Intro

The following are some early assessments on visualizing and summarizing the data for 2024 Soil samples

Below are the initial summary values for each nutrient tested from Ward Laboratories.

In visualizing the data, I used these datasets to perform

Soil Pivot table of average nutrient values compared to fire severity

## `summarise()` has grouped output by 'Fire_Severity'. You can override using the
## `.groups` argument.
