In little more than a decade since the publication of the first edition of Science for Agriculture the
book has become a classic in its field. The book celebrated over a century of contributions by the
United States Department of Agriculture—State Agricultural Experimentation research system to
the growth of production and productivity of American agriculture.
This second edition is much more than an updating of their earlier work.

Detailed assessment of impacts of more than 50 Farmer Field Schools (FFS) in 11 provinces through
which over 2,000 farmers were trained from 2005 to 2006 has shown many beneficial effects. Farmers
have increased knowledge and their skills in planting and protecting citrus trees and at the same time
they have increase awareness of the recording and post-harvest storage, marketing and especially the
changes in farming practices significantly after participating in FFS.
The farmer who has fought "bugs" on crop after crop needs no argument to convince him that insects are serious enemies to agriculture. Yet even he may be surprised to learn that the damage done by them, as estimated by good authority, amounts to millions and millions of dollars yearly in the United States and Canada. Every one thinks he knows what an insect is. If, however, we are willing in this matter to make our notion agree with that of the people who have studied insects most and know them best, we must include among the true insects...
We left the United States from Seattle for Shanghai, China, sailing by the northern route, at one P. M. February second, reaching Yokohama February 19th and Shanghai, March 1st. It was our aim throughout the journey to keep in close contact with the field and crop problems and to converse personally, through interpreters or otherwise, with the farmers, gardeners and fruit growers themselves; and we have taken pains in many cases to visit the same fields or the same region two, three or more times at different intervals during the season in order to observe different phases of the...
About the year 1875 the good times came to an end. The full force of free trade was at last felt. The seasons assisted the decline, and there was now no compensation in the shape of higher prices. In the eight years between 1874 and 1882 there were only two good crops. A new and formidable competitor had entered the field; between 1860 and 1880 the produce of wheat in the United States had trebled. Vast stretches of virgin soil were opened up with the most astonishing rapidity by railroads, and European immigrants poured in. The cost of transport...
In response to a growing need to bridge aspects of geography and ecology, Troll
(1950, 1968) coined the term “landscape ecology,” which was adopted as a new
scientific discipline. According to Troll (1968), the landscape can be studied in terms
of its morphology, classification, and changes in time (history), as well as the
functional relationships between its components, which he called landscape ecology.
Troll also considered that problems of landscape protection as well as management
should be included in geographical analyses of landscapes.
This book aims to strengthen the knowledge base dealing with Air Pollution. The book consists of 21 chapters dealing with Air Pollution and its effects in the fields of Health, Environment, Economy and Agricultural Sources. It is divided into four sections. The first one deals with effect of air pollution on health and human body organs. The second section includes the Impact of air pollution on plants and agricultural sources and methods of resistance. The third section includes environmental changes, geographic and climatic conditions due to air pollution....
Agroecology encompasses not only aspects of ecology and agriculture, but the
ecology of sustainable food production systems, including the technology and
related societal and cultural values (e.g. Gliessman 1998; Altieri and Hecht 1990;
Altieri 1989, 1987, 1983) to better promote healthy and functional environments for
a sustainable quality of life (see also Castillo et al. 2005). To provide effective com
munication regarding the status and advances in this burgeoning field, connections
must be established with many disciplines including (but not limited to)...
The international Cartagena Protocol on Biosafety deals primarily with the agricultural definition but many advocacy groups seek to expand it to include post-genetic threats: new molecules, artificial life forms, and even robots which may compete directly in the natural food chain.Biosafety in agriculture, chemistry, medicine, exobiology and beyond will likely require application of the precautionary principle, and a new definition focused on the biological nature of the threatened organism rather than the nature of the threat.
It is intended that this book be suitable for a variety of engineers and ecologists, who
may wish to gain an introduction to the rapidly growing field of ecological and
environmental modelling. An understanding of the fundamentals of environmental
problems and ecology, as presented for instance in the textbook Principles of
Environmental Science and Technology is assumed. Furthermore, it is assumed that
the reader has either a fundamental knowledge of differential equations and matrix
calculations or has read the Appendix, which gives a brief introduction to these
The book offers comprehensive coverage of the broad range of scientific knowledge in the fields of advances in induction and microwave heating of mineral and organic materials. Beginning with industry application in many areas of practical application to mineral materials and ending with raw materials of agriculture origin the authors, specialists in different scientific area, present their results in the two sections: Section 1-Induction and Microwave Heating of Mineral Materials, and Section 2-Microwave Heating of Organic Materials....
Biofuels are gaining public and scientific attention driven by high oil prices, the need for energy
security and global warming concerns. There are various social, economic, environmental
and technical issues regarding biofuel production and its practical use. This book is
intended to address these issues by providing viewpoints written by professionals in the
field and the book also covers the economic and environmental impact of biofuels.
This text includes 14 chapters contributed by experts around world on the economy, evironment
and sustainability of biofuel production and use.

Reduce overall grain yield by cracking as one of the main problems directly reduces income and the availability of staple food to the farmers in the Mekong Delta. Cracking or fissuring of a grain of wheat that may occur in the rice field by harvest time is not right / real, post-harvest conditions improper drying and milling activities inconsistent. This project aims to improve the quality and value of rice, through an integrated approach that includes the service provider farmers, millers, and extension workers and educational institutions...
