responsive soil

Catalogue: GRDC Research Summaries
Finding the pieces that maximise water use efficiency.. The variation within the strips can be used to tease out soils that are more or less responsive to ameliorative treatments... There are also opportunities to develop other products from the soils and geophysics data sets that will help farmers increase their water use efficiency through improved recognition and remediation of constraints...

Deep ripping not appropriate for all soil types A comprehensive understanding of the cause and location of high soil strength is required before undertaking deep ripping as research has shown it is does not provide an economic solution in some soil types... KEY POINTS Deep ripping of compacted soils is most likely to improve grain yields on sandy soils and where compaction has occurred on upper parts of the soil profile through machinery traffic or livestock trampling... Overall, compacted subsoils impede root growth, causing reduced plant vigour and poorer water-use efficiency as roots have limited access to water and nutrients, especially in the subsoil...

Gypsum applied to responsive soils along Western Australia's south coast has improved water use efficiency (WUE) - the amount of grain produced from a given amount of rainfall... With results restricted to certain soils, growers will need to test their soil to determine whether it is responsive to gypsum... Gypsum counteracts sodic soils by reducing clay dispersion, which improves soil structure and drainage and reduces waterlogging...

Fertiliser nitrogen can be applied at any time of the year according to the season's progress and budget... Some paddocks or soil types may respond in some years and not in others due to species and cultivar, time of seeding (both mineralisation and root system expansion) or soil moisture/rainfall... Overall, the message is: do not overcomplicate the fertiliser program...
