We’ve had two days of rain and Wai‘a‘ama Stream is a raging torrent. Incredible amounts of water running down the flume!
In addition to using the water that’s all around us, we utilize the energy of the sun. Because what drives plant growth? Sun energy in a certain range.
Photosynthetically active radiation
From Wikipedia, the free
encyclopedia
Photosynthetically active radiation, often abbreviated PAR, designates the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis….
We use a sensor that measures the sun energy per meter squared and gives a number for the total accumulated in a day. We keep track of the total.
The sun energy total was low these last two days. This is something we expected, because the river has been raging.
Farmers routinely use scientific information. This is why I say farmers have common sense.
