Based Soil Texture Volume

Determination of soil texture by using the volume percent can be simpler than the method hydrometer. The principle of determination based on the percent of this volume is based on the speed of precipitation. Wherein the fraction of the rough or the sand will settle early (1 minutes before turning it) and then followed by the fraction of the dust ...

Determination of Levels Alkalinity

Alkalinity is a total concentration of alkaline elements contained in water and commonly expressed in mg / liter or the equivalent of calcium carbonate (CaCO3). It is said that the alkalinity in freshwater very important role because alkalinity is not only a direct effect on the growth of plankton, but also affects other parameters. Alkalinity is the capacity of water ...
