This factsheet explores asparagus root growth patterns.

Research over the past 20 years has shown that root damage associated with annual re-ridging has a major impact on asparagus plantation longevity and productivity.

Such root damage increases susceptibility to crown and root rot infection and/or disease (caused by Phytophthora asparagi and Fusarium species), which contribute significantly to yield decline.

Long-term asparagus field trials were established in April 2016 (AHDB Horticulture project FV 450) to develop and evaluate ‘Best Management Practices’ (BMPs) that could prevent and/or remediate wheeling compaction, improve soil structural status and reduce run-off and erosion in asparagus production systems.

A video guide is created to sample your asparagus crops to better understand your soil. Samples received by Cranfield University will create a national database of soil profiles and offer growers a personalised root map to inform re-seeding.
