Fertigation is being increasingly adopted by citrus producers as an alternative to traditional approaches to supplying fertilisers to trees.

Managing fertigation systems to achieve good productivity and avoiding fertiliser wastage and loss.

This case study looks at prototyping the automated soil solution sampling and measurement tool to locate salt in the soil profile.

* Determine/update the crop salinity relationships * Determine the variability of EC (soil water) and leaching efficiency in the field * Simulate different scenarios of River Murray salinity at Morgan * Input to the M

Soils that disperse tend to have poor drainage; excessive swelling closes soil pores, which also block up with dispersed clay, sand and silt.
