Organic Amendments for Landscape Soils [PDF]
, 2021 Author(s): Downer, Jim; Farber, Ben | Abstract: Organic amendments are added to modify a soil in the zone where roots will grow— unlike mulches, which are applied to the undisturbed soil surface. These materials may be incorporated into landscape soils to improve plant growth. However, research has not shown that adding amendments to planting holes for

Alternate Nitrogen Amendments for Organic Fertilizers [PDF]
The Scientific World JOURNAL, 2001 The use of compost or manure in agriculture as an organic source of nutrients is common in many tropical, developing countries like Nigeria. One of the drawbacks of such materials is their low nitrogen (N) content (=1% N). Farmers commonly use chemical N fertilizers such as urea, calcium ammonium nitrate (CAN), and NPK formulations to obtain better ...

Consistent inter-annual reduction of rice cadmium in 5-year biannual organic amendment.
Science of the Total Environment, 2021 Organic fertilizers may contain cadmium (Cd) and the transformation of organic materials in soil also has a role in soil-plant Cd distribution, both of which lead to Cd accumulation in plant edible parts.

Organic Carbon Amendments for Enhanced Biological Attenuation of Trace Organic Contaminants in Biochar-Amended Stormwater Biofilters [PDF]
Environmental Science & Technology, 2017 This study sought to evaluate how dissolved organic carbon (DOC) affects attenuation of trace organic contaminants (TOrCs) in biochar-amended stormwater biofilters. It was hypothesized that (1) DOC-augmented runoff would demonstrate enhanced TOrC biodegradation and (2) biochar-amended sand bearing DOC-cultivated biofilms would achieve enhanced TOrC ...

Influence of organic amendments on the sorption of pentachlorophenol on soils [PDF]
Journal of Environmental Sciences, 2009 The influence of pH on the sorption of pentachlorophenol (PCP) onto three organic amendments, char, humic acid (HA) and peat, and the effect of organic amendments on PCP sorption to three kinds of soils were evaluated. The sorption of PCP on these sorbents fitted the Freundlich model well, suggesting that PCP sorption isotherms were nonlinear with ...
