Selection of Plant Species–Organic Amendment Combinations to Assure Plant Establishment and Soil Microbial Function Recovery in the Phytostabilization of a Metal-Contaminated Soil

Organic and inorganic amendment application on mercury-polluted soils: effects on soil chemical and biochemical properties

“…The fraction of organic substances contained in digestate may be the main factor responsible since it provides the soil with easily available organic C compounds for microorganisms. Similar findings have been previously described by Alvarenga et al (2008) and Kohler et al (2014). Arylsulfatase is responsible for the mineralization of organic S in soil and represents an important indirect indicator of microbial biomass contained in organic ester sulfate compounds (Bandick and Dick 1999).…”

The potential use of Piptatherum miliaceum for the phytomanagement of mine tailings in semiarid areas: Role of soil fertility and plant competition

“…Due to their heterogeneous nature, municipal solid wastes may show high variability in composition and properties. Thus, prior to field-scale applications, specific assessment tests in controlled conditions must be carried out (Kohler et al, 2014). In our study, the addition of a municipal solid waste to a mine soil caused an increase in salinity and some of the metal(loid)s concentrations.…”

“…to alleviate the deficient fertility conditions for plant growth in mine tailings (e.g. Farrell et al, 2010;Soler-Rovira et al, 2010;Clemente et al, 2012;Kohler et al, 2014). Due to their heterogeneous nature, municipal solid wastes may show high variability in composition and properties.…”

“…Then, it is critical to accelerate these processes by favouring plant growth. Among the different alternatives, the use of organic amendments has been widely employed because of stimulating soil fertility and decreasing metal(loid) mobility (Norland and Veith, 1995;Clemente et al, 2010;Kohler et al, 2014). The performance of organic amendments depends on their nature, the dose and the properties of the polluted soil.…”

Low levels organic amendments improve fertility and plant cover on non-acid generating gold mine tailings

“…Often this involves the addition of organic material and inorganic fertilizer. The addition of organic matter provides nutrients and a source of soil biota including bacteria, fungi as well as invertebrates capable of mineralizing the organic matter into plant available nutrients (Kohler et al, 2014). The need of additional inorganic fertilizer will depend on the C:N ratio of the organic material (Vagstad et al, 2001).…”
