Failure to meet obligations outlined in a grain contract can be costly to a business, so it is important to have systems in place and manage contracts ... The averages should not be seen as reflecting the overall average price achieved for APW by pool operators... The three key considerations when assessing the forecasting accuracy of a given pool operator is the: n difference between the FPR and the average EPR published during the decision period (i.e. how much less/more did growers receive from what they were expecting)...

The aim of the study was to quantify the economic benefits of PA on six farms across SA... Savings using VRT were calculated from comparing variable rate fertiliser application with a previous "blanket" rate of fertiliser used before PA was employed... Production increases from VRT were calculated from higher yields achieved by increasing fertiliser rates on low fertility areas of paddocks...

Availability of new technologies is rapidly increasing.. Sometimes old technology becomes new again and I refer to the introduction of a disc- seeder into our farming system 5 years ago... I believe that we now have less risk in our system..

Research into the control systems required to make this work is underway including research being conducted at the University of Kentucky by PhD student.. Currently the standard practice for no-till farming systems is to control weeds by applying a uniform rate of herbicide across a field; the chemicals used and application rate determined by the weed species which is the hardest to control... The system is based around a single pair of wires called a "BUS" to which all the computers are connected...

keeping requirements, or for making conditions as measured at the site of decisions about the suitability of conditions Temperature should be measured at a height application... Permanent weather stations will Accurate weather data allow us to compare only provide data that are legally relevant for and contrast individual spray jobs within relative humidity should be measured at 1.25m a pesticide application if they are located at a season and across a range of seasons... Temperature and relative humidity should be measured at a height of 1.25m (avoiding direct radiation onto sensors)...
