Lawns - Liquid lawn fertilizer via sprinkler system

I have my lawn irrigation set up so I can pump water out of a small lake to a water container near the house. I then pump the water out of the container through an inground irrigation system to water my yard. My question is: Is there any type of lawn fertilizer that I can add to the water in the container prior to watering the lawn so that I can fertilize while watering? My main concern would be plugging the nozzles of the gear drive sprinklers. Any thoughts and/or suggestions?

Only water soluble fertilizers like Miracle Gro would work but there's really no way to know if you are applying enough or too much and if it's being applied evenly.

Miracle-Gro Water Soluble Lawn Food - Scotts Miracle-Gro (http://www.scotts.com/smg/catalog/productTemplate.jsp?tabs=general&proId=prod70008&itemId=cat50106&id=cat50006)

These products are designed to be applied by a hose end sprayer made by Miracle Gro and specifically designed to apply them.In a holding tank you can't mix them or know how much is being applied at any given time to any area.Because you can't mix them you can't be sure they won't clog your system.

Frankly I'd either buy the sprayer and apply it properly or stick with regular lawn products applied with a spreader which is by far the most accurate way and which has by far the most options for products and application specifics like winter formulas,weed killing formulas and insect/disease control.

The use of a water based product through a sprinkler system might encourage overwatering which can cause a variety of problems including disease.

You might be looking for something like the EZ-Grow or similar siphoning systems. You will not be applying the fertilizer into the holding tank, but rather into the mainline that feeds your system. When the water runs through the pipe it can siphon out the correct amount as the system waters your lawn.

The problem with just dumping it into a repository is that your first 1-2 zones will get all the fertilizer and then it will run out. That, or the way it is spread out will be very unequal.

Make sure you run a couple cycles of the system before changing to another type of fluid--say bug killer, for example. The two will often form clay-like clumps which would clog everything so only run 1 chemical at a time and run a few cycles or a week before trying a different chemical additive so make sure the system is thoroughly flushed.

Try an irrigation supply house near you and let them know what you are looking for. Keywords for internet searches will be "underground sprinkler siphon fertilizer" --things like that.

Thanks, I didn't know that type of product existed. I think that's just what I want.
