A nitrogen reference manual for the southern cropping region (Manual)

This Grains Research and Development Corporation (GRDC) manual provides current  knowledge about nitrogen management within cropping systems in the Southern region. It includes information on nitrogen cycles in agriculture, nitrogen fixing by legume crops, estimating nitrogen supplies from soils, crop yield potential and nitrogen demand, optimising economic and seasonal risks, and grower nitrogen strategy case studies. The manual recommends applying nitrogen fertiliser in-season based on available moisture and predicted yields to help ensure the nutrient demands of the crop can be fully met, while minimising the economic and seasonal risks of extra inputs, especially in wet conditions. While this manual was developed for the Southern region, it may relevant to other Australian cropping areas [PDF 8.2 MB, 104 pages]. #

Disclaimer:

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 Scientist 
Resource Suggestion
Step 1 of 3

We welcome your suggestions about valuable soil resources that could be included in the Smart Soils Resource Library. Please read this information before proceeding. Please remember, this Resource Library does not include scientific journal articles.

New resources are evaluated by Soil Science Australia’s membership of soil specialists.

Each new library resource is added after careful consideration, it must:
1. demonstrate good quality soil science. The resources must be scientifically valid. Case studies that contribute significantly to the understanding of soil management in Australian regions are also accepted.
2. be relevant to Australian soils, condition, constraints and management practices
3. add value to the Resource Library. If there are multiple resources in the Resource Library on the same topic then the suggested resource must improve on the existing resources that address the topic.
4. be readily available preferably in an electronic version. Some books may be out of print but should be available in libraries or from second-hand booksellers. The file size of resources should enable easy downloading or streaming.
5. be written in language appropriate for the intended audience.

Preferably, the resource should also meet the requirements of Web Content Accessibility Guidelines (WCAG) 2.1. to make web content more accessible and user friendly for everyone.
