The lack of alternatives suggests a need for improving current methods of land application. • Blind Eye Towards the Problem- Public officials, of the national, regional, and local level have tended to ignore possible public health problems associated with biosolids application • Health Concerns - Rural residents attribute health problems to land application sites near their homes. • Public Awareness - The report stated that local citizen groups, namely Blue Ridge Environmental Defense League (BREDL) and Sewage Sludge Action Network (SSAN), provided resources and tools for educating the public on the issue. • Forum/Discussion - More discussion in the form of an educational or alternative technologies forum regarding biosolids land application would be extremely beneficial. • Further Changes Suggested - Broad agreement that some changes are needed to improve biosolids management practices. Production of organic by-products is a natural part of life. Land application of biosolids mimics a natural cycle of returning nutrients into the soil system, but there is a need to define the risks. 9 2015_WWGST_PPT_Template_01.pptx NCAWWA-WEA Spring 2016 NorthWastewater Carolina Global Service Setbacks Team for Class A and Class B Land Application 10 2015_WWGST_PPT_Template_01.pptx NCAWWA-WEA Spring 2016 ConcernsWastewater Global Service identified Team in December 2010 Biosolids Summit (WEF, EPA) • A more fragmented, state-by-state regulatory framework that increasingly drifts from the Federal regulatory baseline • The introduction of more restrictive management practices such as fence-line setbacks and incorporation requirements; increased legal liability • Greater uncertainty around the mid-term viability of technology and programmatic choices • A substantial increase in management costs • Greater complexity associated with obtaining and maintaining management options. 11 2015_WWGST_PPT_Template_01.pptx NCAWWA-WEA Spring 2016 EvolvingWastewater Global Servicenational Team trends especially pertinent to North Carolina: • Volatile organic compound (VOC) emission restrictions in ozone non-attainment areas • More stringent nutrient (especially phosphorus) limitations in discharges to surface waters • Fertilizer product certification requirements • Increasing links between biosolids, solid wastes, and other organic residuals such as animal manures. 12 2015_WWGST_PPT_Template_01.pptx NCAWWA-WEA Spring 2016 WastewaterDespite Global negative Service Team publicity, the world of biosolids marketing is making great progress!

  • Final Report
    1 Final Report Investigation of the Effect of Experimental Milorganite Formulations on Turfgrass Color, Quality and Growth Dr. Doug Soldat University of Wisconsin – Madison, Dept. of Soil Science March 31, 2014 1. Scope and Objective The overall objective of this research was to compare the agronomic and environmental impacts of various experimental Milorganite formulations compared to Milorganite Classic. To accomplish this objective, a field study, a greenhouse study, and various laboratory characterizations were performed. The field study tracked agronomic responses of the Kentucky bluegrass to the various formulations during two growing seasons, while the greenhouse study evaluated the leaching potential of the products. Various characterizations of the fertilizers and soil were performed to evaluate the chemical differences among the fertilizers. 2. Methods and Materials Field Study This research project was conducted at the University of Wisconsin – Madison. The field study site was located at the University’s O.J. Noer Turfgrass Research and Education Facility in Verona, WI. The research was carried out on a Kentucky bluegrass lawn grown on a Batavia silt loam soil. The grass was mowed weekly or as needed at a cutting height of 2.5 inches, and irrigation was applied weekly to replace 80% of reference evapotranspiration (ET) as estimated by an on-site weather station. In July, 2013, regular irrigation was withheld to attempt to identify difference among the treatments in response to drought stress. The study evaluated ten treatments listed in Table 1 which include six (6) different treatments of Milorganite in various compositions of iron and nitrogen (A-F), two (2) treatments with Milorganite and Crystal Green® (G-H), a control treatment with no fertilizer and a treatment with Scotts® Turf Builder® commercial fertilizer.

  • Best Management Practices for the Enhancement of Environmental Quality on Florida Golf Courses
    Best Managementfor the Practices Enhancement of Environmentalon Quality Florida Golf Courses FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION JANUARY 2007 I am pleased to present the new edition of Best Management Practices for the Enhancement of Environmental Quality on Florida Golf Courses. This manual reflects the collaborative efforts of the Florida Department of Environmental Protection, the Florida Golf Course Superintendents Association, the University of Florida and many private sector partners to develop nonregulatory guidelines for minimizing pollution and conserving Florida’s precious water resources. Water conservation is one of our most crucial environmental issues. By adopting and apply- ing the practices recommended in this guide, industry as well as individuals will help pro- tect our natural resources, minimize the need for future regulations, and continue Florida’s commitment to sound environmental stew- ardship. MICHAEL W. S OLE, SECRETARY Florida Department of Environmental Protection These Best Management Practices were born from the desire of Florida golf course superintendents to demonstrate that environmental stewardship is a responsibility that is taken seriously. The Florida Golf Course Superintendents Association wishes to acknowledge the time, effort, and expertise of the staff of FDEP and other regulatory agencies, the University of Florida–IFAS faculty, and other members of the private and public sector who partnered with us to help develop these voluntary guidelines for enhancing the environment on Florida’s golf courses. There is a reason that wildlife gravitates to golf courses even in urban settings, where they serve as greenbelts. Golf courses present opportunities for many diverse wildlife habitats. By following the practices in this manual, the golf course industry will be able to demonstrate the positive contribu- tions that golf courses make to communities across the state of Florida.

  • Using Milorganite® to Temporarily Repel White-Tailed Deer from Food Plots
    Using Milorganite® to temporarily repel w hite-tailed deer from food plots O din L. Stephens1, Michael T. Mengak1, David Osborn1, and Karl V. Miller1 1 Graduate Student, Assistant Professor - Wildlife Specialist, Wildlife Research Coordinator, and P rofessor – Wildlife Management, respectively, D. B. Warnell School of Forest Resources, University of Georgia, Athens, GA 30602 WSFR - Wildlife Management Series No. 2 March 2005 Abstract When deer populations become locally overabundant, deer browsing of wildlife forage plants during early vegetative growth negatively affects food plot establishment, survival, and productivity. Food plot managers would benefit from a repellent, which provided plants with protection from over-browsing, if it were harmless to people and animals, inexpensive, and easy to apply to group plantings. We tested Milorganite® as a repellent for providing wildlife forage plants with temporary protection from browsing by deer. We planted two 0.5-acre (0.2 ha) plots of soybeans (Glycine max) on five rural properties in northern Georgia and monitored them for 37 days. On each property we established one control (no Milorganite®) and one treatment 240 pounds per acre of Milorganite®) food plot, separated by 15 – 325 yards (15-300 m) of natural, unfertilized vegetation. Although intensity of deer browsing varied by property, a broadcast Milorganite® treatment reduced browsing of soybean plants for at least 37 days. Introduction Food plots are widely used by wildlife managers to increase a property’s value to wildlife. These plantings provide supplemental forage to wildlife during periods when native vegetation is lacking in either abundance or nutritional quality. However, because deer often prefer fertilized food plot plants to naturally available plants, over-browsing can damage food plots before they become sufficiently established.

  • Over-Fertilizing Is a Problem Contributing to Stormwater Pollution in the Clinton River. Without Realizing It, Many Landowners
    Over-fertilizing is a problem contributing to stormwater pollution in the Clinton River. Without realizing it, many landowners are applying fertilizers and pesticides when their lawns don’t even need them! When applying fertilizer, it’s important to know when it is needed and when it is not in order to avoid the excess fertilizer from entering the stormdrains and negatively affecting water quality. It is possible to have a beautiful lawn by fertilizing only two or three times a year, or even not at all. If you find you need to fertilize, you may choose to… Apply twice a year: in late spring (late April or early May) and fall (September or October). OR Apply three times a year: in late spring (Memorial Day), early fall (Labor Day) and late fall (Thanksgiving) Pointers for Pesticide Use Correct watering, mowing and fertilizing habits can reduce many pest problems.
