  • PSC Technical Advisory Panel Report.Pdf
    National Organic Standards Board Technical Advisory Panel Review compiled by University of California Sustainable Agriculture Research and Education Program (UC SAREP) for the USDA National Organic Program Potassium Sulfate for use in crop production Executive Summary1 The following petition is under consideration with respect to NOP regulations subpart G, governing the inclusion of substances on the National List of Allowed and Prohibited Substances: Petitioned: Addition of potassium sulfate to section 205.601(j), “Synthetic substances allowed for use in organic crop production as plant or soil amendments.” Potassium sulfate is a source of highly soluble potassium, and has the additional benefit of supplying sulfur. It is used in agricultural production systems where potassium is a limiting nutrient and also as a substitute for potassium chloride on chloride- sensitive crops. The NOP has no prior ruling on the use of the substance. The nature of the petitioned substance is highly debatable. Naturally occurring potassium sulfate is not subject to the TAP review process because “naturally-occurring” substances are implicitly allowed for use in organics. The intended sourcing of the petitioned form of potassium sulfate, however, brings into question the interpretive distinctions between a “synthetic” and a “non-synthetic” under organic law. According to the petitioner, the product “should not be treated differently than product produced from natural brines” since it is produced from naturally occurring minerals. The crux of the decision to grant the petition rests on how one chooses to interpret this equivalency claim. All TAP reviewers agreed that the petitioned substance should be considered synthetic. In general, the reviewers also agreed that it should be restricted as a soil adjuvant.

  • Crystal Growing Competitions a Guideline for New Organizers
    Crystal growing competitions a guideline for new organizers A major objective of the International Year of Crystallography is the establishment of a vibrant worldwide network of schools participating in crystal-growing experiments and taking part in national and regional competitions, to introduce students to the exciting, challenging and sometimes frustrating world of growing crystals. To celebrate this initiative, there will be a worldwide competition in 2014, open to all schoolchildren (whether involved in a national competition or not). The winners, will be those who most successfully convey their experiences to the panel of judges through videos, diaries, essays, soundscapes and other media. In this brochure we provide information to teachers and to schools or other organizations who want to join in this exciting venture. For newcomers, the easiest way will be to contact existing national competitions (we provide a list of current ones and an opportunity for new national initiatives to register their interest and involvement). We also provide some basic tips on how to get started with basic crystal-growing experiments. 2 1. Scenario for a successful competition For many years crystal growing competitions have been run successfully in a number of countries. With the help of the IUCr the organizers of these competitions want to share their experience with future organizers. The IYCr in 2014 provides perfect timing to start a new competition in your region or country. We present you with a scenario to do this and offer support in case of questions. Things to decide before... who can participate (age limit? different categories? regional or national) how to register material to crystallize (sponsoring? how delivered? safety) time period (depending on the school year) judging on single crystal quality only, or together with other items (poster, log book, ...) and who will do the judging? The ideal timeline Start your registration early enough, preferably done by the teacher with a electronic registration module.

  • Chemical Resistance Guide EPOXY REPAIR PASTE
    CHEMICAL RESISTANCE GUIDE PROLOGUE Many chemicals, dilutions and solutions that exist in an agricultural, pharmaceutical or industrial environments are alphabetically presented in the following chart. The chemical resistance characteristics has either been derived from laboratory testing (at standard conditions of 77 ±2 °F (25 ±1.1 °C) and 50% relative humidity, in-service/actual field experience or by rating the chemical according to known physical properties or characteristics. Service conditions may be complicated or complex due to a variety of effluent or chemical mixtures at undisclosed concentrations with temperature fluctuations and other unknown or unanticipated conditions at various dwell times that may exist episodically at the specific job site. Applying a test patch or patches prior to choosing & installing a system is always advisable. After the test patches are fully cured, expose them to the anticipated service conditions whether actual or simulated. Test patches will help determine the suitability of your product selection as to the specific service needs and may potentially establish any required cleaning, recoating and/or repair regimen. The system rates the product’s integrity and does not account for weathering resistance, staining or gloss loss.

  • Position Paper on the Use of Potassium Alum in Organic Banana Production
    Forschungsinstitut für biologischen Landbau (FiBL) December 2014 Frick, Schweiz page 1 Position paper on the use of potassium alum in organic banana production Characterization of potassium alum ‘Potassium alum‘ or ‘potash alum‘ are common names for potassium aluminium sulfate. It is commonly found in the hydrate form. Its chemical formula is KAl(SO4)2 · 12(H2O); the CAS number is 7784-24-9. Potassium alum is a naturally occurring sulfate mineral. It is highly soluble in water. Use of potassium alum in banana production Bananas grow in bunches (‘banana stems’), which comprise 3 – 20 tiers (‘hands’), each of which consists of 10 – 20 banana fruits (‘fingers’). For harvesting, the entire bunch is cut off the plant. Then, the bunch is divided into small clusters of fruit (’dehanded’), to facilitate cleaning. Latex will exudate from the wounds where the clusters were cut. If it is allowed to dry on the fruit, it will form dark stains, which give the fruits an unattractive appearance. To prevent this, the clusters are washed in ‘delatexing baths‘. It is generally recommended to add potassium alum to the delatexing baths (Yañez et al., 2004; Anyasi et al., 2013; Gutierrez Gonzales, 2013). This helps remove the latex (Yañez et al., 2004; Anyasi et al., 2013), controls pathogens in the wash water (Anyasi et al., 2013; Gutierrez Gonzales, 2013) and promotes the proper healing of the cutting wound (Yañez et al., 2004; Gutierrez Gonzales, 2013). Proper healing of the wound is important to prevent crown rot. Crown rot is a disease complex caused by several fungi, sometimes in association with bacteria (Hailu et al., 2013).
