Drip Irrigation on Small Farms

Why do small farms choose drip?

Drip delivers water close to the plant, which leaves leaves dry, reduces evaporation, and uses water more efficiently than overhead systems. It also keeps paths and between-row areas drier, which can mean fewer weeds. For vegetables grown in rows or beds, it is a common choice.

The tradeoffs are upfront labor, cost, and the need to monitor. Tape and tubing can be damaged by animals, tools, and sun, and emitters can clog. A drip system is not a set-and-forget tool.

Think about the scale of your farm too. A small kitchen garden may be fine with a hose, while a market plot of several beds quickly repays the time that drip saves. Walk through a typical week of watering by hand and count the hours before you decide.

• Less water lost to wind and evaporation
• Dry foliage can mean less leaf disease
• Weeds are limited to the wetted zone
• Needs regular checking for leaks and clogs

What are the main parts of a system?

A typical setup includes a water source, a backflow preventer where required, a filter, a pressure regulator, a mainline, submains or headers, and the drip tape or tubing in the beds. Valves allow you to water different zones separately, and timers can automate the schedule.

Filters and pressure regulators protect the system. Pond or stream water carries more debris than well water and often needs more filtration. Your supplier or extension office can help match parts to your water.

Buy parts that fit together and are sold with clear specifications. Mixing fittings from different makers is a common source of leaks, and a local supplier who knows your water can save you from costly trial and error.

How do I lay it out?

Start with a map of your beds, the water source, and elevation changes. Group beds with similar crops and spacing into zones. Keep runs within the lengths recommended for the product you choose, since flow drops off on long runs and the far end of the row can go thirsty.

Choose tape or tubing with emitter spacing that matches your crop spacing. Closely spaced crops like carrots suit different layouts than widely spaced crops like tomatoes. One or two lines per bed is common, depending on crop and soil.

Lay the mainline along the high side of the field when you can, so that water flows with gravity rather than against it. Leave a little slack in the tubing to allow for temperature changes, and anchor lines so wind does not move them.

How long and how often should I run it?

Run times depend on soil type, crop, weather, and how much water the system delivers. Sandy soils need shorter, more frequent runs, while heavier soils can run longer between watering. Check how far the water has moved by digging next to an emitter an hour after watering.

Start with guidance from your extension office and adjust based on what you see. Overwatering wastes water and can drown roots, and underwatering stunts growth.

Write down your run times and what the soil looked like afterward. A season of notes lets you fine tune the schedule so each crop gets what it needs and nothing more, which saves water and pump time.

What maintenance does it need?

Walk the lines regularly looking for leaks, pinches, and wet spots. Flush lines and clean filters on a schedule, because dirt and algae can clog emitters. Rodents sometimes chew tubing, so check after they become active in your area.

Before winter, drain the system and store parts as directed by the manufacturer to prevent freeze damage. Tape is often replaced each season, while tubing may last longer if cared for.

Keep a small repair kit of fittings, punches, and spare tape in a labeled bucket so a leak is a ten minute fix rather than a lost afternoon during a hot spell.

• Check for leaks every week during the season
• Clean filters on a regular schedule
• Flush the lines at the end of the season
• Drain and store parts before freezing weather

Can I use fertilizer through the system?

Some growers inject soluble fertilizer through drip lines, which is called fertigation. It needs proper equipment, such as injectors and backflow protection, and it can clog emitters if done wrong. Ask your extension office or a qualified irrigation professional before trying it.

Also be careful about water safety. If you sell fresh produce, ask your state agriculture department what water testing or food safety rules apply to your irrigation water.

What does it cost, and is help available?

Costs vary by region, supplier, and size, so get several quotes and count labor and replacement parts. Compare cost per bed rather than headline prices.

Some programs offer cost sharing for efficient irrigation. Contact your local NRCS office or Farm Service Agency to ask what is available and how to apply. Rules and funding change, so do not rely on old information.

Ask neighbors who run drip systems what they would do differently. Their experience with local water, pests, and suppliers is worth more than any brochure.
