    That much carrier breaks surface tension( you should know this). With the products Ric and myself use, I run as high as 4 gpm. I also run a few ride ons and they are 1/4 gal p/1000. Straight weed killer does not require a lot of carrier.

    Btw, wheres the info on this so called study...

    I have shoehorned 2.5 lb ammonium sulfate, 1 lb potassium nitrate, and micronutrients into 2 gallons for application to 1000 sq ft. This mix instantly browns out a lawn unless I am applying immediately before each irrigation zone goes on for 1/4 of its usual time. Applying this same rate of fertilizer in 5-10 gallons makes watering in unnecessary. If I cannot water in, more water is a good idea.

    What studies are those, if I may ask?

    Are you saying you put out 3lbs of N per thousand?

    Carrier rate also depends on what kind of feed your trying to do. Foliar feeding you want low carrier rates if you want the roots to uptake the feed then yes higher carrier rates would be better

    Turf can only Foliar up take about a 1/10 of pound of N per 24 hour period. So enough carrier to reach the root is necessary if you are applying more than a small amount of N.

    Therefore there should be a healthy balance between Carrier and the quantity of Fertilizer being applied. To strong of a salt solution (fertilizer) will burn turf.

    What setup are you using to make your rounds? Pulling a hose or some type of ride-on with a nursery tank? Not too long ago you were rebuilding a golf course spraying rig? What size tanks on whatever you are using?

    I am pulling hose off my 20 yr old TG/CL Isuzu cab over truck with a PTO powered H 25 Hydra cel pump. I actually have Lawnsite to thank for being able to find a working TG/CL truck that wasn't stripped. I bought it over 10 years ago for $ 4250 in Perfect running condition. Of course I made several modification to fit my needs including Paint jobs and new seats Etc.

    Here is a Picture of Ric's Mobile corporate office.

    Here is the 150 gallon toro ride on, FORMER Golf Course sprayer I call Ric's Ride. It is a work in progress and I use it only for insecticides mainly Fire Ant control. It is calibrated at 3 gallon per thousand and I wish I could get more volume. Not shown is the Herd Bait Spread that attaches to the front and a 100 ft hose reel which I have to reinstall by welding a frame for it.

    Here it is on the Job

    Goodness no. That translates to a little over 1/2 lb of N per 1000. To put down 3 lb of N per 1000, that would be around 10 lb of ammonium sulfate and 5 lb of potassium nitrate. That rate probably will kill the grass, no matter how much water is used to apply it. I am doing low rate feedings every 30 to 45 days. I am not trying to apply the entire yearly requirement in one application.

    Golf Greens might have the very same type treatment every 7 to 14 days. The type soil plays a big part of how successful a liquid program is. I should say that the other way. A successful liquid program is designed to the type of soil and climate. What works for you might not work for me etc.

    But the bottom line is the Bottom line. I mean Profit drives the market and every market is different. So is Liquid Fert right for you?????
