Download or read book Resource Management in Rice Systems Nutrients written by V. Balasubramanian and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice is the major staple food in Asia, and food security means rice security for most Asians. By the year 2025, we need to produce about 60% more rice than we do today to meet the growing demand. Efficient use of inputs is vital to safely produce the additional food from limited resources with minimal impact on the environment. This book reviews emerging knowledge-intensive technologies and decision aids for improved nutrient management in rice, technology adoption constraints at the farm level, and innovative approaches for field evaluation and promotion of new technologies to farmers. It is highly useful to rice scientists and development workers, students of agronomy, soil science, and plant nutrition, and crop consultants and extension workers in rice all over the world.

Download or read book Soil and Fertilizers written by Rattan Lal and published by CRC Press. This book was released on 2020-05-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Download or read book Micronutrient Fertilizer Use in Pakistan written by Abdul Rashid and published by CRC Press. This book was released on 2022-09-13 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micronutrient research has been an important component of the soil fertility and plant nutrition program in Pakistan since the identification of zinc deficiency in rice in 1969. Since then, considerable progress has been made on diagnosis and management of micronutrient nutrition problems in crops. However, now there is growing R&D evidence that micronutrient malnutrition in humans could be addressed through enriching staple food grains with micronutrients. This book presents the latest R&D information on micronutrient problems in crop plants/cropping systems and their corrective measures. The current status, the constraints, and economic benefits of using micronutrient fertilizers for optimizing crop productivity and soil resource sustainability are discussed along with estimating future potential requirement of micronutrient fertilizers to optimize crop productivity, produce quality, and soil resource sustainability. Wide-scale preventable micronutrient deficiencies in human populations originate from micronutrient-deficient soils over which staple cereals and other food crops are grown. This book summarizes R&D information on fertilizer use-based micronutrient biofortification in staple food grains to address "hidden hunger" in human populations. The book also presents the best management practices by which micronutrient deficiencies could be corrected in crop plants in a farmer-friendly manner. Features Reviews the micronutrients R&D carried out in Pakistan over the past five decades Focuses on soil–plant analysis techniques for effective prognosis and diagnosis of micronutrient disorders Presents spatial variability maps of micronutrient deficiencies in agricultural soils and crops Provides value–cost ratios of using micronutrient fertilizers for major crops Works out current use level of micronutrient fertilizers and their potential future requirements in the country Discusses agronomic biofortification approach for enriching crop-based food with micronutrients to address "hidden hunger" Presents a compelling case for enhanced use of the deficient micronutrient fertilizers to optimize crop productivity, farmer income, and national economy Presents micronutrient fertilizer use recommendations for salient crops and discusses fertilizer use for micronutrients in the context of 4R nutrient stewardship Recommends future R&D needed for optimizing micronutrient nutrition of crops
