Proximal sensing technologies on soils and plants on Eyre Peninsula locations

Aims

This research was done to develop predictive formulas that can be used by growers to estimate in-season soil nutrients from soil samples taken at different depths and crop nutrient content from proximal sensing (PS) data.

Key messages

Proximal sensing reflectance data predicts soil moisture with reasonable accuracy from samples taken at depths (0-10, 10-30, 30-60, 60-100 cm) across 46 Eyre Peninsula locations.
Moderate relationships were found between % organic carbon, pH(water) and soil spectral data.
Reflectance data have been proven useful for predicting the amount of crop macronutrients, including nitrogen, phosphorus, potassium and sulphur.
Further experimental data is required to test the reliability of the existing predictive models of soil absorbance and crop reflectance as a means to predict nutrient content.
