I don't think that is water soluable if in solid form. If it is liquid forms
I f in liquid form, I would use like 1/2 table poon per gallon.
READ THELABEL!

The reason I ask is there are no directions on the container.
I asked in the lawn forum & got knowledgeable responses.
Just so you know it is very soluble in water.
Thanks

OK! Nitrogen should be used with caution. Too much of it will do more harm than good.

Lets do a comparative math. 46% of what is in the bag is pure Nitrogen.
Say, you take two ounces and add two ounces of water to it, you will have,
roughllt a 23-0-0 liquid fertilizer. I will then use about two TBLSP of that solution per gallon of water.
This should fairy compare to liquid tertilizers sold in the bottle. Avoid foliar feeding.

I alway use fertilizers diluted to about 1/3 of the recommended and use it more frequently instead.
This way I avoid getting too much foliage, the excess is not leached down and wasted.

What cyrus said. You can always add more later, say in two or three weeks after you see what the first gentler application did. Fertilizer companies are trying to sell you MORE fertilizer for profit. Start slow, be cautious. Start fast, fry your plants. Urea is one of the "hottest" fertilizers.
