The effects of pH and time on the formation of hydroxy-Al, Fe,
and Mg interlayer were compared for montmorillonite and vermiculite.
The stability of interlayers was evaluated by sequentially increasing
the severity of dissolution treatments and by subjecting the inter-layers to an HC1 treatment. The interlayer formation and stability
were...
The study was conducted in order to obtain some understanding of the hydrologic characteristics of streamflow under dry weather conditions, and from this knowledge develop some means for prediction of seasonal-low streamflow quantities.
It was considered desirable to prepare "drought frequency plots" for a number of watersheds of varying sizes...
High protein wheat seeds frequently perform better than low
protein seeds of the same variety. Protein content of seeds can be
increased by management practices, the most important of which is
rate and timing of N applications. The purpose of this study was to
determine the chemical, biochemical and physiological...
