Researcher Matt Newell (New South Wales Department of Primary Industries, Cowra Agricultural Research and Advisory Station) also wrote the following brief detailing highlights of his recent visit to the Land Institute:

Perennial Grains Activity in Australia

Developing perennial grains offers a novel approach to sustainable agricultural production while maintaining food security. In Australia, research has highlighted the need to return perennials back into the landscape to ameliorate the soil degradation caused by annual cropping. A component of this research, conducted by a team led by NSW DPI, successfully demonstrated the feasibility of perennial grains for Australia. Recent interest in developing cropping systems for the permanent pasture zone in Australia, has indicated the need to develop dual purpose perennial grain crops which could supply a forage source for grazing animals as well as harvestable grain, improving the profitability in a mixed farming enterprise. Perennial grains could offer solutions to the impediments to annual grain production in this zone as well as limit the potential environmental damaged caused through the removal of perennial species.

Recently Matthew Newell from NSW DPI travelled to The Land Institute in Kansas. This provided an opportunity to work more closely with colleagues there, allowing a better understanding of the breath of research undertaken. During this time new crosses with wheat and other perennial grasses, including some Australian native grasses were developed. This is important as by studying these crosses we can learn more about the genetics of the perennial habit. Also it provides an avenue to increase the diversity among perennial cereals currently available, with an aim of creating material that may demonstrate improved adaptability to differing environments.

Further studies were completed in investigating biological nitrogen (N) fixation in perennial sorghum and the ability of perennial sunflowers to extract deep soil N. The importance of these experiments is that it provides information on the nitrogen economy in perennial cropping systems. In modern annual cropping systems there is high dependence on synthetic nitrogen inputs which require a considerable amount of energy to produce. Recovery of added synthetic nitrogen in grain farming is at best 50% which leaves a large amount of nutrient that is susceptible to loss with potential to cause environmental damage. By comparison, in a farming system based on perennials, nutrient loss is reduced due to the greater soil volume accessed by roots and better synchrony between crop demand and nutrient availability.

It is hoped that this activity will be beneficial in sourcing funds from both Australian and USA donors to support an international project between TLI and DPI to further perennial grains research.

Third Annual Perennial Grain Research Reporting Session in Manitoba, Canada

July 16-17, 2012

The first day consisted of ten research talks from five research institutions, ranging from plant molecular genetics to ecosystem services to pathology to food science. The second day consisted of a field tour of long-term cropping system research trials and perennial grain breeding plots, including intermediate wheatgrass, perennial rye, perennial sunflower and perennial wheat. Make sure to check out the agenda and the presentations from sessions.

Research scientists shared results from ongoing and recently completed projects
and discussed future directions of their work. Thanks to Doug Cattani and his team
and to Manitoba Agriculture, Food and Rural Initiatives for making this meeting

The session also included a tour of the facilities. Take a glance at the perennial grain in Manitoba.

Summary of the KBS Perennial Wheat and Grains Field Day!

KBS Perennial Wheat and Grains Field Day
Wednesday, June 27, 2012  

We had a great turnout at the Perennial Wheat and Grains Field Day! Take a look at our Perennial Wheat and Grain Field Day Agenda to see what we did throughout the day.

Our hardworking grad students Sienna Tinsley, Christine Sprunger and Nikhil Jaikumar were able to present their preliminary data and results they have collected regarding perennial grains to the group. Throughout the field day, farmers were encouraged to interact with the grad students to learn more and ask questions regarding the growing promise of perennial grains. With this, the farmers were able to evaluate the potential crops for their needs.  Though we haven’t reached our goals with perennial grains yet, we were able to leran more about about the research that’s being done and discuss potential outcomes for such crops.
