Cadmium binding by fractions of dissolved organic matter and humic substances from municipal solid waste compost.
The agricultural practice of amending soils with composted municipal solid waste (MSW) adds significant amounts of organic matter and trace metals, including Cd. Under these conditions, soluble organic complexes of Cd formed in the compost may be more significant than previously thought, due to Cd bioavailability and mobility in the soil environment. To study the relative importance of differen...
متن کاملEffect of Composted Organic Matter on Boron Uptake by Plants
B is one of the seven essential micronutrients Boron uptake by plants is controlled by the B level in soil solution required for the normal growth of most plants. rather than the total B content in soil. The affinity of organic matter for However, the range of B concentrations in the soil soluB can affect B uptake by plants because of changing B concentration in tion causing neither deficiency ...
متن کاملXiphinema americanum as Affected by Soil Organic Matter and Porosity.
The effects of four soil types, soil porosity, particle size, and organic matter were tested on survival and migration of Xiphinema americanum. Survival and migration were significantly greater in silt loam than in clay loam and silty clay soils. Nematode numbers were significantly greater in softs planted with soybeans than in fallow softs. Nematode survival was greatest at the higher of two p...
متن کاملPyrene fate affected by humic acid amendment in soil slurry systems
BACKGROUND Humic acid (HA) has been found to affect the solubility, mineralization, and bound residue formation of polycyclic aromatic hydrocarbons (PAHs). However, most of the studies on the interaction between HA and PAH concentrated on one or two of the three phases. Few studies have provided a simple protocol to demonstrate the overall effects of HA on PAH distribution in soil systems for a...
