BACKGROUND
KI experiences waterlogging in winter months, so broad beans have become a common crop on the island in recent years as they are tolerant of waterlogging conditions. However in low pH soil conditions, poor nodulation can cause low yields.
As an agronomist, Ms Stanton noticed that canola after lupins were yielding higher than canola after beans.

Agiculture Kangaroo Island: Jenny Stanton
The problem
Different legume crops appeared to be fixing different amounts of nitrogen on Kangaroo Island.
The research
The trial is examining how much N lupins are fixing, compared to beans and subclover.
Research aims
The project will target the following questions:
In the field
Varieties in the trial include Coogee peas, Samira faba beans, Jenabillup lupins, Monti and Gosse sub clover.
