Current Projects

The Liebe Group is committed to giving back to growers through local research and development. Each year the group conducts multiple projects, encompassing grower needs and industry expectation for improved production.

Currently the Liebe Group is involved in the following projects:

Subsoil Constraints – Understanding and Management

It is estimated that more than 14.25 million hectares in the Western Australian Wheatbelt is acidic or at risk to become acidic (Gazey et al, 2014) making acidity one of the major limiting production factors to modern day farming systems. This is estimated to cost the agricultural industry $498 million per annum equating to 9% of WA’s annual crop (Herbert, 2009). This project aims to determine which ameliorant practice is the most effective and economic in remediating subsoil acidity at depth.

Best management of ameliorated non-wetting soils for the Geraldton Port Zone

Soil water repellence was ranked the most important soil constraint on their properties by growers during a 2010-2011 Keepad survey conducted by Steve Davies from DAFWA. With the adoption of tillage practices such mouldboard ploughing and spading, this project aims to look t the best way to apply nutrients on non-wetting soils after amelioration in the Geraldton port zone.

Understanding the implications of rotations in a low rainfall zone (Practice for Profit)

This project aims to examine the difference in profitability between low and high input cropping practices over an extended period of time. The trial has been running since 2011 and is now entering it’s seventh consecutive season at the Monk’s Road site, east of Dalwallinu.

Implementing change and innovation through a farmer-based Mentoring Program

Agriculture is highly diverse in nature, and as a result, there is a wealth of knowledge and experience within regional communities. This project will engage those farmers who are willing to offer their support and advise to innovative young growers. It aims to build the capacity of farmers in the region and improve sustainability through on farm changes made during the project.

Innovative lime incorporation at west Wubin

This project investigates the capacity of a recently released disc plough to incorporate lime, combating subsoil acidity and, to quantify the following seasons’ soil/crop responsiveness to the deep lime incorporation using soil and tissue analysis, plant growth assessments, and yield.

Utilising precision agriculture technologies to manage climate variability and improve nutrient use efficiency

The advancement of precision agriculture (PA) has enabled the accessibility of affordable technologies that can be implemented on-farm to improve sustainable cropping practices. This project will investigate the environmental, agronomic and economic benefits of Variable Rate Technology (VRT). This project will address the NRM value of nutrient management and soil health by flexibly applying suitable nutrient rates for varying soil types, minimising excess build-up of unused fertilisers and chemicals.

Working together to deliver multiple benefit messages to growers through a whole systems approach to soil management

This projects researches the most appropriate liming strategy to maximise return on investment and increase knowledge around the economics of different soil pH management, products and techniques utilising the Lime Economic Calculator.

Sowing the seed with youth today

The Liebe Group’s members expressed their desire for the Liebe Group to get actively involved with the Dalwallinu District High School in an effort to encourage students and engage them in agriculture. As a result of this the Liebe Group and Dalwallinu District High school are working together to bring agriculture into the classroom. The program aims to raise the profile of modern agricultural practices with students in a rural setting while encouraging students to explore and consider the opportunities for employment within the sector.
