Explanation: studies hinged on the relationship between practicing self control and blood sugar levels have been undertaken in the past which results indication that there is a direct relationship between the two. In practicing self control, blood sugar (glucose) is vital as an energy source as acts of self-control deplete relatively great amounts of sugar with failures (with self control) attributed to low sugar level and in instances where insulin (hormone involved in blood sugar metabolism) is low or insensitive thereby hindering mobilization of sugars to the brain.
This provides the soil with nutrients. When the remains of the crops decompose they release nutrients into the ground rather than leaving the ground barren
