Nitrogen cycling inputs and losses: towards a deeper understanding: GRDC (Webpage)
This Grains Research and Development Corporation (GRDC) webpage explains how nitrogen is vital for crop production but is easily lost through leaching, volatilisation and denitrification. It shows how nitrogen moves through soil, plants and the atmosphere, and how losses occur through microbially driven processes. It discusses natural and fertiliser-based nitrogen inputs, the importance of timing applications to crop demand, and how different farming practices affect nitrogen efficiency. Managing nitrogen better supports productivity and helps reduce greenhouse gas emissions and water pollution. Understanding the full nitrogen cycle is essential for improving fertiliser use and long-term soil quality.#
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
