abstract = {Soil water status, which refers to the wetness or dryness
of soils, is crucial for the productivity of agroecosystems,
as it determines nutrient cycling and uptake physically via
transport, biologically via the moisture-dependent activity
of soil flora, fauna, and plants, and chemically via
specific hydrolyses and redox reactions. Here, we focus on
the dynamics of nitrogen (N), phosphorus (P), and sulfur (S)
and review how soil water is coupled to the cycling of these
elements and related stoichiometric controls across
different scales within agroecosystems. These scales span
processes at the molecular level, where nutrients and water
are consumed, to processes in the soil pore system, within a
soil profile and across the landscape. We highlight that
with increasing mobility of the nutrients in water,
water-based nutrient flux may alleviate or even exacerbate
imbalances in nutrient supply within soils, for example, by
transport of mobile nutrients towards previously depleted
microsites (alleviating imbalances), or by selective loss of
mobile nutrients from microsites (increasing imbalances).
These imbalances can be modulated by biological activity,
especially by fungal hyphae and roots, which contribute to
nutrient redistribution within soils, and which are
themselves dependent on specific, optimal water
availability. At larger scales, such small-scale effects
converge with nutrient inputs from atmospheric (wet
deposition) or nonlocal sources and with nutrient losses
from the soil system towards aquifers. Hence, water acts as
a major control in nutrient cycling across scales in
agroecosystems and may either exacerbate or remove spatial
disparities in the availability of the individual nutrients
(N, P, S) required for biological activity.},
