The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%

The left cerebellum shows decreased activity, and the right cerebellum shows increased activity when an individual is learning a mirror-reading task.
Body parts are moved by several regions of the cerebrum. While the right side of the brain directs movement on the left side of the body, the left side of the body is directed by the right side of the brain. The right hemisphere manages the left side of the body, while the left hemisphere manages the right.
The left hemisphere, for instance, has been found to be better at creating associations in memory, selective attention, and positive emotions. Contrarily, research has found that the right hemisphere performs better in terms of pitch perception, arousal, and negative emotions.
