How Much Water Should Irrigation Provide?

 







The 1-Inch Water Rule

Providing the right amount of water can be challenging because irrigation needs vary. Plant type plays a major role, since grass, flowers, vegetables, and trees all need different levels of moisture.

Other important considerations include soil conditions, wind, sun exposure, and evaporation. Water availability and the type of irrigation equipment you use also affect performance.

Smart irrigation tools such as sensors, weather-based controllers, and automated systems can make watering more efficient. These solutions are helpful but may require higher upfront costs.

Goal of Proper Irrigation

Whether for a garden, lawn, or farmland, every irrigation system should distribute water evenly and efficiently.

Recommended Watering Amount

A trusted rule of thumb is to provide 1 inch of water per week. This has long been considered a useful guideline for many growing environments.

Because rainfall cannot be controlled, irrigation becomes essential during dry periods. If drought continues, repeat the same weekly amount.

How Much Is 1 Inch?

  • 1 acre = 27,200 gallons
  • 1,000 sq. ft. = 620 gallons
  • 1 sq. ft. = 0.62 gallons

Final Thoughts

Although every situation is different, 1 inch per week remains a practical standard for irrigation planning.

Prevent Damage to Irrigation Equipment: Proper Spring Preparation

Image
Introduction Winter's harsh conditions can wreak havoc on even the most well-maintained irrigation systems. Frozen pipes, cracked components, and misaligned sprinkler heads are just a few of the issues that can arise. That's why, as temperatures warm and the growing season approaches, it’s essential to perform a thorough spring startup check, and necessary maintenance, on irrigation equipment.    This guide will walk you through the critical steps of preparing your irrigation equipment for spring, ensuring you avoid costly repairs, and that your irrigation equipment performs optimally. As a bonus, save our spring preparation checklist (at the bottom of this article) to refer back to later.    Pre-Start-Up Checks Before starting up your irrigation system for the spring, the weather is the first thing to consider. If the ground is still frozen, turning irrigation equipment on could damage components and lead to expensive repairs. To avoid this damage, wait until after ...

How Much Water Do I Need to Irrigate?

  Calculating 1" of Water Deciding how much water any plant needs can be difficult.  There are so many factors to consider.  The first seems obvious, what type of plant? Grass, a tomato plant, an apple tree?  Within each plant may be several varieties that may need more water than others. You also need to consider factors such as soil type and evaporation due to wind or sun.  Don’t forget about your limitations on how much water you can access and the irrigation infrastructure (pumps, pipe, filters etc.) in place to capitalize on this opportunity of water. In today’s age there are all kinds of “smart tools” that can help like soil moisture sensors, weather stations, and remote irrigation controls.  These types of tools come with a price tag… as you could expect for such powerful tools.  Some of these can also seem daunting in order to use the tools to its full capacity. At the end of the day, the key to designing an irrigation system is ensuring that i...

Updating the Irrigation System for Your Golf Course

Image
  Start with an Inventory of Your Current System   Before you start thinking about what you would like to change, it’s essential, to begin with, an inventory of your existing golf course irrigation system. Auditing your current system will help you understand the scope of required changes before you add any wish list items.  Major systems you should consider in your inventory include: Pump stations:  Introduce pump stations with efficient, intelligent monitoring capabilities. Remote connectivity is another key feature of modern irrigation systems. Hydraulic network:  Consider the condition of the pipe and fittings as well as the age of your current system. Newer materials can remediate issues caused by ageing systems made of galvanized pipes, asbestos cement, and other outmoded materials. Distribution uniformity:  The sprinklers are tremendously important in any irrigation system. Whether your system uses a valve in the head, spray heads or golf rotors, it'...
