Practices to avoid when furrow sowing: Top-dressing all fertilisers before seeding with points or blades. The fertiliser can be lockedup in thrown ridges and less available in dry seasons. Using simazine-diflufenican mixtures post emergence on lupins. Metribuzin/ diflufenican causes less crop damage. Using shallow duplex soils which are prone to waterlogging, especially on the . . . → Read More: Furrow Sowing For Improved Crops And Perennial Pastures On Water Repellent Soils Tolerance to salinity of pasture plants suited to waterlogged areas Highly tolerant: saltwater couch
Moderately tolerant Grasses: , phalaris, fescue, kikuyu, puccinellia, tall wheat grass couch, wimmera ryegrass
Legumes: strawberry clover balansa clover, Lotus spp. For non-saline areas, the tolerance of pastures to waterlogging is shown in Table 1.

Figure 1 Waterlogging (excess water in the root zone) and inundation (surface ponding) greatly reduce pasture growth in winter and early spring in areas with more than about 450 mm of annual rainfall. Often the reduced growth is not attributed to waterlogging, which mainly affects the roots. Waterlogging in the coldest months . . . → Read More: Managing Waterlogging And Inundation In Perennial Pastures It is important to distinguish between stocking rate and grazing intensity. Stocking rate is the number of defined stock units per unit area, usually expressed as DSE/ha (dry sheep equivalent per hectare). Grazing intensity includes a pasture component as well as stock numbers, for example, two paddocks stocked at the same rate but one . . . → Read More: Stocking Rates For Perennial Pastures To have plants with well developed roots to provide energy from the plant for regrowth and to supply plant needs from the soil; and to maintain adequate leaf area allowing plants to trap sunlight. To maximise growth rate after grazing, have plants with a good root system and sufficient residual leaf area. Pasture plants . . . → Read More: The Critical Factors For Regrowth Concerning Perennial Pastures Different grazing habits and dietary preferences affect pasture composition. The effects of sheep or cattle are associated with grazing pressure and the ability of sheep to graze closer and more selectively than cattle. Sheep grazing nutritious or palatable perennial pasture plants in summer and autumn often critically damage pasture plants. Cattle do less damage. . . . → Read More: Grazing Habits And Dietary Preferences For Perennial Pastures |
