Title:
Core Soil Extracellular Enzymes for Sustainable Biomass Production with Perennial Crops (CoreEEs)

Research area and project description:
Denmark has an ambition of carbon (C) neutrality by 2050. The greenhouse gas (GHG) emission from Danish agriculture exceeds 30% of total national emissions in 2018. To realize C neutrality, there is a high potential to reduce GHG emissions from agriculture through optimized cropping systems and managements. Meanwhile, human demands for agricultural products are growing substantially due to the rapid increases of using biomass yield for biorefinery. Thus, sustainable agroecosystems should reduce GHG emissions without compromising food security and biomass use for biorefinery. Emerging studies provide some of the most groundbreaking ideas that harnessing soil microorganisms for sustainable biomass yield offers one of few untapped reservoirs to agriculture green transition. In this proposal, we will use multiple advanced methods to explore the core microbial processes for high biomass yield and low GHG emissions with perennial crops. Our results will inform the optimized cropping managements through novel microbial perspectives.

Maximizing microbial functions for sustainable biomass yield is a promising technology for agriculture green transition. Despite the large potential, it is challenging to precisely manage the species-rich soil microbes. Soil extracellular enzymes are produced by the plant and microbial assemblages to catalyze the degradation of organic matter, providing novel insights to understand the complex plant-microbial feedbacks. This project will investigate the interactive effects of perennial crops and fertilization strategies on C-, nitrogen- and phosphorus-acquiring extracellular enzyme activities and their relationships with biomass yield and GHG emissions. Our objectives are to identify and manage core enzymes for higher biomass yield and lower GHG emissions. Finally, the current perennial systems and fertilization strategies will be optimized through the novel enzymatic indicators to better serve the agriculture green transition.

The overarching purpose is to maximize the microbial functions for agriculture green transition. The relationships between microbial C use efficiency and enzymatic stoichiometry will be explicitly evaluated with perennial crops under different fertilization strategies. To meet plant nutrient requirements, we will develop the novel enzymatic indicators for precise fertilization. We will likely apply the optimized fertilization strategies in broad areas by considering the specific climatic, environmental and edaphic variables. To serve agriculture green transition, we will identify and harness a range of plant-growth-promoting enzymes, which will likely be managed for eco-enzyme fertilizers. In this project, we will likely provide novel enzymatic proxies to advance the understanding of the intricate plant-microbial feedbacks.
