That legumes improve soil fertility is well established, however the extent that N fixed by legumes may increase trace gas emissions is poorly understood. Our aim was to determine if greater soil N in native prairies interseeded with alfalfa would in

A network of eddy covariance (EC) and micrometeorological flux (METFLUX) stations over corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] canopies was established as part of the Soil Moisture–Atmosphere Coupling Experiment (SMACEX) in central

Summary The turnover of residue carbon in soil containing little available N can affect the management of crop residues. The effects of N deficiency on CO2 release from decomposing wheat straw were measured in an incubation experiment and interpreted

Methane (CH 4 ) is an important greenhouse gas, and it has been estimated that 50% of annual CH 4 comes from terrestrial systems. Better and more accurate methods are needed to quantify CH 4 flux from terrestrial environments. Two general methods com

During the summer months a dense population of green sulfur bacteria was observed in meromictic Knaack Lake, Wisconsin, at a depth where oxygen was not present. During the day, H/sub 2/S was also absent at this depth but built up at night. /sup 14/CO
