Abstract
Described herein is a method of analyzing nutrient 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, whereby the filter is oriented such that the soil slurry flows downward through the filter at least partially under the effects of gravity, d) blending a reagent composition with the soil slurry to form a soil mixture, and e) measuring an absorbance of the soil mixture.
Claims11
A method of analyzing buffer pH 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 an indicator composition with the filtrate to form a soil mixture;
- and
- e) flowing the soil mixture through an analysis tool along a flow direction and performing chemical analysis on the soil mixture flowing through the analysis tool, whereby a buffer pH value of the soil mixture is measured;
- and
- wherein the flow direction is oriented such that the soil mixture flows downward at least partially under the effects of gravity.
