This review focuses on the chemical nature of that fraction of already dissolved organic
matter into soil solution, or extracted by mild extractants, which is truly readily available for …

The ability of plants to compete effectively for nitrogen (N) resources is critical to plant
survival. However, controversy surrounds the importance of organic and inorganic sources …

Protein represents a major input of organic matter to soil and is an important source of
carbon (C) and nitrogen (N) for microorganisms. Therefore, determining which soil …

Soil nitrogen (N) mineralization is generally limited by amino acid production by proteases
(depolymerization). Protease activities can be stimulated under N limitation, but it cannot …

Free amino acids (FAAs) in soil solution are increasingly recognized as a potentially
important source of nitrogen (N) for plants, yet we are just beginning to understand the …

Mineralisation rates provide valuable information concerning the overall cycling of soil
organic N; however, detailed information regarding the pathways preceding the …

The high degree to which plant roots compete with soil microbes for organic forms of
nitrogen (N) is becoming increasingly apparent. This has culminated in the finding that …

Soil organic carbon (SOC) loss from intensive agriculture represents a major global concern.
Consequently, strategies to improve soil management to mitigate or abate SOC losses and …

The environmental issues caused by chrome-tanned leather could not be overlooked, and
the high concentration of chromium (Cr) in the waste leather fragments was a major factor in …

Although Tansley originally proposed the ecosystem concept in 1935, ecosystem science
underwent significant development in the last 20 years, as in this period it has been …
