Sowing rate and nitrogen management in cereals for increasing ground cover on sandy soils – VIC (Case study)
This case study from the Mallee Catchment Management Authority (CMA) examines how sowing rate and nitrogen (N) fertiliser interact to influence crop yield and profitability in low rainfall, sandy soil Mallee farming systems in Victoria. The findings, from the field study in Kooloonong, suggest that sowing rate and N management had little effect on cereal biomass production or ground cover. Instead, landform variation (such as dunes and swales) was the key driver of crop performance and wind erosion risk. The authors conclude that site-specific management is likely to deliver better outcomes than uniform approaches [PDF 1.5 MB, 8 pages]. While this study focused on Victorian mallee farming systems, it would also be relevant to other southern Australian low rainfall regions with sandy soils.#
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.
