CA Lessons: Landscaping To Reduce Wildfire Risk
While there are no ways to fireproof a property, there are strategies to design and maintain landscapes for reduced vulnerability. Click here to learn more.
Lesco 32-5-7 has N breakdown of 30.1% urea, 1.1% Ammoniacal = 32% total. The scu is their trade mark poly coated scu (sulfur coated urea. Basically, this means an extended release of N to the lawn, ie a more steady & longer growth response.
Poly coated SCU isn't SCU. It is called POLYMER COATED SULFER COATED UREA, sulfer coated urea and polymer coated sulfer coated urea are two entirely different things. Poly coated SCU is SCU with a Polymer sprayed over Sulfer coated urea, hence two different release vehicles.
regardless of the vehicle (pscu, scu, mbdu, ibdu) the label always says how much of the N is slowly available, then states the #'s of N slowly available too.
the analysis works like this:
35-5-7 (25% scu)
lets say you have 100#s of product.
35#'s is nitrogen
5#'s is phosphorus
7#'s is potassium
of the 35#'s of nitrogen 25% of the 35#'s is scu meaning that
7.20#'s is scu. when you do the math it comes out to 8.75#s but with the percentage of N from the scu is also a variable. It is a little deceiveing for the companies to do this but they all do it this way.
