Poly Tank Q & A

Posted by Sprayer Depot on Fri, Sep 23, 2016

Poly and PCO tanks are used for a wide variety of applications, from spraying to long-term storage. If you’ve ever wanted to know more about them, though, you’re not the only one. Here are a few of the most commonly asked questions about poly tanks.PCOSprayerTank.jpg

What Is a Poly Tank?

“Poly” is short for polyethylene, a type of durable, nonreactive plastic used to make liquid storage tanks. Poly tanks come in all shapes and sizes.

What Is a PCO Tank?

PCO stands for “pest control operator”. PCO tanks are simply poly tanks that are specially designed for pesticide dispersal.

What Kinds of Liquids Can Be Stored?

Because poly tanks are so strong and resistant to chemical reactions, a variety of different chemicals can be stored within them. Unlike some metal tanks, they won’t corrode or react with the contents. It is important to remember, however, that tanks have a limit when it comes to the weight of the liquid they can carry. It’s generally recommended that liquids with a specific gravity of over 1.7 should not be stored in a poly tank.

A few liquids that can be kept in poly tanks include:

  • Water
  • Herbicides
  • Insecticides
  • Cleaning solutions

What Are Some Potential Applications?

Poly tanks can be used for many different purposes; a common one is storage of industrial chemicals. They can also be used as sprayer tanks, working as part of an spray rig designed to disperse pesticides or other liquids.

Are Fittings Included?

Some poly tanks do not have fittings installed. However, they are relatively easy to add and can be found on our website by clicking here.

Where Can I Find Poly Tanks?

Tips to Calibrate Boom Sprayers

Posted by Sprayer Depot on Mon, Sep 12, 2016

ReCalibrating Your Sprayer Throughout the Growing Season 

Farmers should calibrate sprayers once before the spraying season starts and recalibrate them frequently throughout the spraying season to ensure their accuracy, according to Erdal Ozkan, PhD, an agricultural engineering professor who also has appointments with Ohio State University Extension and the Ohio Agricultural Research and Development Center (OARDC).

As he writes in this post, the primary goal with calibration is to Calibrating_a_Sprayer.jpegdetermine the actual rate of application in gallons per acre, then to make adjustments if the difference between the actual rate and the intended rate is greater or less than 5% of the intended rate. This guideline is recommended by USEPA and USDA. Read the full post below to learn more.

Calibrate Your Sprayer Now - Here Is an Easy Way to Do It

Check all the components of the sprayer to make sure they are in working order...the only way you can achieve maximum accuracy from a sprayer is by calibrating it once before the spraying season starts, and recalibrating it frequently throughout the spraying season. While applying too little pesticide may result in ineffective pest control, too much pesticide wastes money, may damage the crop and increases the potential risk of contaminating ground water and environment. The primary goal with calibration is to determine the actual rate of application in gallons per acre, then to make adjustments if the difference between the actual rate and the intended rate is greater or less than 5% of the intended rate. This is a recommended guideline by USEPA and USDA.

Before starting calibration, make sure you have a good set of nozzles on the sprayer. Nozzles wear out through extended use causing over application, or some nozzles may be plugged. Clean all the plugged nozzles. Check the output of all the nozzles for a given length of time at a given spray pressure. Compare output from each nozzle’s output with the expected output shown in the nozzle catalog for that nozzle at the same pressure. Replace the nozzles showing an output error of more than 10% of the output of the new nozzle. Once you do this, now you are ready to calibrate your sprayer. 

Calibrating a boom sprayer is not as difficult as it sounds. There are several ways to calibrate a sprayer. Regardless of which method you choose, it usually doesn’t take more than 30 minutes, and only three things are needed: a timer (or watch or smart phones) showing seconds, a measuring tape, and a jar graduated in ounces. Here, I will describe perhaps the easiest of all the methods to calibrate a sprayer.

To calibrate a boom sprayer for broadcast applications using this method, follow these steps:

  1. Fill the sprayer tank (at least half full) with water.
  2. Run the sprayer, inspect it for leaks, and make sure all vital parts function properly. 
  3. Measure the distance in inches between the nozzles.
  4. Measure an appropriate travel distance in the field based on this nozzle spacing. The appropriate distances for different nozzle spacing is as follows: 408 ft for a 10-inch spacing, 272 ft for a 15-inch spacing, 204 ft for 20-inch spacing, 136 feet for a 30-inch spacing, and 102 feet for a 40-inch spacing.
  5. Drive through the measured distance in the field at your normal spraying speed, and record the travel time in seconds. Repeat this procedure and average the two measurements.
  6. With the sprayer parked, run the sprayer at the same pressure level and catch the output from each nozzle in a measuring jar for the travel time required in step 5 above.
  7. Calculate the average nozzle output by adding the individual outputs and then dividing by the number of nozzles tested. The final average nozzle output in ounces you get is equal to the application rate in gallons per acre. For example, if you catch 15 ounces from a set of nozzles, the actual application rate of the sprayer is equal to 15 gallons per acre.
  8. Compare the actual application rate with the recommended or intended rate. If the actual rate is more than 5 percent higher or lower than the recommended or intended rate, you must make adjustments in either the spray pressure or the travel speed or in both. For example, to increase the flow rate you will need to either slow down, or increase the spray pressure. The opposite is true when you need to reduce application rate. As you make these changes stay within proper and safe operating condition of the sprayer. Remember increased pressure will result in increasing the number of small, drift-prone droplets.
  9. Repeat steps 5-8 above until the recommended application error of +5%  or less is achieved.

Polyethylene tanks are a popular choice in commercial applications. They are reliable, cost-effective and available in many sizes. Most commonly known as poly tanks, these tanks offer many advantages that make them the go-to type of tank for your sprayer. Poly tanks are relatively easy to handle, won’t corrode and are compatible with many liquid chemicals.
