<p>A process and apparatus are presented for determining plant-influencing frequencies of sound waves for plant stimulation, disease resistance enhancement, nutrient and water absorption improvement. Additionally, a process and apparatus are presented for generating and applying these plant-influencing frequencies of sound waves. Plant-influencing sound wave frequencies are less than about 4,000 Hz, and preferably between about 40 Hz and 1,800 Hz at a sound pressure level greater than or equal to about 70 dB. The Figure is a block diagram which illustrates the preferred acoustic generating apparatus.</p> |
