Popis: | Soil nutrients contribute to ecosystem-level processes and are important for productivity, community structure, and fertility in terrestrial ecosystems. Crude oil–stressed agricultural soil was subjected to phytoremediation for 12 weeks, and the nutrient status thereafter was characterized to investigate the inherent effects on such soils in relation to nutrient mineralization and community shifts. Manure additions significantly increased Mg, Na, NO3-N, PO4 −, and SO4 2− contents along with pH values. Accumulated biomass and leaf area measurements were used to monitor nutrient cycles upon amendment addition. Experimental results indicate that after 90 days, the biotreatment had significantly higher levels of monitored nutrients (above 2500 mg/kg NO3-N) than the unplanted control ( |
