Nitric acid digestion in CEM Mars Microwave system. Method 5.3 from “Recommended Methods of Manure Analysis” and TMECC 4.12 (Adapted from EPA 3051) use for determination of P,K,Ca,Mg,Na,B,Co,Cu,Zn,Mo,Mn,Fe,S,Al 

The digested samples are analyzed on Thermal 6500 Dou ICP. Method 6.3 from “Recommended Methods of Manure Analysis” and TMECC 4.14

Liquid samples are done as-is. Solid samples are analyzed one part sample to 2 parts water. Method 7 from “Recommended Methods of Manure Analysis” 

Liquid samples are done as-is. Solid samples are analyzed one part sample to 2 parts water. Method 8 from “Recommended Methods of Manure Analysis” 

100:1 solution:solids ratio, sample is shaken for one hour at 150 rpm. Sample is then filtered and analyzed on ICP (Reference Wolf, Ann, Peter Kleinman, Andrew Sharpley et.al. Soil Sci.Soc.Am.J
