Ripping technology: Technology considerations for cost-effective subsoil loosening (Factsheet)
This Grains Research and Development Corporation (GRDC) factsheet (published 2022, updated 2025) outlines four operational challenges faced by growers using deep ripping. These include excessive seed depth caused by furrow slumping, soil throw from rear tynes into the furrows created by front tynes, crop damage from pre-emergent herbicides mixed through displaced topsoil, and increased risk of soil erosion. The factsheet summarises practical solutions trialled by growers, such as rolling after ripping, adjusting or reducing pre-emergent herbicide use, sowing early in warm conditions to promote rapid emergence and reduce erosion risk, modifying tyne configuration, and other machinery adjustments [PDF 903 KB, 6 pages].#
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.
