Nutrient Characterization in Soil Aggregate Fractions with Different Fertilizer Treatments in Greenhouse Vegetable Cultivation

Fertilization affects the formation and stability of soil aggregate, as well nutrient status aggregate. However, potential effect compost on aggregate its characteristics is still unclear. In view this, we conducted a greenhouse vegetable cultivation experiment to evaluate water-stable (WSA) indices stoichiometry at 0 20 cm depth with four treatments: (1) no fertilizer (CK), (2) chemical (CF), (3) organic (OF), (4) plus (CO). The results showed that proportion 2 0.25 mm fraction was greatest, followed by 0.053 mm, which accounted for 41.83 49.53% 28.60 31.88% weight, respectively. mean weight diameter (MWD) value >0.25 in CF, OF, CO treatments were significantly higher than CK treatment. Within fertilization treatments, MWD those CF OF. Among all aggregates, carbon (SOC), total nitrogen (TN), phosphorus (TP) contents highest mm. increased SOC, TN, TP compared SOC content fractions >2 treatment OF TN aggregates (except < mm) components contributed greatly reserves. There noticeable difference between different treatments. Redundancy analysis (RDA) revealed physicochemical factors, including TP, pH, explained To summarize, combined positively affected accumulation dryland.
