Historical increases in emissions and atmospheric deposition of oxidized and reduced
nitrogen (N) provided the impetus for extensive, global-scale research investigating the …

Globally, sulfur (S) applications to croplands result in S inputs that often exceed historical
atmospheric deposition. Sulfur is applied to crops as a fertilizer, fungicide, soil conditioner …

Contemporary soil science and conservation methods of effective forestry Forests and the
soils that serve as their foundation cover almost a third of the world's land area. Soils …

Soil pH buffering capacity (pHBC) plays a crucial role in determining soil acidification rates
and the amount of lime required to ameliorate soil acidity. However, it remains poorly …

Insect abundances are declining in many areas around the world, but the causes of those
declines are seldom clear. Here we report a dramatic decline in the abundance and diversity …

Acid deposition arising from sulphur (S) and nitrogen (N) emissions from fossil fuel
combustion and agriculture has contributed to the acidification of terrestrial ecosystems in …

Soil acidification along with base cations loss degrades soil quality and is a major
environmental problem, especially in agroecosystems with extensive nitrogen (N) …

We summarize past examples of the use of science to document the effectiveness of policy
in air quality management. Our goal is to inform public discourse amidst attempts to negate …

Soil acidity plays a central role in the diversity and function of terrestrial ecosystems. Recent
studies have revealed that acid deposition has acidified topsoil over time. However …

Climate change and atmospheric deposition of nitrogen (N) and sulfur (S) are important
drivers of forest demography. Here we apply previously derived growth and survival …
