Utilization of ammonium as a nitrogen source: effects of ambient acidity on growth and nitrogen accumulation by soybean.
Dry matter accumulation of plants utilizing NH4+ as the sole nitrogen source generally is less than that of plants receiving NO3- unless acidity of the root-zone is controlled at a pH of about 6.0. To test the hypothesis that the reduction in growth is a consequence of nitrogen stress within the plant in response to effects of increased acidity during uptake of NH4+ by roots, nonnodulated soyb...

متن کاملCyclic variations in nitrogen uptake rate of soybean plants: ammonium as a nitrogen source.
When NO3- is the sole nitrogen source in flowing solution culture, the net rate of nitrogen uptake by nonnodulated soybean (Glycine max L. Merr. cv Ransom) plants cycles between maxima and minima with a periodicity of oscillation that corresponds with the interval of leaf emergence. Since soybean plants accumulate similar quantities of nitrogen when either NH4+ or NO3- is the sole source in so...

متن کاملThe net utilization of ammonium nitrogen by the growing rat.
While it is well known that ruminants (with the aid of rumen microorganisms) can utilize ammonium salts and urea in lieu of dietary protein,” 2 it has long been held that monogastric animals cannot.’ In view of the findings of Foster, Schoenheimer, and Rittenberg3 that dietary ammonium N15 is rapidly incorporated into rat tissue proteins, it seemed possible that the nitrogen of ammonium salts m...
