Soil Technician Job Descriptions, Average Salary, Interview Questions

What Does a Soil Technician Do?

Soil technicians are professionals who test and study land to assess viability for specific usage. They analyze soil composition, fertility, and structure and recommend optimal use and sustainability. Additionally, they assess potential risks, such as contamination and erosion, and recommend mitigation measures.

Soil technicians ensure that before a company spends a significant investment in a piece of property, it can be used for its intended purpose. In collaboration with lab technicians and other field technicians, these experts test soil types and compositions to reveal vital information.

These technicians should have a broad knowledge of federal, state, and local environmental regulations, along with ecological reporting and surveying. They should effectively be able to communicate their findings, be it written or verbal, and be comfortable doing significant amounts of fieldwork gathering samples.

  • Management: Do you have the time and expertise to direct the work effectively?
  • Urgency: How soon does the work need to be completed?
  • Headcount: Do you have the budget and approval for an internal employee, or should you consider alternate options?
