Optimising yield with variable rate fertiliser inputs: Lameroo – SA (Case study)
This case study from Mallee Sustainable Farming describes a trial conducted on a cropping property in southern South Australia in an area showing variability in crop responses to nitrogen and phosphorus. The grower selected a paddock and used publicly available satellite and NDVI data to map the soil types in the paddock. This information guided the choice of soil sampling sites. Variable rate technology (VRT) was used to selectively apply nitrogen and phosphorus for a wheat crop. Profitable increases in wheat grain yield were obtained in certain paddock zones. This study indicates that this approach can provide significant benefits. While the content focuses on South Australia, the information is applicable to other Australian regions [PDF 3.8 MB, 4 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.
