Proximal sensing technologies on soils and plants on Eyre Peninsula locations
Aims

To develop predictive formulas that can be used by growers to estimate in-season soil moisture at different depths and crop nutrient content from proximal sensing (PS) data.

Key messages
  • Proximal sensing reflectance data predicts soil moisture with reasonable accuracy at depths (0-10, 10-30, 30-90 cm) on upper Eyre Peninsula in 2018.
  • Reflectance data may also be useful for predicting the amount of soil nitrogen and crop macronutrients, including but not limited to nitrogen, phosphorus, potassium and sulphur.
  • Further experimental data is required to use soil and crop reflectance as a means to predict nutrient content because environmental parameters can confound results.
