Preparation of Fertilizers Containing Micronutrients


Book Description

It is hoped that this paper will bring to the reader's attention the fact that the mode of addition of micronutrient materials of fertilizers is a factor that can have a significant influence on both the physical and chemical properties of the mixture. It should become obvious that, in adding micronutrient materials, due consideration must be given to such factors as the chemical compatibility of the ingredients, the segregation characteristics of the mixture, solubility in liquid systems, and the uniformity and density of micronutrient distribution sites that will result from field application of the mixture. While the review of addition methods now in use included here should serve as a useful guide, it is hoped that the reader, on becoming aware of the problems, will be stimulated to contrive improvements and modifications in methods that will fit his own needs.

Plant Nutrition of Greenhouse Crops


Book Description

Greenhouse cultivation is noted for its high uptake of minerals, consistent climatic conditions, exclusion of natural precipitation and control of salt accumulation. Acknowledging that plant nutrition in greenhouse cultivation differs in many essentials from field production, this volume details specific information about testing methods for soils and substrates in a greenhouse environment. It does so while offering a universally applicable analysis. This is based on the composition of the soil and substrate solutions, methods for the interpretation of tissue tests, and crop responses on salinity and water supply in relation to fertilizer application. Fertilizer additions, related to analytical data of soil and substrate samples, are presented for a wide range of vegetable and ornamental crops. The subject is especially apt now as substrate growing offers excellent possibilities for the optimal use of water and nutrients, as well as the potential for sustainable production methods for greenhouse crops.




Micronutrients in Tropical Food Crop Production


Book Description

The mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture. The principal aim is to ensure that fertilizer technology is not a limiting factor to food production in those regions. Although the full extent to which deficiency of micronutrients hampers food production is yet un known, there is ample evidence that problem areas exist and more will be identified as crop production is intensified and marginal lands are exploited. Therefore, it seems fully appropriate at this time that IFDC, as an international organization, take a leadership role in developing micronutrient fertilizer technology appropriate for the tropics and subtropics. The gravity of micronutrient deficiency as a limiting factor to crop pro duction varies from crop to crop and from soil to soil. The effects may range from slight yield reductions to complete crop failure. While the economic impact of omitting micronutrients in seriously affected areas (e.g., Zn in Brazilian Cerrado) is convincing, it is difficult to estimate the yearly loss in crop production due to unsuspected micronutrient deficiency. Active soil and crop testing programs in regions with advanced agricultural systems are aimed at recognizing micronutrients as a limiting plant nutrient in time to allow corrective measures and prevent yield loss. Successful micronutrient monitoring systems are generally limited to developed economies or to developing economies producing export cash crops.

Micronutrient Deficiencies in Global Crop Production


Book Description

A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book. This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.




Nanofertilizer Synthesis: Methods and Types


Book Description

Nano-Fertilizer Synthesis and Types?discusses the production of a variety of nano-fertilizers, including biological, chemical, and mechanical types. Nano-fertilizers aid in nutrition control by increasing nutrient consumption efficiency as nutrients are bonded to nano-dimensional adsorbents, which in turn release nutrients considerably more slowly than traditional fertilizers. As the nano-fertilizer sector advances, one approach is to concentrate on macro elements (N, P, K), as switching to nano-fertilizers may result in significant environmental benefits by replacing the majority of these nutrients. Furthermore, the biosynthesis of nanomaterials employing bacteria, algae, yeast, fungus, actinomycetes, and plants has opened up a new field of study for the creation of inorganic nanoparticles as environmentally benign fertilizers. Because of the several-fold increase in the surface-to-volume ratio of nano-forms of nutrients, and their appropriateness for foliar application, where environmental losses are further decreased, nano-fertilizers may achieve higher efficiency. However, before nano-fertilizers are manufactured and commercialized, further research should be conducted to assess their impact for both humans and the environment. While there are some nano-fertilizer products available, the nano-fertilizer production industry still requires additional public and private sector support and development. Nano-Fertilizers Synthesis and Types presents the latest information, highlights the benefits and impacts of each, and provides a single-volume resource to help effectively and efficiently identify options based on use-case. Exploring the topic from the various mechanistic types to the relevant regulatory, safety, and economic aspects, this volume will be appropriate for those working with and researching new nano-fertilizers. - Guides in the identification of appropriate nano-fertilizer options based on use-case - Addresses both target plant and environmental considerations - Includes economic and regulatory insights
