mean that there is 5 percent nitrogen available?
It means 5 percent total nitrogen, some of which is soluble and the rest is insoluble. To calculate the pounds of product needed to supply x pounds of nitrogen, divided the pounds of nitrogen needed by the percent. Example: 1 lbs. nitrogen/M ft2 divided by .05 (or 5 percent) = 20 lbs./M ft2 (which, by the way, is our standard recommendation). If the customer is using Pro-Booster 10-0-0, the equation would be 1 lbs./.1(or 10 percent)=10 lbs.
