| SDI System Types |
|
Factors determining selection of short term SDI and long term SDI.
Soil Types
Crop Rooting Depth
Seed Vigor
Water Salinity
Crop Rotation and Tillage Practices
Water Efficiencies |
|
| (According to soil type and crop) |
|
| 1 |
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 |
| |
| |
| 2 |
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
