Managing Potassium for Organic Crop Production by Robert Mikkelsen an Adequate K Supply Is Essential for Both Organic and Conventional Crop Production
NORTH AMERICA Managing Potassium for Organic Crop Production By Robert Mikkelsen An adequate K supply is essential for both organic and conventional crop production. Potas- sium is involved in many plant physiological reactions, including osmoregulation, protein synthesis, enzyme activation, and photosynthate translocation. The K balance on many farms is negative, where more K is removed in harvested crops than is returned again to the soil. An overview of commonly used K fertilizers for organic production is provided. otassium is an essential nutrient for plant growth, but it often receives less attention than N and P in many crop Pproduction systems. Many regions of the U.S.A. and all of the Canadian provinces remove more K during harvest than is returned to the soil in fertilizer and manure (Figure 1). In the U.S.A., an average of only 3 units of K is replaced as fertilizer and manure for every 4 units of K removed in crops, resulting in a depletion of nutrients from the soil and increasing occur- rences of deficiency in many places. Potassium is the soil cation required in the largest amount by plants, regardless of nutrient management philosophy. 1,400 Removal 1,200 Hay and forage crops can remove hundreds of pounds of K from the soil Manure each year, placing a heavy demand on soil resources. 1,000 Fertilizer Large amounts of K are required to maintain plant health 800 and vigor. Some specific roles of K in the plant include os- moregulation, internal cation/anion balance, enzyme activa- 600 tion, proper water relations, photosynthate translocation, and 400 protein synthesis. -

The Chiba System 千葉方式 ： a Non Toxic Alternative to the Dichromate
The Chiba System 千葉方式 A Non Toxic Alternative to the Dichromate Processes January 2007 Halvor Bjoerngaard Graduate School of Science and Technology CHIBA UNIVERSITY （千葉大学学位申請論文） The Chiba System 千葉方式 : A Non Toxic Alternative to the Dichromate Processes or The Production of Photographic Prints in Permanent Pigments by Utilising the Sensitivity of the Ferric Salt to the Spectre and Employing the Polymerization of Colloids. 2007年1月 千葉大学大学院自然科学研究科 情報科学専攻画像科学 Halvor Bjørngård Abstract This study has the main purpose of presenting a non-toxic, or an alternative, printing system for the dichromate based pigment processes. The two methods presented in depth are modelled on first Carbon printing then Gum Printing. Achieving non-toxicity for these systems means replacing the dichromate sensitizer and secondly to avoid the practise of hardening the substrate. An alternative sensitizer is presented and hardening is avoided by using modified working methods. The chemistry utilised for this purpose is iron based, red-ox induced, free radical polymerization. The sensitizer is ammonium ferric citrate, using either hydrogen peroxide or ammonium persulphate as developer. For Carbon Printing a solution to both the need for hardeners and the problem of oxygen inhibition, which is usual for this kind of polymerisation, is achieved. This is done by using a covering layer of agar-agar that blocks oxygen and changes the transfer system, obsolescing the use of hardeners. For Gum Printing two methods are presented. One is based on gelatine, which allows the use of a hydrogen peroxide bath for development. The second method is with gum arabicum, which necessitates inclusion of ammonium persulphate in the coating as a developing agent. -
Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only. -
