The coupled nonlinear dynamics of biotic and abiotic processes in ecohydrological systems give rise to complex system with several nonlinearities and feedbacks whose understanding will help us to sustainably use soil and water resources and maintain valuable ecosystem services. With this background, we discuss how soil moisture dynamics controls the cycling of soil nutrients (nitrogen and phosphorous in particular) at different time scales, driving the competition for mineral nutrients between microbial biomass and plants.
