Thanks to a project funded by Northeast SARE, the University of Vermont Plant and Soil Science Department has just published a guide for farmers and ranchers interested in doing On-Farm Research. Ā The 15 page handout,Ā A Practical Guide to On-Farm Pasture Research,Ā is a good place to start if you’re thinking about trying a new treatment or grazing practice. Ā It will help you think about the question you’d like the answer to, and how to design a trial to make sure you’re taking measurements in a way that will really help you quantify what is or is not happening on the ground.
The part I like best about this booklet is “Step 5: Analyzing Results” where the authors tell us a little about how statistics work and how they can tell us if a treatment really made a difference or not. Ā What we want to know is if any difference we see was caused by chance, or it is actually statistically significant. Ā This section shows us how to use the formula capabilities of Microsoft Excel to run a “T Test” without having to know how to do the math.
If you look at this guide and think “Well, I’d love to know the answer to my question, but I don’t know that I have the time to do all that!” think about coordinating with a local NRCS office or your extension agent. Ā Regional SARE offices offer grants to cover the costs of On-Farm research that can cover the costs. Ā If that sounds interesting,Ā here’s a link to learn more.
