Why Use Subsurface Drip Irrigation?

 

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 drier soil surface and reduces weed germination

 

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

system type

 

Short Term SDI

 

System life expectancy of 3 to 10 years.

Typically utilized for mid-valued crops

Drip tubing typically installed between 3" and 10" of surface

Designed to deliver peak ET demands of crop

 

Long Term SDI

 

System life expectancy 20+ years.

Typically utilized for commodity crops

Drip tubing typically installed between 12" and 18" of surface

Designed to utilize soil holding capacity and irrigation timing to deliver peak crop demand

 

maintenance

 

Pressure & Flow Rate

 

Make sure the system operates according to the required pressures. System pressures and flows need to be monitored to ensure peak performance and maximum system life.

 

Filtration

 

Monitoring filtration performance is necessary.

Filtration requirements vary with water quality, dripper specifications, and other factors. Maintenance requirements for filters vary with type of filter (screen, disk, media, etc.) and water quality.

 

Chemical Treatment

 

Acid injection can reduce the precipitation caused by chemical contaminants. Acid wash (shock treatment) can reduce the build up of contaminants in the drip lines.

Chlorine injection restricts the growth of biological / organic contaminants like algae, bacteria & slime.

Chlorine oxidizes iron & manganese, into insoluble salts which can be separated from water, and reduces sulfur bacteria.

 

Pest Management

 

Pest Management is an essential maintenance function throughout the season.

 

 consideration

 

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, requirements, and rotation

Cultural practices - Seed germination, tillage practices, and harvesting

Drip line 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 drip lines

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
