Summary

Perennial production systems offer many advantages for maintaining ecosystem functions, both above and below-ground.

This page will help you:

understand the benefits of perennial cropping systems
access perennial cropping resources generated in collaboration with DEW and the Future Farm Industries CRC.

Perennial cropping system benefits

Perennials maintain the soil cover, soil structure and biota and have deeper root systems than annuals and thus provide soil stability and enhanced soil health. They can also tap available soil nutrients, enhance biodiversity, make more water available to plants, and capture and sequester carbon to a greater extent than more shallow rooted annual plants.

These deeper roots allow perennials to access water stored deeper in the soil profile which enables them to grow and maintain ground cover during the drier periods of the year. Their deep and extensive root systems are also effective in reducing the impact of salinity by lowering the water table and preventing soil erosion by binding soil.

These systems help to reduce salinity and soil erosion, conserve biodiversity and contribute to drought and climate change adaptation.

Future Farm Industries CRC project

In recent years, DEW partnered with the Future Farm Industries CRC, which aimed to increase the adoption of sustainable and profitable farming systems based on perennial plants.

Although the Future Farm Industries CRC has now concluded, a wealth of information was produced by DEW and other research partners on woody crop species and industries (FloraSearch project), carbon accounting methodologies and a better understanding of the growth, productivity and carbon sequestration potential of revegetation and farm forestry in southern Australia (Carbon Sequestration from Revegetation project).

Archived information from the Future Farm Industries CRC provides a valuable resource for perennial production systems.
