A forest's ability to store carbon depends on the bedrock beneath, according to Penn State researchers who studied forest productivity and composition and the physical characteristics of roc...
Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
