    Throughout NA, rules governing the application of digestate, or any organic material/waste, to ag lands are set by the state/province, depending on the classification. These rules are set with an understanding of nutrient mobility, plant utilization, pH loading, etc., usually accompanied with a soil sampling program to monitor past applications and to plan future applications. Generally, there is not additional value placed on digestate over other ag source materials such as manure, with the benefits being the nutrient content, organic matter, and in some regions the water within the liquid phase is used to offset irrigation water needs.
