Cultivar selection The most important factors in the persistence of lucerne cultivars are the resistances to phytophthora root rot and colletotrichum crown rot and the application of appropriate cutting and/or grazing management. Of the cultivars now available for irrigated hay production, the best semi-dormant cultivars are generally more persistent than the best winter-active cultivars. . . . → Read More: Management Factors Influencing Persistence and Production in Lucerne Long-term management for disease control in lawns emphasises good basic turfgrass management practices. These practices include the selection of the best adapted grass for the site, proper site preparation, proper management and the use of pesticides if needed. Site Selection: Environmental conditions vary greatly throughout North America and other countries. Some transition zones are . . . → Read More: Long-Term Turf Management Practices for the Prevention of Turf Diseases The site and soil Farm sizes vary from a few hectares to hundreds of hectares. The average turf farm size in Queensland is 16-17 hectares. Small farms Australia-wide average 9.6 hectares and medium-sized farms 37.7 hectares (Aldous et al., 2007). The land must be able to be levelled to create a plane surface for . . . → Read More: Farm Requirements - Commercial Turf Production a riverbed discoloured by iron deposits along its banks in Colorado, USA. Soluble and bacterial Iron in your water can cause blockages to pipes, discolour leaves and reduce photosynthesis efficiency if used for irrigation. Iron is a common problem in water in many places and levels as low as 0.1mg/L (0.1 ppm) . . . → Read More: Is the Iron in my irrigation water a problem? A key water resources question that every farmer should ask himself is How much water do I need for my property? The annual water needs for a rural property will vary depending on where the property is located, the type and number of livestock held, crops grown and the number of people dependent on . . . → Read More: Assessing your annual water needs Sub surface irrigation makes sense in a dry environment like Australia. In this system sub surface irrigation delivers water direct to a plants root system. It is most effective on permanent plantings such as the Barossa Valley, SA, grape vines in this picture. Subsurface irrigation can be achieved by drip lines buried under . . . → Read More: Sub-surface Irrigation |
