Download or read book Crops as Enhancers of Nutrient Use written by R Duncan and published by Academic Press. This book was released on 2012-12-02 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crops as Enhancers of Nutrient Use examines the various plant and soil factors that contribute to nutrient use efficiency of plants. It attempts to address policies regarding Low Input Sustainable Agriculture (LISA), conservation-oriented cropping systems, and reductions in environmental contaminants. It also presents longer-term remedies to some of the inherent problems of high volume applications of expensive fertilizer nutrients. This book emphasizes plant-soil interaction, particularly, nutritional interactions involving rhizosphere, microbes, and stress on the root system. Stress factors include moisture and low and high pH. The book also covers the genetic and physiological response of plant to nutrients at the cellular level, on a whole-plant basis, and when subjected to stress. This book will contribute to the development of a more cost-effective and judicious nutrient usage of major crops.

Download or read book Estimating Fertilizer Requirements written by J. D. Colwell and published by Oxford University Press, USA. This book was released on 1994 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers apply fertilizers to crops in order to produce maximum economic return. To attain this, it is important that fertilizer requirements can be estimated accurately. The prevention of excessive use of fertilizers on economic grounds also has the beneficial consequence of minimizing environmental pollution of groundwaters through the leaching of unused fertilizers. This book is intended for both the agricultural scientist who is engaged in research on the use of fertilizers in crop production and consultants who might assist with the interpretation of statistical data. Relevant mathematical and statistical procedures are described critically, indicating their basis and limitations, and how they may be used or misused. Some basic knowledge of statistics is assumed on the part of the reader. Many of the procedures have been developed by the author from experience in soil fertility projects in Australia, Canada, the USA and a number of less-developed 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 Soil and Fertilizer Concepts and Practices written by 楊秋忠 and published by Airiti Press. This book was released on 2015-01-14 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture builds upon the integration of crops and the environment, with which its yield depends strongly on a healthy soil foundation. With that in mind, the knowledge of the soil and fertilizer is crucial to maintaining an environment with optimal nutrients, water and oxygen for crop production. Soil is one of human's precious resources, the protection and nurturing of our soil is thus an integral part of sustainable development. Effective soil management is considered not only a technology, but also an art. In practice, to make use the full potential of the land, the management strategies need to take account of the differences and characteristics of the soil, plant and climate that are unique to each geographical location. Such an approach is increasingly more important nowadays because of the increasing loss of cultivable land and need of high quality agricultural products.
