ItemLivestock Producer’s Nutrient Management Planner Guidebook: A Waste Management Planning Guide for Pacific Island Livestock Producers(University of Hawaii, 2008-02)This Livestock Producer’s Nutrient Management Planner provides you, the livestock producer, with help in developing an animal waste management plan for your farm. The plan will be unique to each individual farm due to differences in the types of animals you raise, where your farm is located, and how you manage your operation. This workbook is designed to provide the basics on laws and regulations, the concept of nutrient flow through your farm, a series of worksheets to establish the status of your operation, and a guide to developing your farm’s nutrient management plan.
ItemComposted Swine Manure for Vegetable Crop Application(University of Hawaii, 2005-04)One way to manage swine waste is to spread it on agricultural land, but few swine producers have enough land to which to apply all the waste generated by their operation. Crop producers wishing to use swine waste on their land must address issues such as the cost of transporting liquid waste and the limits on waste use imposed by food safety certification requirements. Composting can help address these concerns. Processing the liquid waste by composting it eliminates the need to transport and apply liquids. Food safety certification for vegetable crops does not allow use of raw manure but does allow the use of properly composted livestock waste. Composting thus has the potential to allow the recycling of swine waste nutrients in a sustainable and environmentally friendly manner.
ItemA Portable Dry-Litter Pig Pen(University of Hawaii, 2004-04)The goal of the small-scale swine waste management system described in his publication is to help island communities by developing beneficial uses of pig manure while protecting water resources from being polluted by the nutrients in pig wastes that may run off or leach from pig pens. The portable dry-litter pen system is a practical option for small-scale piggery operations. It adapts the concept of the dry-litter waste management system developed for commercial swine operations in Hawaii, combining it with rotational grazing and cropping strategies and the goal of recycling through composting. The system is relatively inexpensive and adaptable to locations with limited land area. No water is used for pen cleaning, thus reducing the threat of pollution of groundwater supplies and surface water bodies.
ItemComposted Animal Manures: Precautions and Processing(University of Hawaii, 1998-07)Compost is made by recycling organic materials such as yard trimmings, wood chips, food scraps, and animal manures in a controlled process. The process employs microorganisms to transform the raw materials so that they are no longer recognizable. Quality compost is thoroughly decomposed and pathogen-free. The possible presence of pathogenic microorganisms in compost is a major challenge for compost producers. Composted animal manures can be used in many beneficial products, but they must be properly processed. The most important conditions with respect to sanitization are: the composting process must be thorough; the composting process must be complete; and, the finished compost must not be reinoculated with pathogens.
