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..

The percentage of growers using some no-till reflected in the figures may not reflect the percentage of no-till adoption observed at the time... Overall, a vast majority of growers also expected the no-till systems to result in less soil erosion... While users and non-users generally did not have differences in beliefs about the likelihood of herbicide resistance or higher herbicide costs, overall, it was more common for no-till users to expect less weed emergence under no-till with stubble retention systems...

The protocol consists of ten sections, intended to provide guidance for the standard measurement, recording and interpretation of soil conductivity data; particularly for third parties that might receive the data for subsequent analyses and development of recommendations... Some contractors provide both data sets at no extra cost... Each person in the soil conductivity mapping services industry shall have full regard for achieving excellence in the practice of the surveying and interpretation and of maintaining the highest standards of ethical conduct in responsibilities and work for an em...

The trend for increasing herbicide resistance in Australian cropping systems is likely to continue, at least in the near future... The majority of plants in a wild weed population will be susceptible to herbicides effective on that species...
