Nitrogen Cycling, Optimization of Plant Nutrition and Remote Sessing of Leaf Nutrients in Wild Blueberries (Vaccinium Angustifolium Ait.)


Book Description

ABSTRACT Cont'd : Hyperspectral remote sensing technologies were used for estimating macro and micro nutrients. This study provides critical information on wavelengths important for nutrient estimation in reflectance spectra (400-2500 nm). The results and inferences from this thesis may be employed to improve crop production, increase economic returns and health of soil and sustainability of wild blueberry production in Nova Scotia.

Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (Us Food and Drug Administration Regulation) (Fda) (2018 Edition)


Book Description

Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition) The Law Library presents the complete text of the Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition). Updated as of May 29, 2018 To minimize the risk of serious adverse health consequences or death from consumption of contaminated produce, the Food and Drug Administration (FDA or we) is establishing science-based minimum standards for the safe growing, harvesting, packing, and holding of produce, meaning fruits and vegetables grown for human consumption. FDA is establishing these standards as part of our implementation of the FDA Food Safety and Modernization Act. These standards do not apply to produce that is rarely consumed raw, produce for personal or on-farm consumption, or produce that is not a raw agricultural commodity. In addition, produce that receives commercial processing that adequately reduces the presence of microorganisms of public health significance is eligible for exemption from the requirements of this rule. The rule sets forth procedures, processes, and practices that minimize the risk of serious adverse health consequences or death, including those reasonably necessary to prevent the introduction of known or reasonably foreseeable biological hazards into or onto produce and to provide reasonable assurances that the produce is not adulterated on account of such hazards. We expect the rule to reduce foodborne illness associated with the consumption of contaminated produce. This book contains: - The complete text of the Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition) - A table of contents with the page number of each section




Dietary assessment


Book Description

FAO provides countries with technical support to conduct nutrition assessments, in particular to build the evidence base required for countries to achieve commitments made at the Second International Conference on Nutrition (ICN2) and under the 2016-2025 UN Decade of Action on Nutrition. Such concrete evidence can only derive from precise and valid measures of what people eat and drink. There is a wide range of dietary assessment methods available to measure food and nutrient intakes (expressed as energy insufficiency, diet quality and food patterns etc.) in diet and nutrition surveys, in impact surveys, and in monitoring and evaluation. Differenct indicators can be selected according to a study's objectives, sample population, costs and required precision. In low capacity settings, a number of other issues should be considered (e.g. availability of food composition tables, cultural and community specific issues, such as intra-household distribution of foods and eating from shared plates, etc.). This manual aims to signpost for the users the best way to measure food and nutrient intakes and to enhance their understanding of the key features, strengths and limitations of various methods. It also highlights a number of common methodological considerations involved in the selection process. Target audience comprises of individuals (policy-makers, programme managers, educators, health professionals including dietitians and nutritionists, field workers and researchers) involved in national surveys, programme planning and monitoring and evaluation in low capacity settings, as well as those in charge of knowledge brokering for policy-making.







The Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stocks


Book Description

Note for the electronic edition: This draft has been assembled from information prepared by authors from around the world. It has been submitted for editing and production by the USDA Agricultural Research Service Information Staff and should be cited as an electronic draft of a forthcoming publication. Because the 1986 edition is out of print, because we have added much new and updated information, and because the time to publication for so massive a project is still many months away, we are making this draft widely available for comment from industry stakeholders, as well as university research, teaching and extension staff.




Plant Litter


Book Description

Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation. The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation. The latest information focuses on three fields: - the effects of manganese on decomposition and possibly on carbon sequestration, - new findings on decomposition dynamics, and - the new analytical technique using 13C-NMR.
