Stocking rates are expressed as the number of animal unit months (AUM) supplied by one acre of land. The greater the difference between current forage production and the potential forage production of a pasture, the greater the difference will be between carrying capacity and recommended stocking rate.
The fundamental frequency of a wave is the lowest frequency (longest wavelength) that can be used to define its period. The easiest way to understand it is via a musical analogy: The fundamental frequency is the root tone of the overtone or harmonic series.
The Frequency Relationships Between the Modes. If the fundamental frequency for a string is 100 Hz, the first harmonic, or next vibrational mode, would be at 200 Hz. This makes sense as the string is exactly 1/2 the length and therefore would vibrate twice as rapidly. This second vibrational mode of the string is called the second harmonic and is exactly twice the frequency of the fundamental.
