We use two graphs to display the data on the website... As more information is collected over a wider range of seasons we believe that confidence levels in their use will increase... Table 2 below details some of the areas we believe probes can play an important role...

Rural Management Strategies consultant Chris Minehan says using Yield Prophet and plant available water capacity mapping to manage nitrogen can be more profitable than applying a blanket rate... Recent research conducted by Rural Management Strategies in New South Wales has found that managing nitrogen separately across varying soil types using Yield Prophet and plant available water capacity (PAWC) mapping can be more profitable than applying a blanket rate of nitrogen due to savings in fertiliser costs... During the 2013 and 2014 winter cropping seasons, the Grains Research and Development Corporation (GRDC) funded trials at Barmedman to demonstrate the use of Yield Prophet and PAWC mapping to improve nitrogen decision-making in wheat and canola...

Previous studies have shown that values of EC t obtained in this way correlate closely with soil water accumulated to depths of 90cm or deeper... Figure 3 shows data for a field near Warra, Qld where EC t was used to estimate soil water to a depth of 90cm... Side-by-side comparison (Huth et al, 2012) of EM38 with neutron probes have shown that the EM38 is able to explain well over 90% of the variation in soil water measured with probes, but without the need for access tubes or radioactive sources, and with a much smaller time requirement...

Not only do summer weeds rob growers of valuable soil moisture and nitrogen, recent research suggests it is also robbing growers of substantial profits through large yield losses... New South Wales Department of Primary Industries research and development agronomist Colin McMaster has led much of the research into the effects of summer weeds on plant available water and nitrogen in following crops and the yield benefit from controlling summer weeds... Temperature, moisture and organic carbon percentage are key drivers for nitrogen mineralisation a great opportunity for growers to build free nitrogen during the summer months when seasonal conditions allow...
