Drip Irrigation & Fertigation for Commercial Sweet Potato
Sweet potato on ridges responds to steady moisture during root bulking. Commercial growers use one drip tape per ridge with fertigation, planned around water supply and pumping power.
When does sweet potato need the most water?
During establishment and root bulking. Your agronomist sets the schedule; the calculator sizes the system for the peak day you enter. No. They are FAO 2024 national and world averages, mostly rain-fed and open field. They show the starting point, not what drip will achieve on your site.

Typical design envelope
Reference parameters used to open the RFQ. Final values are sized by our engineers against source-water, soil and crop stage.
System components
Thin-wall tape on top of each ridge, removed before harvest.
Dosing channels and EC/pH control, matched to the number of irrigation blocks.
Sand media, disc or screen, chosen from the water analysis.
Mainline, submains and pump sized to the largest block flow.
Block scheduling by timer, with flow and pressure monitoring.
Why drip for sweet potato
- Water goes to the root zone, which matters where allocation or borehole yield is the limit.
- Fertigation splits nitrogen through the season instead of large single applications.
- One request can cover tape, filtration, fertigation, pumping and controls; offers are compared on the same scope.
Local water and power issues by market
| Market | Water | Power | FAO national yield, 2024 |
|---|---|---|---|
| Morocco | Groundwater stress and abstraction permits from the river-basin agency | Grid or solar pumping | 22.8 t/ha |
| Brazil | Water-use grant (outorga) for abstraction; dry-season supply in the Cerrado and Northeast | Rural grid reach and tariffs; solar pumping common | 14.9 t/ha |
| Cabo Verde | Desalinated, borehole or recovered water; storage for supply gaps | High grid cost; solar where possible | 14.0 t/ha |
| Zambia | Borehole yield and dry-season (May–Oct) supply; storage for peak demand | ZESCO load shedding — solar or backup for pumps | 2.8 t/ha |
| South Africa | Registered water-use rights and allocation limits | Eskom load shedding risk — solar or backup for pumps | 2.6 t/ha |

Buyer path
From your site to one drip and fertigation request
- 1 · Define
Crop and site details
State the region and site, crop and growing system (soil or substrate), water source with a recent analysis, storage, power supply and the area to be irrigated.
- 2 · Calculate
Size the critical systems
Use the focused tools below. Results are planning estimates, not engineering designs or supplier quotations.
- 3 · Request
Create one reviewed brief
Add the figures to a private project request. A sourcing specialist reviews it before any relevant supplier is approached.
