Understanding phosphorus availability in soils and its effect on plant root structure – SA, QLD (Factsheet)
This Grains Research and Development Corporation (GRDC) factsheet explains how phosphorus behaves in Australian soils and how soil properties influence its availability to crops. It emphasises that fertiliser efficiency depends on interactions between soil type, fertiliser formulation and where phosphorus is placed in the soil relative to crop roots. The factsheet summarises research that examined how different phosphorus fertilisers and placement depths affect the distribution of plant-available phosphorus and crop root growth. The work showed that fertiliser choice and depth of placement can strongly influence root development, and that the movement and availability of phosphorus in soil varies with soil type. While the research was conducted in South Australia and Queensland, the findings are relevant to other Australian grain-growing regions [PDF 494 KB, 3 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.
