</font><font color="blue" class="small">( newtothis, sorry that it has been so long, I haven't made it to TBN for a couple of weeks. I have to admit that your question is probably over my head. The only experience I can share is that when spraying 3 acres of lawn I go through 125 to 175 gallons of spray. I haven't made it up to spray the food plots yet. )</font>
Wholey molley! You are putting on 50 gallons of spray per acre?????? Don't know what you are spraying tho, so might be right.
Roundup likes a very low volume of spray. You should be at 8-10 gallons per acre. One needs to change the spray tips & the pump pressure & the ground spead to come up with that. Also to eliminate drift as much as possible a low pressure, such as 20# is good. With the right tips you might want to be near 50# tho - hard to say.
To answer the fellow's question, he needs to calibrate his sprayer. Fill it, or fill it to 50 gallons with plain water. Spray until the water is used up, and measure how much square feet of ground is covered. Divid by 43,560 to get # of acres covered. Then you can figure out how many gallons you are spraying per acre.
If you are around the 10 gallon mark, good to go. If not, you need to adjust ground speed, pressure, or change sprayer tips.
Let's pretend you are right at 10 gal / acre. So you want to spray 3 acres today. You would put 30 gallons of water in the tank, and add 3 quarts of Roundup (common to use a quart an acre, but different formulations of glysophate require different actual useage). Agitate for a bit, & go spray.
There is _no_ way to say how many acres or gallons to mix for a new sprayer. Depends on the pressure you run - which depends on the type of tips you have. You _must_ do a test run & figure it out. If you don't like measuring out how much ground you covered: If you know you have a 3 acre plot or something, fill the sprayer with water, spray the 3 acres, and see how much you used from the tank. You gotta do something to get calibrated.
