OG exemplary drawing
 
1. A method of analyzing potassium content in soil, the method comprising:
a) obtaining a soil sample;
b) adding a liquid to the soil sample to form a soil slurry;
c) flowing the soil slurry through a filter to form a filtrate;
d) blending a reagent composition and a surfactant with the filtrate to form a soil mixture; and
e) flowing the soil mixture through an analysis tool along a flow direction whereby a potassium absorbance of the soil mixture is measured; and
wherein the soil mixture comprises a surfactant comprises a surfactant and the flow direction is substantially horizontal and orthogonal to the direction of gravity.
