An important part of being a steward of the land is knowing what is in your soil and how to make informed management decisions based on what you are growing and your site specific conditions. Whether you are growing a garden, lawn, pasture, orchard, or row crops, soil testing is an important part of dialing in your nutrient management. It is also a way to conserve resources and save money by only applying what you need.

If you aren’t testing, you’re guessing!

When you get nutrient testing performed through our district, you get more than just numbers.

  • A soil analysis report, which tells you the levels of each nutrient in your soil.
  • A write up interpreting your results which will help you see whether each nutrient is high, low, and what the optimal ranges are for each nutrient.
  • Recommendations for what to apply, how much, and when based on the crop you are growing and general recommendations for our area (organic or conventional, based on preference).

Our recommendations follow land grant university guidelines and research that has been done for specific crop needs.

Our Basic Soil Test costs $25

  • Organic Matter
  • pH (soil and buffered)
