Substituting chemical fertilizers with biogas digestate can mitigate the negative impacts of fertilizers on soil quality to promote the recycling of livestock manure. This study aims to evaluate the effects of chicken manure biogas digestate as a replacement for chemical fertilizers in rice cultivation, assessing soil nutrients dynamics, bacterial communities, nitrogen (N) metabolism enzyme activity, and rice growth.
