Although microbial decomposition of plant litter plays a crucial role in nutrient cycling and soil fertility, we know less about likely links specific traits decomposition, especially relation to climate change. We study here wheat straw under ambient manipulated conditions simulating future scenario (next 80 years) agroecosystems, including decay rates, macronutrient dynamics, enzyme activity, communities. show that will accelerate rates only during the early phase process. Additionally, projected change increase relative abundance saprotrophic fungi decomposing straw. Moreover, impact on community assembly molecular ecological networks both bacteria strongly depend phase. During stochastic processes dominated conditions, whereas deterministic highly bacterial fungal communities simulated conditions. In later phase, similar shaped scenarios. Furthermore, over phases enhanced complexity interaction networks. concluded rate associated like inter-community interactions is restricted decomposition.
