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 frequencies of the harmonics are whole-number multiples of the fundamental frequency. If the fundamental frequency were 1 Hz the frequency of the second harmonic would be 2 Hz, the third harmonic would be 3 Hz, the fourth 4 Hz, and so on. If a medium is bounded such that its opposite ends can be considered free, antinodes will then be found at the ends.
