Using drip irrigation helps minimize fertilizer and nutrient loss that can come with other irrigation systems. Drip irrigation minimizes water run off and soil erosion because the water application is so precise and local.
Some of the advantages of drip irrigation included the ability to irrigate irregular shaped fields or flower beds and allows the safe use of recycled water. Moisture within the root zone can be more regularly maintained, which helps minimized soil erosion.
Irrigation systems are important in general to keep your landscape healthy and beautiful. Drip irrigation systems operate at lower pressures than other types of pressurized irrigation, which reduces energy costs to you.
