Soil testing the key to fertiliser strategy.. Subsoil reserves of mineral nutrients such as P have been run down over recent decades, with practices such as direct drill cropping accelerating the loss... Soil testing provides an understanding of your fertility profile and is a vital step in making informed fertiliser decisions...

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)...

Store soil water to help close the yield gap.. Mr Fritsch says to optimise crop yields for 2016, it is important to pay attention to crop variety choice and rotations, input spending, control of weeds, diseases and pests, soil health, stubble cover and fallow management... Mr Fritsch says in some lower-rainfall areas, a high frequency of lower-yielding crops with small margins may be less profitable to grow than a well-planned rotation that includes some crops grown on long fallow during the change between summer and winter cropping...
