Soil inversion by ploughing: technology considerations for inversion ploughing of sandy soils – Southern and Western regions (Factsheet)
This Grains Research and Development Corporation (GRDC) factsheet describes soil inversion by ploughing as a strategic soil amelioration practice for managing multiple surface soil constraints. It explains how mouldboard and one-way ploughs fully invert the soil profile to bury water-repellent topsoil, weed seeds, herbicide residues and disease inoculum while bringing less constrained soil to the surface. The factsheet outlines where soil inversion is most effective, particularly on sandy soils with severe water repellence, high weed seedbanks or surface acidity, and highlights the importance of correct depth, soil condition and machinery setup. It also discusses risks such as erosion, nutrient stratification and organic matter loss, and emphasises the need for careful paddock selection and post-plough management. While the information focuses on Australian broadacre cropping systems, the principles are relevant to other regions with similar sandy soils and soil constraints [PDF 2.6 MB, 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.
