Understanding and managing spatial variation in stored soil moisture for better crop management decisions locations
Aims

To (i) improve the understanding of how soil moisture probes and Yield Prophet can be used to complement each other; (ii) increase the range of APSoil soil type selections in Yield Prophet by modifying existing soil types based on the probe data; (iii) provide growers with access to real-time soil moisture data and periodic Yield Prophet reports from soil types and cropping scenarios that are representative of their area; and (iv) cross-validate soil moisture probe data with Yield Prophet soil moisture modelling.

Key messages

A network of soil moisture probes and Yield Prophet sites has been established across the Esperance, Albany, Kwinana East and Kwinana West port zones with the aim of providing public access to real-time soil moisture and weather data and periodic Yield Prophet reports to aid in-crop decision making, with particular reference to top-up nitrogen decisions.

Growers and agronomists have commented that the sites provided useful supporting information when making top-up nitrogen decisions, with the soil moisture probes providing additional confidence in the model’s output. Continuation of the Yield Prophet sites and soil moisture data recording and analysis will continue in 2015 across the Esperance/Albany and Kwinana East port zones, with the aim of further refining the sites to improve their accuracy and providing access to Yield Prophet and soil moisture information in a more user-friendly format.
