A model for predicting dissolved organic carbon distribution in a reservoir water using fluorescence spectroscopy [PDF]

, 2004
A number of water treatment works (WTW) in the north of England (UK) have experienced problems in reducing the dissolved organic carbon (DOC) present in the water to a sufficiently low level.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, EarlyView.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Possible role of organic matter in radiocaesium adsorption in soils [PDF]

, 2002
The aim of this review is to examine the hypothesis that organic matter decreases the adsorption of radiocaesium on clay minerals. The factors that determine radiocaesium mobility and bioavailability in soil are briefly outlined to show why a ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

PLANTS, PEOPLE, PLANET, EarlyView.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Improving Liquid Fertilizer Urea Efficiency Using Humic Acids Additives Extracted from Tropical Peat [PDF]

, 2009
One of the most important sources of organic matter is peat. Being organic in nature, peat are high in humic and fulvic acids. These substances can be reconstituted with N and K to produce ammonium and potassium-h u mates (organic fertilizer).

Mercury speciation, transformation, and transportation in soils, atmospheric flux, and implications for risk management : a critical review [PDF]

, 2019
Mercury (Hg) is a potentially harmful trace element in the environment and one of the World Health Organization's foremost chemicals of concern. The threat posed by Hg contaminated soils to humans is pervasive, with an estimated 86 Gg of anthropogenic Hg

Plant biostimulants and their potential role in achieving the United Nations sustainable development goals

PLANTS, PEOPLE, PLANET, EarlyView.
Plant biostimulants are substances that are obtained from a variety of sources and are applied in minute quantities to enhance plant growth and vigor. In this review we detail how the use of plant biostimulants may contribute to efforts to achieving a number of the UN Sustainable Development Goals.

Phosphorus adsorption and release dynamics in calcareous soil as affected by humic and fulvic acids

Journal of Degraded and Mining Lands Management
Humic and fulvic acids play a crucial role in enhancing phosphorus retention in calcareous soils. These organic acids increase phosphorus fixation on soil surfaces, thereby strengthening its binding and modifying its availability in the soil solution ...

Humic Substances from sediments of Lobos Pond (Argentina). Isolation, Characterization and Limnological Implications

Eclética Química, 2018
Humic substances (HS) were isolated from the sediments of Lobos Pond (Argentina) using mild conditions to preserve their native structure. The HS (humic and fulvic acids) were characterized by means of elemental analysis and FTIR spectroscopy.
