Water use efficiency is a key driver to optimizing yields and being sustainable in lower rainfall districts. Crops need to be able to access the sub-soil to make full use of the soil moisture available throughout the soil’s profile. Sub-soil constraints are possibly the greatest limiting factor to water use efficiency.
Soil acidification is recognized as a major soil constraint that is threatening both agricultural economic and natural resource throughout the productive agriculture areas of Western Australia. It is one of the few soil constraints that can be treated but questions remain such as:
- What is the best incorporation method (if at all)?
- How long will the benefits last and is it economical?
