Liberation of low molecular weight organic acids from sedimentary organic matter and their role on microbial activity
Low molecular weight organic acids (LMWOAs) are important nutrients for microbes. However, most LMWOAs do not exist freely in the environment but are bound to macromolecular organic matter, e.g. kerogen, lignite and coal. During burial and geological maturation of sedimentary macromolecular organic …

The effects of biochar on trace element and nutrient solubility in the presence of low-molecular-weight organic acids
Low-molecular-weight organic acids (LMWOAs) secreted by plant roots play an essential role in regulating the phytoavailability of soil-borne trace elements and nutrients. Biochar is widely considered as a suitable soil remediation option, having shown an efficacy to retain both anions and cations. …

Relationships Among Soil Properties and Soil CO2 Efflux in a Loblolly Pine-Switchgrass Intercropped System
… temporal variability of total soil CO2 efflux. Low molecular weight organic acids (LMWOAs), dissolved organic carbon (DOC) and dissolved organic nitrogen (DON), microbial biomass and activity were measured to evaluate the impact of intercropping switchgrass (Panicum virgatum L.) in a loblolly …

Biochelators as an alternative to EDTA and other synthetic chelators for the phytoextraction of heavy metals (Cu, Cd, Pb) from soil
… and is usually costly. For arable land, in which low to medium level contamination threatens soil fertility and human health in the long term, gentle remediation techniques are required which not only reduce toxicological risks, but also restore soil fertility. In order to overcome these problems, …
