Studies

This informational studies page delves into the fascinating world of no-till and zero-till farming systems, showcasing a variety of case studies and research findings. Explore this information to learn more about the research and data behind these systems and how they are transforming the way we approach modern agriculture.

Long Term No-Till Trial Delivers Data Legacy

The Western Australian No-Tillage Farmers Association (WANTFA) long-term field trial, which ran from 2006 to 2019, was designed to test and further develop high-quality no-till systems based on the conservation agricultural principles of permanent soil cover, minimal soil disturbance and diverse crop rotations.

Long-Term Economic Impacts of No-Till Adoption

No-till has long been considered a sustainable agricultural practice because of its potential to provide on-farm productivity benefits as well as off-site environmental benefits. However, “economic concerns” have been identified as one of the largest barriers to adopting no-till (i.e., costs associated with adoption possibly being greater than the returns in the short term). This study evaluates the long-term economic impact of no-till adoption using rich plot-level data from a long-term field experiment over the period 1996–2019.

Soil Security: Dec 2023

"Our results reveal that continuous no-till adoption generates positive economic benefits by reducing overall input costs. Moreover, the profitability of no-till increases as one continuously uses this practice over an extended period of time. Furthermore, because continuous no-till can be both economically and environmentally attractive, our results are consistent with recommendations to support long-term adoption of continuous no-till management."

Risk & Reward - Early Sown Canola

Dylan and his family farm 5800 hectares near Latham in WA’s northeastern wheatbelt. The family farming enterprise was previously a cereal dominated system; however, over the past 12 years the Hirschs have added and increased their canola program, with 50 per cent of it going to canola in 2021.

GRDC Case Study: 16th Jan 2024

The Hirschs' of Latham, have also developed the confidence to sow canola earlier and earlier; they now have everything ready to go by 20 March in case an opportunity arises. In the past three years, they have had canola in the ground in March and have had pleasing results more often than not.

zero-till cropping and added manure

A conservative zero-till cropping strategy with added manure and high nitrogen applications has proven to be the best-performing system to maximise returns in Central Queensland.

GRDC Study: 22nd March 2024

GRDC’s Northern Farming Systems project has been experimenting with different systems for nearly a decade. The Northern Farming Systems project concentrates on how farming systems’ modifications affect water use efficiency, nutrient balance and nutrient use efficiency, changes in pathogen and weed populations, changes in soil health, and profitability.

Case Studies - Spring/Summer sown crops

The 2021 season was subject to extreme waterlogging, resulting from above-average 2020-21 summer rainfall followed by consistent rain in autumn 2021. This resulted in a significant yield penalty and, in places, total crop loss. In some areas, paddocks were too wet for machinery and sowing of the winter crop was not possible.

GRDC Study: 2021

This project, with GRDC investment, aimed to provide this information and increase grower awareness of spring and summer cropping options available to them and how they would perform within their region after a waterlogged growing season.
