Precision agriculture (PA) involves a range of methodologies and technologies which aim to improve the precision of agricultural management in spatially-variable fields... The research investigates the potential of using a combination of EMI sensing in conjunction with differential fertilizer management to optimize the match between spatially-variable plant water demand and plant available water...

Potential yield was estimated by a modified French and Schultz approach using monthly rainfall for each site and season... Most sites showed no yield increase in the season of application... A range of grain yield responses to gypsum were measured from a 13 percent decrease to over 100 per cent increase...

The paper aims to examine some of the knowledge gained recently from Grain & Graze activities and look at the current issues and future direction that these crops may take - not only within the crop rotation but also the farming system.. In a year such as 2011 summer rains were generally well in excess of crop requirements and our results show little difference in soil moisture levels following summer crops... A recent survey conducted by the author of approx 20 growers and agronomists in south western Victoria, who had been active with alternate break crops over a number of years, highlig...

Soil Water Crop Planting Triggers and Risk for Central Western NSW.. The results indicate that for soil water quantities of up to approximately 85mm at the decision point, the optimum rotations are either Rotation 3 or 4 (Figure 1)... The above simulations were conducted with the 'full' APSIM model to create crop rotations...

The malt must meet the brewer's set of specifications in terms of its quality performance in the brewhouse; as with the maltster, the brewer is chasing yield and when the brewer buys 100 tonnes of malt he wants to make as many hectolitres of beer as possible... Many brewers operate in highly sophisticated, computerised production factories and require malt of consistent supply, reliable performance and quality, and malt that the brewer is comfortable using. Many breweries make beer in batch sizes of hundreds of hectolitres using significant amounts of raw ingredient, and it is vital to the...

THE VALUE OF FEED GRAIN FOR LIVESTOCK - IT PAYS TO KNOW GRAIN QUALITY.. Both available energy content (MJ/kg) and available energy intake (MJ/day) must be described to fully characterise the energy value of any batch of cereal grain for livestock... A large research effort, the Premium Grains for Livestock Program, funded jointly by the grains and animal research and development organisations and Ridley Agriproducts was established in 1996 to define the range and causes for variation in the quality of cereal grains for different livestock types...

The majority of current wheat varieties need to be sown in the first half of May in order to flower during the optimal period for yield in most environments, which unfortunately coincides with the period of recent rainfall decline... Growers wishing to maximise farm water-use efficiency need to adopt strategies that will allow them to get as much of their wheat crop as possible flowering during the optimal period in their environment... The article reports results from several experiments conducted across southern Australia and farmer experience investigating the potential for earlier sowi...

Costs are increasing and farm businesses must respond appropriately to ensure future competitiveness... Farms need to continue to increase in scale, but maintain outputs per hectare... The following trends outline the cost and income trends for a group of 10 farm businesses in the lower north of South Australia who have been benchmarking their businesses for the last 14 years...

Recent work in DAQ00148 and previous projects has focussed on developing new soil testing strategies (0-10cm and periodic 10-30cm testing to determine P and K status), soil tests (BSES P and tetraphenyl borate extractable K to measure slow release P and K reserves) and critical soil test values to trigger fertiliser application responses... Previous results (Spring 2011 Updates) showed that sorghum responses to P bands were improved when band spacing was 50cm or less, and similar trends have been obtained for K band spacings in the winter wheat crop at Brookstead (Table 2), although differ...

A paddock specific strategy for controlling radish is possible by knowing the resistance genetics present and the stage of resistance development- the expenditure required... We can now describe what is happening within paddocks and can explain why products work or do not work, highlighting the importance of growers knowing what genetics they are dealing with... Best Management Practice is not to rely solely on new chemistries but to use mixtures of both old and new chemistry across populations to minimise selection pressure on all groups...
