primer on urea use?
I have been given a 50lbs bag of granular urea.
It's not something I have used in the past and I understand that it has some idiosyncrasies in it's use....vaporization when not incorporated to soil, high burn potential,etc...
I also understand that it can be applied in a number of fashions: solution to the soil or as foliar spray, broadcast, etc.
So what are the techniques that folks use with the product? What kind of application rates and cautions when using?
