“…Agricultural application of sewage sludge is an effective waste disposal and soil amendment technique that can improve the chemical, physical, and biological characteristics of soils [16][17][18][19]. Sewage sludge is rich in organic matter and other nutrients and can be used for mudflat salt-soil amendment [9,20,21].…”

“…However, the application of sewage sludge combined with green manuring to amend mudflat salt-soils has received no attention. The impacts of applying sewage sludge alone to reclaimed mudflat soil on fertility development, growth of ryegrass, Sesbania, and maize and on heavy metals behaviors including their accumulation and fraction in soil and uptake by plants were investigated and evaluated in our previous studies [9,20,21,35]. This study was one of pioneering studies to investigate and evaluate the sustaining effects of sewage sludge amendment combined with green manuring on the soil aggregates, organic carbon, salinity, pH, and N and P of mudflat salt-soil, as well as yield of maize (Zea mays L.) in mudflats salt-soil in a rain-fed agroecosystem.…”

Sewage sludge and green manure have become widely used organic amendments to croplands in many regions of the world. However, the amending effect of the combination of sewage sludge with green manuring in reclaimed coastal mudflat salt-soil has been unclear yet. This paper was one of earlier studies to investigate and evaluate the effects of sewage sludge amendment combined with green manuring on selected soil physicochemical properties of the mudflat soil in a rain-fed agroecosystem. The mudflat salt-soil was amended by one-time input of sewage sludge at the rates of 0, 30, 75, 150, and 300 t ha −1 . After green manuring for three consecutive seasons, maize (Zea mays L.) was planted in 2013 and 2014. The results showed that SSA combined with green manuring decreased bulk density, pH, salinity, and exchangeable sodium percentage of the topsoil (0-20 cm soil layer) and increased aggregate stability, cation exchange capacity, and N and P concentration of the topsoil. As a result, the maize yield increased with the increase of SSA rates. Sewage sludge combined with green manuring can be applied in coastal mudflat salt-soil amendment, which provides an innovative way to create arable land resources and safe disposal of sewage sludge.

The total environment includes 5 closely-linking circles, in which biosphere and lithosphere are the active core. As global population increases and urbanization process accelerates, arable land is gradually decreasing under global climate change and the pressure of various types of environmental pollution. This case is especially for China. Land is the most important resources for human beings' survival. How to increase and manage arable land is the key for sustainable agriculture development. China has extensive marshy land that can be reclamated for the better potential land resources under the pre-condition of protecting the environment, which will be a good way for enlarging globally and managing arable land. Related studies have been conducted in China for the past 30 years and now many results with obvious practical efficiency have been obtained. For summarizing these results, salt-soil will be the main target and related contents such as nutrient transport, use types, biodiversity and interactions with plants from molecular biology to ecology will be covered, in which the interactions among biosphere, lithosphere, atmosphere and anthroposphere will be focused on.

Jedes Jahr werden über 300 Mio t Plastik produziert. Es wird angenommen, dass hiervon bis zu 10 % in die Umwelt eingetragen werden wo Plastik aufgrund der hohen Persistenz akkumuliert. Hier fassen wir für Böden die wichtigsten Eintragspfade, Nachweismethoden, Gehalte sowie Reaktionen und Wirkung von Plastik zusammen. Dabei unterscheiden wir zwischen Nano‐ (<100 nm), kolloidalem (<1 µm), Mikro‐ (1 µm ‐5 mm), Meso‐ (5 ‐25 mm) und Makroplastik (>2,5 cm). Nano‐ bis Mikroplastik werden primär z.B. für Hygienemittel produziert oder entstehen sekundär durch Zerkleinerung. Sie reichern sich in der Nahrungskette an, doch ihre Gehalte in Böden sind aufgrund fehlender Analyseverfahren bislang weitgehend unbekannt. Die gefundenen Gehalte an vorwiegend Mikroplastik und größeren Plastikteilen variieren dagegen beträchtlich, von 0–627,000 Teilen m ‐3 im Abwasser, von <3 bis >1200 mg kg ‐1 Kompost oder 1000 bis 24,000 Teilen kg ‐1 Klärschlamm. Risiken bestehen deshalb v.a. für solche Böden, die bevorzugten Eintragspfaden ausgesetzt sind. Für eine Gesamtbewertung jedoch fehlen bislang verlässliche Grenzwerte.
