Anaerobic digestion is a process that utilizes microorganisms to convert biomass into methane gas combined with a nutrient rich waste product - this product is known as digestate. The digestate from this conversion can be used to fertilize plant material and, as a result, reduce the use of inorganic, synthetically produced fertilizers. The use of organic fertilizers, such as those produced from anaerobic digestion, are less prone to leaching and burning of the target plants as opposed to inorganic fertilizers. Additionally, the use of organic fertilizers may help improve soil health by improving soil structure and increasing microbial activity, and provides longer lasting nutrition for the plants as most of the available nitrogen is released over time rather than all at once. However, it is unknown if there are any adverse effects of the waste products produced by digestion on the plants. Additionally, the ideal form of the product and rates of application are unknown at this time.

厌氧消化是一种利用微生物将生物质转化为甲烷气体的过程，以及一种营养丰富的废物产品-这种产品被称为沼气。这种转化产生的沼气可以用来给植物材料施肥，结果是减少了无机合成肥料的使用。与使用无机肥料相比，使用有机肥料，如从厌氧消化产生的有机肥，不太容易对目标植物进行淋溶和焚烧。此外，使用有机肥料可能通过改善土壤结构和增加微生物活动来帮助改善土壤健康，并为植物提供更持久的营养，因为大多数有效氮是随着时间的推移而释放的，而不是一次性释放出来的。然而，尚不清楚消化产生的废物是否会对植物产生任何不利影响。此外，目前尚不清楚该产品的理想形式和使用率。
