This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

Download or read book Readings In Farming Systems Research And Development written by W. R. Schmehl and published by Routledge. This book was released on 2019-06-26 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection offers a comprehensive view of the commonalities and diversities of the farming systems research and development (FSR&D) approaches being applied around the world. The authors–among the leading practitioners in FSR&D–discuss conceptual frameworks, research methodology, data collection, and several ongoing FSR&D programs. The book is a must for anyone interested in gaining a concise, yet broad view of this new and growing field of research and its importance to small-scale farming in developing countries.

Download or read book Fertilization of Dryland and Irrigated Soils written by J. Hagin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has been learned about the proper and judicious use of fertilizers. Fertilizer application by farmers has grown from an art to a science. As food producers have strived to increase crop yields by overcoming nutrient deficiencies the use of fertil izers has increased dramatically. This has created a large chemical industry capable of supplying the needed plant food elements. A more complete understanding of soil chemistry and plant nutrition has led to greater fertilizer use with improved fertilization methods and crop cultural practices. Improved fertilizer technology has led to the production of more efficient forms of fertilizer. The modem fertilizer industry and with it fertilization practices began in the humid countries of the world. The use of fertilizers in arid and semiarid regions was later in development, although agriculture had its beginning in semiarid and arid regions. The development offertilizer use is parallel to industrial development in various areas of the world.

Download or read book Comparative Experiments with Field Crops written by G.V. Dyke and published by Elsevier. This book was released on 2013-10-22 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative Experiments with Field Crops is a guide on how to organize comparative experiments about field crops. The book is divided into two parts. Part I deals with how to do and interpret field experiments; the planning of field experiments and special considerations to take into mind; the marking out, sowing, counting, and scoring of field crops; and the harvest as well as sampling. Part II covers the statistics involved in field experiments, and include comparisons and degrees of freedom and error; multidimensional geometry; regression analysis; and analysis of covariance. The text is recommended for agriculturists and botanists who intend to make a comparative study on field crops and are in need of a reference.
