abstract = {BackgroundColloid-facilitated phosphorus (P) transport is
recognized as an important pathway for the loss of soil P in
agricultural systems; however, information regarding soil
aggregate-associated colloidal P (Pcoll) is lacking. To
elucidate the effects of aggregate size on the potential
loss of Pcoll in agricultural systems, soils (0–20 cm
depth) from six land-use types were sampled in the Zhejiang
Province in the Yangtze River Delta region, China. The
aggregate size fractions (2–8 mm, 0.26–2 mm,
0.053–0.26 mm and < 0.053 mm) were separated using the
wet sieving method. Colloidal P and other soil parameters in
aggregates were analyzed.ResultsOur study demonstrated that
0.26–2 mm small macroaggregates had the highest total P
(TP) content. In acidic soils, the highest Pcoll content was
observed in the 0.26- to 2-mm-sized aggregates, while the
lowest was reported in the < 0.053 mm
(silt + clay)-sized particles, the opposite of that
revealed in alkaline and neutral soils. Paddy soils
contained less Pcoll than other land-use types. The
proportion of Pcoll in total dissolved P (TDP) was dominated
by < 0.053 mm (silt + clay)-sized particles.
Aggregate size strongly influenced the loss potential of
Pcoll in paddy soils, where Pcoll contributed up to $83\%$
TDP in the silt + clay-sized particles. The Pcoll
content was positively correlated with TP, Al, Fe, and the
mean weight diameter. Aggregate-associated total carbon
(TC), total nitrogen (TN), C/P, and C/N had significant
negative effects on the contribution of Pcoll to potential
soil P loss. The Pcoll content of the aggregates was
controlled by the aggregate-associated TP and Al content, as
well as the soil pH value. The potential loss of Pcoll from
aggregates was controlled by its organic matter
content.ConclusionWe concluded that management practices
that increase soil aggregate stability or its organic carbon
content will limit Pcoll loss in agricultural systems.},
