Abstract
A method for supplying fertilizer to a lawn, garden, golf course, farm, field, or other agricultural growing area. The method may include the steps of obtaining a soil sample from the agricultural area, measuring a nutrient content of the soil sample with a soil analyzer device, obtaining data for the size of the agricultural area, and electronically calculating the fertilizer required for the agricultural area based upon the soil nutrient analysis and area size data. In certain embodiments, the measuring step may include the steps of passing water heated to a temperature of at least 90° C. through the sample under pressure of at least 2.0 bar, collecting the water passed through the sample, and analyzing the nutrients transferred from the soil to the water.
