Fig. 5: Conceptual model illustrating shifts of soil health, microbial diversity, and crop yield under conservation agriculture response to warming.
From: Conservation agriculture improves soil health and sustains crop yields after long-term warming
Experimental warming triggered shifts in soil fungal richness and community composition and resulted in an improved soil health under conservation agriculture, including increased water infiltration and storage, carbon and nutrient cycling, and microbial activity. The improvement in soil health and shifts in soil fungal diversity contributed to higher crop yields under conservation agriculture. The up or down arrows showed increased or decreased soil health indicators response to warming under conservation agriculture. The linear trends indicated warming effects on crop yields and soil health indicators over time under conservation agriculture.
