It is important to remember that there are many ways in which PA can be adopted and used to make or save money, improve timeliness or environmental management and to carry out onfarm trials... If a grower purchases a GPS unit using one system and then changes to one using the other system, locations will not be translate accurately... Growers are not confident in using the currently available indices in making cropping decisions...

Soil organic matter contributes to a range of biological, chemical and physical properties of soil and is essential for soil health... Soils rarely reach their theoretical potential for organic matter storage (see Figure 1.7)... In soils with low clay content the amount of humus and resistant soil organic matter is increasingly important to nutrient exchange because its large surface area gathers (adsorbs) cations from the soil solution, holding nutrients that would otherwise leach...

Tools are now available to better define soils in terms of their productive capacity and for the routine seasonal monitoring of the water resource as it is captured and utilised by crops (or weeds if allowed)... Underpinning the push to improve water use efficiency is the need for farmers and their advisors to have a good understanding of how soils work in relation to water capture and storage and why some soils have the ability to hold more water for crop use than others... Rooting depth should be 101..

Cumulative soil water was calculated in vertical dipole (mm to 1.5 m) and horizontal dipole (mm to 0.75 m) or as a function of height-above-ground if the EM38 was raised above ground for readings... When we measure EC a across a paddock with variable soil texture, differentiating soil water content from other attributes becomes increasingly complex... For example, let us use the soil and calibration from Figure 2 (Black Vertosol from Pampas)...
