Wheat and Lupin Potassium Responses

Assessment of soil test and K responses for wheat and canola in southern Victoria.

IPNI-2013-AUS-18

The Better Fertilizer Decisions for Crops Project (BFDC) that concluded in 2012 identified several gaps in data around the development of robust soil test calibrations. This project seeks to collect crop responses to applied potassium particularly from the high rainfall zone of southeastern Australia. Read more

Do we need to revisit potassium?

Interpretive Summary

2014

There is almost no data available on crop responses to applied K in the southern grains region, especially the high rainfall zones where cropping is becoming more intensively practiced. A single field trial experiment was established at Lake Bolac, Victoria in 2013 to investigate the response of wheat and lupins to applied K. The site selected was on a yellow Kurasol near Lake Bolac in western Victoria.

2013

The Better Fertilizer Decisions for Crops project identified gaps in the dataset for wheat and canola responses to K in eastern Australia. This project will support additional soil measurements of selected K fertilizer application rate experiments in southwestern Victoria, undertaken by the New South Wales Department of Primary Industries.
