no runoff of water leaves silt deposits behind, which reduce the ability of plants to grow. While extensive use of water from aquifers does create major problems, it is evaporation of water used in irrigation that can leave behind excess salts and minerals, which over time can reduce the fertility of the land. The use of drip irrigation systems, which reduce water usage, and only irrigating at night when less of the water evaporates can over time reduce costs, protect the fertility of the land, and conserve valuable water resources.
