en beheer.

Agriculture has a small, and declining, importance in employment and income generation within the EU, but a political importance well beyond its economic impact. The EU's common agricultural policy (CAP) has often been the source of conflict between the EU and its trade partners within first the GATT, and then the WTO. In the Doha Round agriculture was again a sticking point, resulting in setbacks and delays. The position of the EU is pivotal. Due to the comparatively limited competitiveness of the EU's agricultural sector, and the EU's institutionally constrained ability to undertake CAP reform, the CAP sets limits for agricultural trade liberalization blocking progress across the full compass of the WTO agenda. Therefore, the farm trade negotiation, with the CAP at its core, is the key to understanding the dynamics of trade rounds in the WTO.
The book, written by a political scientist and an agricultural economist, applies theory on ideas to explain how the agricultural sector came to be included in the Single Undertaking that resulted in the Uruguay Round agreements, and how this led to a dynamic interplay between CAP reform and the possibility of further agricultural trade liberalization within the WTO, thereby providing useful insights into international trade relations.

This book reviews recent research and applications of chitin and chitosan, as natural alternatives of fossil fuel products, in medicine and pharmacy, agriculture, food science and water treatment. Chitin and chitosan products are polysaccharides derived from food waste of crustaceans and fungi, and thus are cheap, abundant, sustainable, non-toxic, recyclable and biocompatible. Remarkable applications include food additives and preservation, packaging materials, biopesticides and fertilisers, drug delivery, tissue engineering, bioflocculation and dye removal.

As a byproduct of historical development, there are different, unrelated systems of nomenclature for "inorganic chemistry," "organic chemistry," "polymer chemistry," "natural products chemistry," etc. With each new discovery in the laboratory, as well as each new theoretical proposal for a chemical, the lines that traditionally have separated these "distinct" subsets of matter continually grow more blurred. This lack of uniformity in characterizing and naming chemicals increases the communication difficulties between differently trained chemists, as well as other scientists, and greatly impedes progress. With the set of known chemicals numbering over 42,000,000 (in Chemical Abstracts' data base) and continually growing (about 2,000 new additions every day), the desirability for a unified system for naming all chemicals simultaneously grows. Moreover, in order to meet the requirements of disparate groups of scientists, and of society in general, the name assigned to a given chemical should, not only uniquely describe that substance, but also should be a part of a readily recognizable order for the entire field. For these purposes, a topology-based "bi-parametric" system of nomenclature is herein proposed.
- In this book, a new nomenclature system is proposed
- The new nomenclature is applicable to a three dimensional world, and is internally consistent
- This nomenclature unifies ALL branches of chemistry, removing the need for various presently existing sets of rules

This book deals with agriculture as practiced in ancient Israel from the settlement to the destruction of the First Temple. It describes crops and trees cultivated by the Israelite farmer and the methods and tools used in cultivation. The information is gathered from both literary and archaeological sources, with the Old Testament supplying most of the literary information. The author attributes several innovations to the biblical peasant: large-scale terracing, runoff farming (i.e. irrigation), restoration of soil fertility, and the invention of the beam oil-press. Out of print for some time, Eisenbrauns is pleased once again to make this valuable resource available.
