Application of soil amendments is considered as a potential method for maintaining soil health; however, the underlying soil-health-promoting mechanisms are poorly understood. In the present study, we used lime, organic manure, and straw biochar, or their combinations, to treat severely acidified ...
The main objective of this study was to immobilize heavy metals in contaminated soil collected from the Dabaoshan area of Shaoguan City, Guangdong Province using inorganic-organic mixed amendments. A batch of incubation experiments were firstly conducted to study the efficiency of mixed amendments (lim...
Amendments in the glucose content of soils accelerated the reductive condition of soils, and made it more suitable for Cr(VI) reduction. Addition of phosphate decreased Cr(VI) sorption due to the competition for sorption sites.doi:10.1080/10934529809376807...
Conclusions The biochars produced from legume crop straws were better choices as amendments for acid soils than their feedstock. Organic anions and carbonates were the main forms of alkali in the biochar; both contributed to neutralizing soil acidity and increasing soil pH. The incorporation of ...

The improvement of soil quality for these soils is a key goal for sustainable agriculture. The purpose of this study is to evaluate the beneficial effects of biochar amendments on the soil acidity, plant available nutrient contents, and physical properties of a strongly acidic Ultisol. A Typic ...
Use of different organic and inorganic amendments has been reported in previous studies to enhance soil pH and PUE22,23. In a previous study, we observed that application of wheat straw or pig manure in combination with inorganic fertilizer increased the phosphatase activities and PUE24. Addition ...
Microcosm Experiment for Evaluating Efficiency of Chemical Amendments on Remediation of Heavy Metal Contaminated Soil Heavy metal pollution in agricultural field near the abandoned metal mines is a critical problem in Korea. General remediation technique is to apply chemical amendments and soil covering. ...
amendments efficiently reduced CaCl2- exchangeable Pb, Cu (1.7–two fold), and Zn (33 fold) if compared to the untreated MT. The improvement of physicochemical properties of MT resulted in an increase in soil microbial abundance and in the activity of urease, dehydrogenase, and alkaline ...
The present study shows that the carbonate amendments, especially single SF, can be used to increase the sorption capacity of typically mobile toxic elements (As, Cd, and Tl) in an acidic soil. The effectiveness of the SF application followed the order Cd > As > Tl. The sorption data for...
