Subsurface Drip Irrigation (SDI)

Why use SDI? More efficient water use - SDI saves water with decreased evaporation and deep percolation.

Decreased groundwater contamination - SDI decreases leaching of nutrients carried by over irrigation and poor uniformity.

SDI provides the most effective management tool - delivering water and nutrients directly to the plant roots at the precise time and in the precise quantity needed.

Maximizes irrigated acres - SDI irrigates fields from corner to corner and easily adapts to small and odd shaped parcels.

Optimizes plant nutrition - The nutrients carried by the irrigation water are applied directly to the plant roots.

Minimizes weed growth - SDI Irrigation produces a drier soil surface and reduces weed germination.

Enables the use of recycled water - In approved applications without adverse environmental impact. Complies with environmental and public health regulations which prohibit overhead irrigation of certain crops with recycled water.

Eliminates water on foliage which reduces disease incidence.

SDI Considerations What you should consider before choosing an SDI System?

Field layout - Field shapes and sizes Field Conditions - Soil type, depth of topsoil, subsoil type, slope, and topography Water - Availability, quantity, and quality (performing a water quality test is essential) Crops – Type, water requirements and other crops to be included in the rotation Cultural practices - Seed germination method, tillage practices, and harvesting Drip Tape products – Diameter, wall thickness, emitter spacing, flow rate, and filtration requirements Location of drip lines - Depth, distance between laterals, and relation to the crop.

System components and location - Pumps, filters, controls, control valves, lines (main lines, sub-main lines, and manifolds), air relief valves, and SDI drip tape Monitoring - System flow rates and pressures should be monitored to ensure peak performance and maximize system life.

Maintenance procedures -Routine maintenance is necessary for system longevity and optimal performance.
