Yak Trace Elements Controlled Release Supplementation
<
2016/4/26
Two field trials were carried out to evaluate the performance of a soluble glass copper, cobalt and selenium bolus for maintaining adequate levels of the three trace elements in yaks. Forty yaks were ...
Potential role of copper availability in nitrous oxide accumulation in a temperate lake
copper nitrous oxide accumulation temperate lake
<
2014/4/22
Denitrifying bacteria require copper for the synthesis of nitrous oxide reductase. In the absence of sufficient bioavailable Cu, nitrous oxide (N2O) may accumulate in natural waters during denitrifica...
