Book Description
El país está enfrentado un tema tan crítico como la apertura económica -tratados recién firmados como el TLC con Estados Unidos- obligan a los gremios del sector productivo a ser más competitivos si quieren continuar en el mercado. Uno de los elementos para mejorar este aspecto es la eficiencia en el uso de los recursos (fertilizantes, riegos, manejo sostenible del medio ambiente, etc.). La toma de decisiones es un paso difícil en cualquier empresa. En la empresa agropecuaria intervienen muchos elementos, componentes y variables que es necesario conocer a la hora de decidir. Como el momento de las decisiones y los resultados están alejados en el tiempo, los problemas se manifiestan cuando suele ser tarde para resolverlos. Así, para tomar buenas decisiones es fundamental una correcta información previa. Un análisis equivocado lleva siempre a un mal resultado; cuando los márgenes de ganancia de la actividad agropecuaria se reducen, el costo del error puede ser crítico. Las buenas decisiones solo pueden ser resultado de un correcto análisis de las variables y esto solo puede hacerse con buena información.

Book Description
This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Book Description
The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Book Description
El incremento de productividad en la agricultura de los países desarrollados ha ido unido al empleo de fertilizantes. En ocasiones el empleo excesivo de los mismos no sólo ha aumentado la productividad, sino que se ha convertido en un problema para el medio ambiente. Por otro lado, en los países en vías de desarrollo, la falta de fertilización es una de las causas por las que no se llega a niveles aceptables de abastecimiento alimentario. En la actualidad, se trata de pasar de una agricultura productivista a otra más eficaz, con menor empleo de insumos para reducir los costes de producción, que a la vez evite daños en el medio ambiente. Con este libro se pretende mostrar los aspectos más importantes de las técnicas de análisis de suelos y plantas y a partir de los datos obtenidos con ellas establecer recomendaciones de abonado en praderas, céspedes, viveros y cultivos forestales.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Book Description
This is the first comprehensive book on Argentinian pedology. It discusses the main soil types of Argentina, their geographical distribution, classification, functions, agricultural use, ecological aspects, and the threats to which they have been subjected during centuries of intensive and extensive management. The description of the soils is accompanied by a complete set of data, pictures and maps, including benchmark profiles and an overview of the country's agricultural production. It also deals with future scenarios of the relationships between soil science and other disciplines and the main challenges that soil science will face in the future. Further, the book explores aspects of the main soil forming factors, such as climate, vegetation, geology and geomorphology, making use of new, unpublished data and elaborations, and presents a history of pedological research in Argentina.

Book Description
The global environment is constantly changing and our planet is getting warmer at an unprecedented rate. The study of the carbon cycle, and soil respiration, is a very active area of research internationally because of its relationship to climate change. It is crucial for our understanding of ecosystem functions from plot levels to global scales. Although a great deal of literature on soil respiration has been accumulated in the past several years, the material has not yet been synthesized into one place until now. This book synthesizes the already published research findings and presents the fundamentals of this subject. Including information on global carbon cycling, climate changes, ecosystem productivity, crop production, and soil fertility, this book will be of interest to scientists, researchers, and students across many disciplines. - A key reference for the scientific community on global climate change, ecosystem studies, and soil ecology - Describes the myriad ways that soils respire and how this activity influences the environment - Covers a breadth of topics ranging from methodology to comparative analyses of different ecosystem types - The first existing "treatise" on the subject
