There is opportunity for growers in the HRZ who have soils with a lower water-holding capacity to make more money by potentially planting a summer forage or cover crop without having any impact on the next winter crop... "Examination of soil moisture probe data from a Grain & Graze grazing trial at Lake Bolac conducted from late 2010 to early 2014 would suggest soil moisture is still lost from the soil surface, even with very good weed control and a reasonable amount of stubble cover," Mr Nicholson says... Mr Nicholson says soils with higher clay content have greater potential to lose soil water from capillary rise than sandy, textured soils...

Grain growers in Victoria and South Australia are encouraged to monitor mouse populations and activity before, during and after sowing of this year's winter crops... Mr Henry says mice are still breeding so activity needs to be monitored regularly... The project can't monitor the full extent of mouse activity so Mr Henry encourages growers and advisers to report and map mouse presence, absence and level of activity using MouseAlert ( www.mousealert.org.au ) so others can see the scale and extent of localised mouse activity...

Retain about 70 per cent ground cover, or two tonnes per hectare of cereal stubble cover, to ensure crop yields are not affected in 2014.. To assess stubble load, for every 1t/ha of grain yield about 1.5 to 2.5t/ha of cereal stubble will be left as residue.. Overgrazing stubbles reduces paddock coverage; reducing a soil's ability to store moisture while also increasing the risk of erosion...

Reap winter crop dividends from summer weed management.. John Cameron from ICAN, who co-authored the manual with Andrew Storrie of Agronomo, says weeds in summer fallows rob the next crop of vital sub-soil moisture and nutrients. ".. CAPTION: A crop in which summer fallow weeds were managed (left) and where no fallow weed management occurred (right)...

H. marinum is widely referred to as sea barley grass around the world, and H. hystrixis known as Mediterranean barley grass... Conditions that favour germination and establishment The seed of common sowthistle can germinate at temperatures in the range 5 C to 35 C. Germination is ultimately determined by moisture availability, as a moist environment is preferred... There is a high proportion of seedling emergence from shallow seed sources, whereas more deeply buried seeds remain dormant and long-lived with a half life estimated at 10 years...

Access to at least 60cm of subsoil moisture is a must if farmers are considering planting mung beans as a break crop this summer... "They leave very little stubble which is both good and bad, but it is quite possible to triple crop, going from a winter crop to a mung bean crop and back to another winter crop.".. Mr McIntosh urged farmers to do their research before planting, ensuring they have stored sub-soil moisture, and checking whether their soils have any constraints such as sodium or chloride, or any hard pans that may restrict root development...

Griffith irrigators Paul and Graham Moon have adopted a simple philosophy for coping with the "lottery" of water allocations: "Grow crops which give you plenty of options... Their emphasis is now swinging to winter crops, which they hope will offer enough versatility to cope with unknown water allocations... "We'll be planting a mix of cereals which we can water-out if the water is there, or water-up until the water runs out and then use them for hay, which we sell for export," Paul says. "..

nORTHERn REGIOn Converting rainfall to grain Increasing the amount of water stored in fallows is an important strategy in managing the risks associated with highly variable rainfall in the northern region to improve water use efficiency and potential crop yields... Water use efficiency relies on: the soil's ability to capture and store water; the crop's ability to access water stored in the soil and rainfall during the season; the crop's ability to convert water into biomass; and the crop's ability to convert biomass into grain (harvest index)... Conversion factors for a range of crops and soils are available (see Soil matters under 'Useful resources', page 6); the software program 'HowWet' can be used to estimate PAW during a fallow period from daily rainfall figures input by the user (www.apsim.info); and PAW at the end of a fallow can be estimated directly from fallow rainfall using an estimate of fallow efficiency (FE)...
