Organic nitrogen management is particularly challenging because nitrogen from organic sources such as compost, soil organic matter, cover crops, crop residues, and soil amendments must be converted by microbes to a plant-available form. Matching plant-available nitrogen to crop demand is necessary in order to provide sufficient nitrogen for optimal yields, while reducing the risk of environmental pollution. Furthermore, nitrogen-reporting requirements call for information on plant-available nitrogen, as opposed to total nitrogen applied. As a group, we will complete a comprehensive nitrogen budget, through which you will be given guidelines and calculations for estimating plant-available N. This will be directly translatable for use with your own compost, soil report results, amendments, etc.
