How to analyze fertilizer? All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) – phosphorus(P) – potassium(K)).
How do you measure the effectiveness of fertilizer? The fertilizer solution can be tested using two different methods: sending a sample off to a laboratory or in-house testing with an electrical conductivity (E.C.) meter. Laboratory testing determines the amount of each fertilizer element in the fertilizer solution and the application rate.
Which is the analysis of a complete fertilizer? A complete fertilizer is a fertilizer blend or mix that contains the three main plant nutrients: nitrogen (N), phosphorus (P), and potassium (K), in the forms of potash, phosphoric acid, and nitrogen. On a complete fertilizer label, the ratios of these primary plant nutrients are revealed as the product’s N-P-K ratio.
What is the analysis of grade fertilizer? The fertilizer “grade” or “analysis” is the percent nitrogen, phosphorus and potassium guaranteed by the manufacturer to be in the fertilizer. For historical reasons, nitrogen is expressed as N, available phosphorus as P2O5, and soluble potassium as K2O.

How are epoxies made?
Most common epoxy resins are produced from a reaction between epichlorohydrin (ECH) and bisphenol-A (BPA), though the latter may be replaced by other raw materials (such as aliphatic glycols, phenol and o-cresol novolacs) to produce specialty resins.
