متن کاملThe effect of potassium and magnesium infusion on plasma Mg concentration and Mg balance in ewes.
1. Concentrations of magnesium in plasma, the ionic concentration in rumen digesta supernatant fractions, Mg balance and electropotential differences were measured in three ewes which were fed on grass and supplemented with potassium and Mg by intraruminal infusion. 2. Mean plasma Mg concentrations were unaltered by combined K and Mg treatments, but fell (P less than 0.001) when K alone was inf...

Short communication Soil response to long-term grazing in the northern Great Plains of North America
Grazing management affects ecosystem function through impacts on soil condition. We investigated the effects of long-term (over 70 years) grazing on soil properties and nitrous oxide (N2O) emission within a moderately grazed native vegetation pasture (MGP), heavily grazed native vegetation pasture (HGP), and a fertilized crested wheatgrass (Agropyron desertorum (Fisch. ex. Link) Schult.) pastur...
