In this GRDC video, Lori Phillips explains why focusing on nitrogen inputs in agricultural systems is important for productivity and commercial viability. She discusses how the complex community of soil microbes transforms nitrogen into compounds that may or may not be beneficial for agriculture. The video also explores how you can improve your nitrogen use efficiency to improve the uptake of nitrogen in plants. Researchers are using both chemical and biological analyses to determine how different management practices impact specific microbial communities. For instance, how you encourage microbes that convert ammonia into nitrates. It can be fairly simple to tweak the soil biology system with common agricultural practices such as disturbance, timing of fertiliser application and depth of fertiliser placement. While this video was produced for Victoria, it is relevant for other agricultural regions [6:46].#
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.

SSA reminds users that these resources are a guide only. Our understanding of soil science is improving continuously so it is important to check the suitability of the information for your purpose with an appropriately qualified professional such as a Registered Soil Professional or a Certified Professional Soil ScientistÂ
