-
Irrigation Basics for Gardens and Small Farms: Water Needs, Goals, and Constraints
+ Exercise: Why is it recommended to group crops into irrigation zones with similar water needs, irrigation method, and sun/wind exposure?
-
Irrigation Basics: Soil, Infiltration, and Root-Zone Moisture
+ Exercise: A vegetable bed has clay soil and tends to puddle or run off when irrigated. Which irrigation approach best reduces runoff while still wetting the root zone?
-
Irrigation Basics: Water Budgeting and Measuring How Much You Apply
+ Exercise: In water budgeting for irrigation, why is it important to define the wetted area (the strip or bed you actually water) before converting inches of water to gallons and setting runtimes?
-
Drip Irrigation for Gardens and Small Farms: Components and Layout Design
+ Exercise: In a hose-bib drip irrigation setup, which component order best protects potable water and helps prevent clogs and pressure problems?
-
Soaker Hoses: Practical Setup, Limitations, and Best Uses
+ Exercise: You notice the first few feet of a soaker hose leave the soil very wet while the far end barely weeps. Which adjustment best addresses the likely cause?
-
Sprinklers and Overhead Watering: Coverage, Uniformity, and Drift Control
+ Exercise: During a catch-can uniformity test, you notice dry strips between sprinkler heads. Which adjustment is most appropriate to improve uniformity?
-
Simple Gravity-Fed Irrigation Systems: Rain Barrels, Tanks, and Low-Pressure Design
+ Exercise: When designing a gravity-fed irrigation zone, which measurement best determines the usable pressure available at the emitters?
-
Irrigation Scheduling: Timing, Frequency, and Seasonal Adjustments
+ Exercise: A garden zone is already on a baseline weekly irrigation schedule. After a week of unusually hot, windy weather, what is the recommended way to adjust the schedule?
-
Preventing Runoff, Evaporation, and Uneven Watering in Real Sites
+ Exercise: During an irrigation test, runoff begins within minutes at the worst spot, but after shutting off and waiting 30 minutes the water has infiltrated. What is the most appropriate next adjustment?
-
Matching Irrigation Methods to Crop Type, Plant Spacing, and Bed Design
+ Exercise: You are irrigating a densely planted bed of shallow-rooted salad greens and want even moisture across the full bed width without dry gaps. Which setup best matches this goal?
-
Basic Maintenance and Repairs for Irrigation Systems
+ Exercise: During a startup inspection, what is the best first check when an irrigation zone has weak output everywhere?
-
Building a Small-Farm Irrigation Plan: Materials, Costing, and Step-by-Step Implementation
+ Exercise: When building and testing a small-farm irrigation system, which approach best reduces rework and makes troubleshooting easier?
About the free ebook
Irrigation Basics: Watering Systems for Gardens and Small Farms
This free ebook provides practical irrigation knowledge for growers who want to deliver water efficiently, protect soil, and support healthy crops. Learn how plant needs, soil texture, root depth, weather, water supply, and site limitations shape a reliable watering approach.
Plan water use with confidence
Build a clear water budget by estimating crop demand and measuring the amount applied. Understand infiltration, root-zone moisture, and the warning signs of under-watering, over-watering, runoff, and uneven coverage. Use this knowledge to set schedules that change with the season rather than relying on a fixed routine.
Choose a system that fits the site
Compare drip irrigation, soaker hoses, sprinklers, and simple gravity-fed systems using rain barrels or tanks. The ebook explains key components, layout considerations, pressure limitations, coverage patterns, drift control, and the practical trade-offs of each method.
Apply water where crops can use it
- Match irrigation methods to crop type, spacing, and bed design.
- Reduce evaporation and runoff through better timing and application rates.
- Improve uniformity by checking pressure, flow, placement, and clogged emitters.
- Adapt watering frequency for rainfall, heat, soil conditions, and crop growth stages.
Create a workable irrigation plan
Turn basic site observations into a small-farm or garden irrigation plan. Explore material selection, simple costing, system setup, routine maintenance, and common repairs. Whether watering raised beds, row crops, or mixed plantings, this ebook helps you make informed, resource-conscious irrigation decisions.
Designed for practical use: apply the principles to create a watering system that is manageable, efficient, and suited to your growing space.
How do I calculate how much irrigation water my garden needs?
Estimate crop water demand, measure the area irrigated, and verify application depth with catch containers or soil-moisture checks.
When is drip irrigation better than sprinklers for vegetable beds?
Drip is often better for closely managed beds because it targets root zones, limits leaf wetness, and reduces evaporation and drift.
Can a rain barrel run a drip irrigation system without a pump?
Yes, for a small low-pressure layout, but flow is limited. Use short lines, suitable emitters, and enough elevation for gravity pressure.
