The optimum planting time for forage oats is from mid-March to June in southern Queensland, and early April to June in central Queensland... Late planting will hasten maturity and reduce the potential for multiple grazing... Starter fertiliser at sowing is recommended, but should be applied separate to the seed as the fertiliser can damage the seed and reduce its germination (e.g. DAP at 100 kg/ha will provide sufficient nitrogen (N) for establishment and phosphorus for the duration of the crop)...

Raised beds exemplify on-farm adaptation.. Bruce says grower confidence in the raised-bed concept was drawn from lessons learnt in Geelong at South Roxby on former agricultural land where Southern Farming Systems (SFS) established its first trial site... Wheat yields were found to increase slightly on the 20m raised beds; the plants matured unevenly, were difficult to harvest and the wider beds were more expensive to form, Bruce says...

Testing the prototype planter on mungbeans, soybeans, wheat, chickpeas and navy beans, Gary was guided by the idea that a combination of cultivation and raised beds had the potential to lift the soil's moisture content when there is too little rain, and improve drainage when there is too much... Using hoe blades and tynes with spear points to sow crops, Gary observed: "The seed always seemed to be planted into wet ground - behind the spear point... Noting there was soil moisture away from the seed where the hoe blades had cut through the soil, and soil compaction where the spear point had placed the seed, he set about creating a planting machine to overcome these constraints...

Testing of clays is recommended... Dave warns that stock health must be monitored and treated on newly ploughed crops... Peter chose the highest rate of subsoil material of between 200 to 300t/ha of clay rich subsoil to apply to his damaged back paddocks...

Graph two is for a heavy clay Black Vertosol from Spring Ridge; results show the plant available water capacity (PAWC) is 272mm... Rooting depth should be determined through perusal of physical and chemical data and the physical observation of roots and water extraction through soil coring and/or electronic monitoring... Simulation of water storage using the >100 year climate record shows that a short fallow from wheat (assuming a dry soil profile at harvest in November of the previous year) results in a 50% chance of at least 110mm (range of 0-300mm) of water being available for an April planting at Spring Ridge and 80mm (range of 0-180mm) at Nyngan (Figure 8)...

With the X-ray method we can also estimate the soil density, and this shows us that roots grow preferentially in looser parts of the soil... Benefit of work to farmers Our trial results show that, using N fertiliser, the yields experienced when cropping newlycleared land can be maintained on soils that have lost significant amounts of soil organic matter... Sowing rule is not critical, but a rule of 50-70cm of wet soil for wheat and 70-90cm of wet soil for sorghum is suggested...
