Drip System Recommendation From Premier Range:
| Crop Spacing (m) |
Soil Type | Product Selection Premier Range | Lateral Spacing (m) |
Emitter Spacing (m) |
Emitter Discharge (1ph) |
|---|---|---|---|---|---|
| [(0.75+1.25) 0.15] | Clay | Drip-InTM/In-Drip | 2.00 | 0.50 | 2lph/4lph |
| [(0.60+1.20) 0.15] | Loam | Drip-InTM/In-Drip | 1.80 | 0.40 | 2lph/4lph |
| [(0.60+1.00) 0.15] | Sandy | Drip-InTM/In-Drip | 1.60 | 0.40 | 2lph/4lph |
Note: Up to 10acres ZLTM sprinkler is a practical solution, above this the larger models R Series large volume sprinklers are useful. The low operating pressure model ZL 22 LOPSTM is economic on power.
