A large number of soils, worldwide, are acid (normally pH< 5.5) and suffering from on-going
soil acidification. Acid soils or soils undergoing acidification generally have low fertility and …

Soil acidification in managed ecosystems such as agricultural lands principally results from
the increased releasing of protons (H+) from the transformation reactions of carbon (C) …

Extensive acidic soils, which suffer from accelerated soil acidification, are found in southern
China. Soil acidity, aluminum toxicity, and nutrient deficiencies severely limited crop …

Soil acidity is a serious problem in agricultural lands as it directly affects the soil, crop
production, and human health. Soil acidification in agricultural lands occurs due to the …

In China, it is critical to develop new soil amendments to decrease soil acidity because of the
severe soil acidification problems that exist. In the present study, the effects of biochars …

Biochar, because of its porous nature, calcium carbonate (CaCO 3) equivalent, surface
functional groups, and other properties, could serve as an acid soil amendment. To …

In arable soils, anthropogenic activities such as fertilizer applications have intensified soil
acidification in recent years. This has resulted in frequent environmental problems such as …

Strongly acidic soil (eg p H< 5.0) is detrimental to tea productivity and quality. Wheat, rice
and peanut biochar produced at low temperature (max 300° C) and differing in alkalinity …

Purpose The amelioration effects of crop straws and their biochars on an acidic ultisol were
compared in incubation experiments to determine suitable organic amendments for acid …

Biochar has positive effects as a soil acidity amendment which is a global concern.
However, few studies have been reported on the effect of aged biochar on soil acidity …
