Soil analysis is a way to record the characteristics of a plot before starting a fertilization plan. Read the report in conjunction with the crop target, previous applications, and irrigation conditions. ## Take a representative sample Evaluate areas with different soil structures, slopes, or management histories separately. Follow the laboratory's instructions tailored to the crop and plot conditions regarding sampling depth, timing, and the number of subsamples to collect. ## Check the units of measurement Note the analysis method and units used alongside the pH, organic matter, and nutrient element results in the report. When evaluating a result, use interpretation ranges appropriate to the laboratory's method. ## Combine results with plot records Add previous fertilization, irrigation water, and production goals to the analysis. Recording the date, crop, method, and quantity after application makes it possible to compare the plan for the next season.
