* NOTE: thinkSOIL™ does not test for Nitrogen and it is not reported in our results due to its volatility. In other words, the amount of nitrogen today may very well be different tomorrow. Any lab that makes recommendations on nitrogen based on the result from their test does a disservice to you and the environment. Instead, nitrogen needs are expressed in allowed pounds per 1,000 square feet with season-by-season application rates. We’ll bore you below with the details, but know that we making recommendations for nitrogen that will be good for your lawn and the environment.
The stated amount of 3.6 pounds/1,000 sq. ft. must be applied throughout the year with approximately .9 pounds/1,000 sq. ft. applied in the spring, in early fall, again in late fall with a final application of .9 pounds/1,000 sq. ft. in early winter (prior to the ground being frozen).
