To demonstrate the use of soil mapping and soil moisture sensors as data sources for variable rate irrigation and fertigation decisions, with the ultimate aim of reducing pumping and fertiliser costs, improving potato yields and quality and reducing the risk of nutrient enrichment of waterways and wetlands.
Key messages
Centre pivot irrigation plots were surveyed using gamma radiometric and electromagnetic sensors.
Soil moisture sensors with 3G logging devices were installed in contrasting soil types according to interpretation of the gamma radiometric data.
Replicated yield and quality estimates were conducted on each soil type
Yields and tuber classes varied significantly between soil types
Experiments to determine optimal irrigation and fertiliser regimes for contrasting soil types will be conducted in 2017.
