Actual soil fertility is the amount of nutrients and moisture derived from the soil by the plants in a given year.
See Chapter 3, âwater-soil systemâ. For most water harvesting systems soil fertility must be improved, or. at least maintained, in order to be productive and sustainable. The im-. proved water availability and higher yields derived from water har-. vesting lead to a greater exploitation of soil nutrients.
