Type NameDateSummary
Riparian Land Management Technical Guidelines Vol 2: On-ground management tools and techniques (Land & Water Australia)2002These comprehensive guidelines for riparian land management include sections on controlling nuisance aquatic plants, managing snags and large woody debris, controlling stream erosion, using buffers to reduce sediment and nutrient delivery to streams, riparian vegetation management, stock management and wildlife management.
Nutrient deficiencies and toxicities, Chapter 14 in the Farm Monitoring Handbook (Hunt, N. and Gilkes, B.)1992Comprehensive information on monitoring nutrient deficiencies and toxicities including methods and plant and soil testing facilities
Algal Blooms - Water Facts 6 (Water and Rivers Commission)1999Increasingly, algal blooms are a public health concern and an ecological problem in wetlands, waterways (rivers and estuaries) and oceans of south west Western Australia. This Water Facts leaflet describes the algae that live in our surface waters and the problems caused when they grow in excess forming algal blooms and ‘red tides’. Examples are given of some blooms affecting wetlands and estuaries in the south west. The management of algal blooms in the Swan and Canning rivers is described as a case history of a river system under environmental pressure.
Lime and Nutrient Balance Calculator (GRDC)2003Lime and Nutrient Balance (LNB) is a computer software package that calculates the lime required to achieve a target soil pH and the requirement of nitrogen and phosphorus to achieve target yields. A separate nutrient budget indicates whether fertiliser additions over a 10 year crop and pasture sequence are sufficient to maintain the nutrient status of the soil. The software requires inputs to describe a particular crop or pasture, soil type, soil-test information, fertiliser type and amount. It takes account of the nutrients removed in product, leaching losses and soil fixation. It uses monthly weather records supplied with the package and/or actual monthly rainfall supplied by the user. The LNB has been designed for farmers or advisors who wish to gain a quick estimate of the lime and P requirements of cropping and pasture systems and the N requirements of cereal and canola cropping systems.
Soil factors influencing eutrophication. In: Soil Guide - a handbook for understanding and managing agricultural soils. (Weaver W. and Summers, R.)1998Eutrophication is essentially the nutrient enrichment of waterways leading to algal growth. Soils are closely linked to eutrophication processes because their characteristics influence the delivery of soil particles and nutrients to waterways. This report section describes some of the principles of eutrophication and then elaborates on some soil criteria influencing the problem.
Nutrient Loss and Eutrophication. In: "The South-West Hydrological Information Package" (Tille, P.J., Mathwin, T.W. and George, R.J.)2003Eutrophication is a consequence of nutrient loss and refers to the enrichment of water bodies with nutrients. This report section describes methods and management actions which can be taken to reduce the loss of nutrients from agricultural land.
Water Erosion. In: "The South-West Hydrological Information Package" (Tille, P.J., Mathwin, T.W. and George, R.J.)2003Water erosion is the detachment of soil particles and their transport by water. Water erosion is a natural process, but accelerated erosion due to human activities is considered a form of land degradation. This report section details water erosion in the south-west region, and provides management options to control water erosion.
Cracking the nutrient code (Fertilizer Industry Association of Australia)2001These guidelines benefit from the extensive nutrient management experience within the fertilizer industry and provide you with the tools to develop and implement a Nutrient Management Code of Practice for your industry, region or farm. Input has also been sourced from specialists in environmental management systems, and the guidelines are developed on the basis of the principles of the International Management Systems Standard ISO 14001.
Fertiliser Management in DairyCatch Environmental Best Practice Guidelines (Dairying for Tomorrow)2006These Dairy Farming Environmental Best Practice Guidelines relate to fertiliser management and address issues such as record keeping, soil sampling and testing, tissue sampling and testing, choosing the right fertilizer, slow release fertilizer, timing fertilizer application, applying fertilizer and fertilizer buffer zones.
Effluent Management in DairyCatch Environmental Best Practice Guidelines (Dairying for Tomorrow)2006These Dairy Farming Environmental Best Practice Guidelines relate to effluent management. They provide practical environmental best practice for collection of dairy effluent, solids separation, dairy ponds, land applciation, reusing treated effluent, rainwater management, solids storage and separation, sumps, pumps, pipes, sprinklers, laneways, sprinklers, feed sheds and pads and financial analyses.
